A water pump performs one extremely vital function that ensures your car’s engine works as smooth as possible. The water pump is a vital part of a vehicle’s cooling system, providing a constant stream of coolant to the powertrain. The continuous flow of liquid does not allow the engine to overheat. In other words, if the water pump fails, so does the engine, and that’s what you don’t want.

It helps to learn more about the water pump as a part of the car’s cooling system. If it fails or if there is an issue, you should have a basic idea about all its components and which one to replace.

 

Main water pump components

 

A water pump has several small parts that join together to make one working machine. Its most basic components include the hub/pulley, bearing, body/house, seal, and impeller.

 

1. The Hub or Pulley

 

A water pump’s pulley is designed to transfer the drive belt’s movement into the bearing spindle. The pulley receives the engine traction and acts as a medium between the two, mediating the amount of torque that goes through.

Since the pulley experiences a lot of pressure and force from the drive belt, it has to be made of strong materials. The pulley is usually made of steel, cast iron, or sheet metal. The idea is to produce a strong pulley that is lightweight and durable.

 

2. Spindle bearing

 

This is one of the most important water pump components and comes next in line after the pulley. It receives the turning force from the pulley and transfers it to the next component in line, which is the impeller. The bearing’s design and build quality is the sole factor behind the water pump’s lifespan. The bearing is a set of metal balls that turn and twist to do their job.

There are two types of bearings: roller-ball and ball-ball. The roller ball design allows for more durability and smoother function compared with the other. Therefore, most water pumps have a roller-ball design.

3. Body

 

The body is the basic structure of the water pump that holds the liquid and where all the transferring takes place. The other components stick to the body to create the water pump that you see with your eyes. Hence, the water pump’s body has to be made of immensely strong materials that can withstand the water pressure produced inside. 

Water pump bodies are mostly made of lightweight aluminum, but some are built using cast iron. On one end, the body is connected to the pulley, and on the other, it is joined with the car’s cooling system.

 

4. Seal

 

Since the bearing is made of metal balls, the risk of corrosion is high. As such, the component needs to be protected from any exposure to liquid. The seal is put in place to protect the bearing from any contamination and to shut the pump tight. If there is any leak, the water pump will not produce sufficient pressure, resulting in failure. Hence, the seal plays an important role in keeping the water pump intact.

Dolz uses the most modern dynamic seals in the market, which ensures long water pump life when it is used with appropriate quality liquid.

 

5. Impeller 

 

The impeller is a rotor that is used to increase the pressure and flow of liquid inside a water pump. In other words, the impeller is the heart of a water pump, and without it, the entire system can fail. It catches the liquid in its fins and increases its flow by turning. The torque is derived from the pulley and bearings. The effectiveness of a water pump is determined by the impeller’s specifications.

You need to keep in mind its diameter and the number of fins it has. Both these parts decide the amount of pressure produced by the pump. Impellers are crafted using plastic, metal or cast iron.

 

 

How to know a water pump is failing?

 

There are a few factors that can point towards water pump failure in a vehicle:

• leaking coolant
• overheating engine
• smoke from the radiator

If you experience any of the above, chances are that the water pump has failed or is nearing failure. If such a thing happens, you should take your vehicle to a mechanic and get the water pump checked for faults.

Your car’s cooling system is a key element that greatly affects the efficiency of our vehicle. It is made up of different components and uses coolant for a number of purposes: The main purpose is transferring heat and preventing engine damage caused by freezing or boiling. The second purpose is for climate control in the vehicle’s cab during cold ambient temperatures.

It plays an essential role for keeping the engine within operating temperatures, as well as protecting the block thanks to the auxiliary water pump, which circulates coolant throughout the engine and cooling system.

While most vehicles only have a single water pump, some others have a second water pump that will expedite the process, known by the name of auxiliary electric water pump.

But, what is auxiliary water pump? These pumps were first used on diesel vehicles and their initial purpose was to cool the vehicle passenger compartment. And now, auxiliary water pumps are fitted to many modern vehicles, typically located at the rear of the engine.

So let’s get started. This article provides you with all the necessary details you need to know about this type of automotive water pumps.

 

What does the auxiliary electric water pump do?

 

As its name indicates, its main function is to support the vehicle’s cooling system, although its use is largely intended for the comfort of the passenger compartment. It also regulates and distribute the temperature with which the heater is turned on. Regardless of what the thermostat is doing, its main function is to circulate coolant through the engine itself when it is cold.

This water pump is based on the integration of a hydraulic system, an electric motor and also an on-board electronic module. What’s more, noted for being silent and high durable. And also, like the electric water pumps, these do not continuously operate. 

Additionally, more auxiliary water pumps can be added to the vehicle. This will depend on the complexity of the cooling system that the vehicle has.

Thanks to the electrification of vehicles, the auxiliary electric water pumps have led to other utilities such as the cooling of batteries in Hybrid and Electric cars, a current trend in the market.

 

Differences between a primary water pump and an auxiliary water pump

 

An auxiliary water pump differs from the primary water pump of the vehicle in a number of different ways. First of all, it is an electrically controlled motor, rather than the vast majority of water pumps that get its power from a timing belts or accessories. It also provides coolant through the heater core when the engine is not running or the RPM is low.

The auxiliary water pump is not in continuous operation. The BCM (controlling module) will control and regulate the water pump depending on the information obtained. This information is based on:

• Coolant temperature
• Exterior temperatures
• Interior tempeatures
• Engine RPM
• Vehicle speed
• Fan speed

 

 

Common symptoms of a bad or failure auxiliary water pump

On rare occasions, the auxiliary water pump will experience an electrical problem or engine overheating. When a water pump is bad or failing, there are some different signs it comes with. The main reason why these pumps fail is age and wear of the electric motor. If the auxiliary water pump is inoperative, you might notice reduced heater performance at low speeds and at idle, that is: cause specific system temperature inconsistencies.

Common signs include:

• Temperature management with fluctuating heat
• The front Windows defrost does not work
• The heater with no heat at all

Once you notice any of the signs of a bad auxiliary electric water pump, it is recommended to get the problem resolved immediately. In order to anticipate and prevent future problems, it is essential to use a quality product that is the equivalent of the original part.

Your car’s water pump is a very important part of its cooling system. With a failing water pump, your car can be severely damaged by overheating. Your car’s water pump cannot last forever, and it can become unusable if damaged. If this happens, it is significant to replace it as soon as possible to prevent much more damage to your vehicle.

The water pump is responsible for moving water from the radiator through the engine and back. Your car must have a constant flow of coolant from the radiator throughout the engine to keep it cool and at optimum temperature. If the water pump is working properly, your car will maintain a constant operating temperature, and it will run smoothly and get you wherever you want with ease. When signs of a bad water pump in your vehicle appear, it can lead to a host of serious engine problems. 

 

6 signs your water pump is failing ​

 

The water pump is the reason your engine stays cool and your cooling system works well. However, a faulty or damaged water pump can be disastrous for your car. Then, how to know if a water pump is bad? Don’t worry, there are several water pump symptoms that you can quickly diagnose.

 

1. Coolant Leak

 

The water pump has several gaskets that can be damaged or worn out over time. In this case, coolant may leak out and drip under the vehicle. If you notice coolant (in most cases green or red liquid) under the center front of your vehicle, it’s time to check the water pump.

 

Keep learning: Water pump leaking: how to solve this problem

 

2. Engine Overheating

 

The main purpose of a water pump in its life is to run coolant through an engine to cool it down. If the water pump cannot do this, the engine may overheat. Regardless of the cause, engine overheating is not a problem to be solved. Heat problems can cause problems such as cracked cylinder heads, burnt pistons, and damaged head gaskets.

 

3. High Pitched, Harmonic Whining Noises

 

Pulley placement problems often manifest as a high-pitched sound coming from the front of the vehicle. This is because a weakened pulley can create a whirring or howling sound at a fairly high pitch when pulled by the pump. This is usually caused by improper pulley placement or bearing problems inside the pump. Unfortunately, once the bearings in the pump wear out, this is the end of the road for the part, and you will need to look for a replacement water pump.

 

4. Water Pump Rust and Corrosion

 

In many cases, contaminated coolant can cause corrosion of the impeller. And it can also generate rust when the pressure plug is bad and causes bubbles. This will cause the pump to be ineffective in moving the coolant and lead to added damage to all of the cooling system components and may completely damage the vehicle’s engine. Therefore, this is something that we should not overlook.

 

 

5. Steam comes out from under your hood

 

Finally, if you notice steam coming from the front of the engine when driving or stopping, this is an instant sign of the engine overheating. As discussed above, the engine will maintain a constant temperature when the water pump works properly and supplies coolant to a working radiator. If you notice steam that is coming from the front of the engine, you should move to a safe place and contact a mechanic as soon as possible. Never drive a car with an overheated engine.

 

6. Holes or leakage system on the dry side of the water pump

 

Last but not least, you can see the holes in the water pump due to the formation of bubbles at the coolant inlet of the pump. The pressure increases and the bubbles implode and cause harm. Regardless of the condition of your vehicle, your water pump will become obsolete. And over time, the outer seals begin to break and deteriorate. If car owners even check the dry side of the water pump, there could be holes. And this is one of the signs of a bad water pump. For this reason, drivers should take their car to a mechanic as quickly as possible.

 

Why is it important to replace a failing car water pump?

 

The combustion that takes place inside an engine subjects the mechanical parts to very high temperatures, and the water pump is precisely the essential part for the cooling circuit to carry out its function. It goes without saying that when replacing the timing belt, the water pump also deserves special attention.

The operating temperature of the engine is critical for its smooth functioning, and a malfunctioning water pump directly impacts the ability to regulate that temperature. So do not hesitate, and periodically check the proper functioning of your water pump, as it is especially important for the life of your engine and, therefore, of your vehicle.

The engine in your car works best at a high temperature. When the engine is cold, components wear out easily, emits more pollutants, and the engine becomes less efficient. Thus, another important task of the cooling system is to allow the engine to warm up as quickly as possible, and then to maintain a constant engine temperature. The main function of a cooling system is to ensure that the engine runs at its optimum operating temperature. If the cooling system or any part of it fails, it will overheat the engine, which can lead to many serious issues.

Have you ever imagined what would happen if your engine cooling system did not work properly? Overheating can cause cylinder head gaskets to explode and even crack engine blocks if the problem is serious enough. And all this heat must be fought. If the heat cannot be removed from the engine, the pistons are literally welded to the inside of the cylinders. Then you just must throw the engine away and buy a new one. So, you should take care of your engine cooling system and learn how it works.

 

Components of a cooling system

 

Radiator

 

The radiator acts as a heat exchanger for the engine. It is usually made of aluminum and has many small diameter pipes with fins attached to them. Furthermore, it exchanges the heat of the hot water coming from the engine with the ambient air. It also has a drainage plug, an inlet port, a sealed cover, and an outlet port.

 

Water pump

 

When the coolant cools after being in the radiator, the water pump sends the fluid back to the cylinder block, heater core, and cylinder head. Eventually, the liquid enters the radiator again, where it cools down again.

Read more about water pumps here.

 

Thermostat

 

It is a thermostat that acts as a valve for the coolant and only allows it to pass through the radiator when a certain temperature has been exceeded. The thermostat contains paraffin wax, which expands at a certain temperature and opens at that temperature. The cooling system uses a thermostat to regulate the normal operating temperature of the internal combustion engine. When the engine reaches standard operating temperature, the thermostat is triggered. Then the coolant can enter the radiator.

Read more about thermostats here.

 

Other components

 

Freeze Plugs: This is actually a steel plug designed to seal openings in the cylinder block and cylinder heads created during the casting process. In frosty weather, they can pop out if there is no frost protection.

Timing head/cover gasket: Seals major engine parts. Prevents mixing of oil, antifreeze, and cylinder pressure.

Radiator overflow tank: This is a plastic tank that is usually installed next to the radiator and has an inlet connected to the radiator and one overflow hole. This is the same tank that you pour water into before driving.

Hoses: A series of rubber hoses connect the radiator to the engine through which the coolant flows. These hoses can also start leaking after years of use.

How does the cooling system work in a car?

 

To explain how a cooling system works, you must first explain what it does. It’s very simple – the car’s cooling system cools the engine. But cooling this engine can seem like a gigantic task, especially when you consider how much heat a car engine generates. Think about it. The engine of a small car traveling on a highway at 50 miles per hour will generate approximately 4,000 explosions per minute.

Along with all the friction from moving parts, this is a lot of heat that needs to be concentrated in one place. Without an efficient cooling system, the engine will heat up and stop running within minutes. A modern cooling system should ensure the coolness of the car at an ambient temperature of 115 degrees, as well as warmth in the winter weather.

 

What Happens Inside? 

 

The cooling system works by constantly passing coolant through channels in the engine block. Coolant, driven by a water pump, is pushed through the cylinder block. As the solution passes through these channels, it absorbs heat from the engine.

Leaving the engine, this heated fluid enters the radiator, where it is cooled by the air flow entering through the car’s radiator grill. The fluid will cool as it passes through the radiator, returning to the engine again to pick up more engine heat and carry it away.

There is a thermostat between the radiator and engine. Depending on the temperature, the thermostat regulates what happens to the liquid. If the fluid temperature drops below a certain level, the solution bypasses the radiator and is instead directed back to the engine block. The coolant will continue to circulate until it reaches a certain temperature and opens the valve on the thermostat, allowing it to pass through the radiator again for cooling.

It seems that due to the very high engine temperature, the coolant can easily reach its boiling point. However, the system is under pressure to prevent this from happening. When the system is under pressure, it is much more difficult for the coolant to reach its boiling point. Occasionally, however, pressure builds up and must be relieved before it can deflate the hose or gasket. The radiator cap relieves excess pressure and fluid by accumulating in the reserve tank. After the liquid in the storage tank has cooled to an acceptable temperature, it is returned to the cooling system for re-circulation.

A working water pump is vital for the engine; if the water pump is not running, the engine will overheat and stop working, and a water pump replacement will be neeeded.

The water pump is attached directly to the engine block and operates by centrifugal force. If the water pump isn’t working, the coolant will remain stagnant, and the engine will overheat. A modern car engine can withstand slight overheating, but severe overheating can damage it. For the coolant to work properly, it must constantly flow through the engine. Making it work is the job of your car’s water pump.

 

Water pump replacement: Signs

 

There are a signs of a bad water pump that may indicate your vehicle’s water pump is not functioning properly:

1. Leaks: One of the first signs is a coolant leak. The water pump has a drain (weep) hole at the bottom. A small amount of dry coolant residue leakage around the drain is average, but coolant leaking from the drain signifies that the pump is out of order and needs to replace. Car and spare parts manufacturers provide instructions for mechanics about when a water pump is considered to be faulty and needs to be replaced.
2. Inconsistent temperature sensor reading: A fully functional cooling system will keep the temperature sensor or gauge within normal limits at all times. However, a faulty or wrong water pump can cause the temperature gauge needle to fluctuate from normal to hot and vice versa.
3. Noises: In some cars or vehicles, a faulty water pump can cause a rattling or grinding noise, sometimes intermittent. In such cases, the mechanic will need to identify the noise source before shutting off the water pump. For instance, a mechanic may find that the water pump shaft is loose, which means the pump is faulty.
4. Excessive coolant temperature: The most obvious sign of a bad water pump is engine overheating. This is usually indicated by the engine temperature warning light (or wavy line icon) or elevated engine temperature signals on the dashboard.

How to replace a water pump and how much it costs

 

Before learning how to install a water pump in your car, be sure to check the vehicle manufacturer’s recommendations. Each motor design may have its own belt drive system configuration, so follow all specific instructions. Follow these simple steps to install the water pump in your car:

1. Start with a completely cooled engine, then disconnect the negative terminal of the battery.
2. Drain the coolant into the sump by loosening the tap at the bottom of the radiator.
3. Replacement pumps are usually supplied with gaskets required for operation. Refer to your repair manual and get to know the location and type of the pump before starting work.
4. The water pump is sometimes well hidden under the exhaust manifold. Your vehicle repair manual tells you which components you need to remove to get to the water pump. On some engines, it may be necessary to remove the shroud, radiator, and hoses to access the water pump. You may also need to remove the harmonic balancer, pulleys and fans, which needs a special puller.
5. Remove the old water pump. When removing, pay attention to the length of the bolts, as they may not be the same.
6. Before reassembling, make sure all is clean and free of old gasket material and water pump glue. If the mating surfaces are dirty, coolant leaks may occur.
7. Check the water pump installation and visualize the assembly before proceeding.
8. Use silicone RTV water pump gasket if recommended in the repair manual. Take your time with this step, as improper execution can lead to leaks. Use a putty knife or gasket scraper and carefully prepare the veneer surface before proceeding. You don’t want to have a badly installed gasket and have to redo the job to fix any leaks.
9. Install a new pump. Refer to your manufacturer manual for the correct reinstallation sequence. Tighten all bolts to specification.
10. Reinstall any removed components. Refer to your manufacturer manual for the correct way to fill the coolant and coolant mixture. Be sure to vent the system to remove any air pockets that could cause malfunction and overheat.

Keeping your car in good condition does more than just prevent some issues, it also helps keep your vehicle running smoothly and extend its lifespan. So, a regular vehicle maintenance is the key. You certainly don’t have to be an expert, but the information provided below will allow you to learn about vehicle spare parts and become a more informed driver!

 

 

The importance of good vehicle spare parts maintenance

 

Regular maintenance reduces the probability of a car breakdown and, at the same time, extends the vehicle’s life. If there is no proper maintenance of your car parts they can easily get damaged. This is the main reason why you have to take your vehicle to the proper maintenance and also through the proper servicing, you could diagnose the issues of your vehicle before it causes serious damage. In addition, preventive maintenance is cheaper than carrying out a car repair, so you will also be taking care of your pocket.

Not everything can be repaired. Sometimes, to keep your car or vehicle running you need to replace! Vehicle spare parts can be classified into two groups: repairables and consumables.

A good maintenance involves also to know some consumable parts of the vehicle that must be periodically replaced and besides are not repairable.

Did you know? Vehicles have some commodities that have a specific and limited use and have to be replaced after a certain and easily predictable time. Failure and neglect can cause serious damage and that is why, generally, the replacement period is less than one year. Among the most common consumable parts are the following: engine oil, brake pad, coolant, tire, etc. 

There are different factors that will influence the lifetime of our car parts, like the use and type of driving of the vehicle or the reputation and quality of the spare parts. Therefore, it is important to choose only certified manufacturers with extensive experience.

 

 

Some of the most important vehicle spare parts you should know about are:

 

Battery (and alternator)

 

The battery is a critical component. It allows your vehicle to turn on providing a jolt of electricity that is needed to power the engine. In a majority of cars, it will be located under the hood, and you can identify it with the (-) and (+) symbols. Acid stratification and low charge are the most common causes of battery failure. 

Meanwhile, the alternator is what keeps the car’s battery charged while the engine is running.And without the battery, your car isn’t going to turn on. So, you may want to keep that in good condition.

 

Car oil

 

There are many roles that a car engine oil does, its most important role is lubrication. A car engine contains hundreds of moving metallic parts, which would quickly wear out without oil to lubricate them. If there’s too much friction between two mechanical components, they can lock together and cause the engine to stop running. But, how much engine oil does a car need? The amount of engine oil needed will depend on the size of your car’s engine 

If you suspect that your engine is consuming too much oil, you should take your car to a garage to be checked by a mechanic.

Car filters

 

Every car has four main filters: the cabin air filter, oil filter, fuel filter and air filter (engine). The function of all these filters is to enable flows and catch impurities.

You should always choose products that meet the specifications of your vehicle. Incompatible parts will be inefficient and may also fail earlier. It has the same importance when new oil, fuel, or hydraulic filters are being installed, you should always change the corresponding fluid too. Don’t forget it!

Changing your oil and filters will depend on the brand and model of your vehicle, so It’s important to check your owner’s service manual.

 

Tires

 

Your tires are always in contact with the road and will naturally wear down over time. If the tires are very worn or smooth, it will be necessary to change them, otherwise you may notice slipping when driving, especially in winter, so that can cause you to have an accident. It is important that you pick tyres that are well suited for the conditions that you most regularly drive in. After all, tires are what allow you and your vehicle to roll down the road. Take care of your tires, and they will take care of you.

 

Timing belt

It is an often overlooked part of the car but it plays an important and essential role. The timing belt (also known as the cambelt) is the car part connecting the crankshaft to the camshaft. It operates in a perfectly synchronised sequence at maximum efficiency of these parts and controls the opening and closing of the engine’s valves. When a timing belt breaks, it causes damage to the valves and piston and can lead to catastrophic engine failure. So, keep an eye on its condition. A replacement on schedule will greatly reduce the chance of a broken timing belt.

Water pump

 

 

The water pump is vital to the operation of a car engine as it ensures that coolant flows through the cylinder head, radiator, hoses, and cylinder block and maintains the optimum vehicle operating temperature. In other words, It is the heart of the engine cooling system.

A poorly designed water pump can cause overheating of the engine. This can be caused by such factors as incorrect tolerances and poor materials. Once the water pump is damaged, it is really important for you to get a new one for replacement so as to ensure the proper working of your car. Quality matters!
