Water pumps have a long service interval, but this often means that car owners underestimate the eventual need for a new water pump. Although water pumps wear over time, certain negligent factors are mostly responsible for speeding up this process.

Water pumps and timing belts have similar lifespans. Which is why Dolz highly recommends replacing both at the same time. This not only ensures efficient and safe maintenance, but it also incurs labour costs savings and a shorter period of non-use. 

How long does a car water pump last?

When considering a durable and reliable water pump, there are two factors that play the biggest role in ensuring a water pump’s long life: 

1. Water pump fitting and quality. 
2. Cooling system maintenance.

Go deeper: Failing car water pump: Signs

Specific water pump lifespans vary depending on the vehicle’s model and on its type of cooling system. Firstly, it is highly advisable to find a reliable partner before having to replace the last water pump, and secondly, to follow the recommendations specified in the car owner’s manual when installing the water pump.

Furthermore, the urge for a brand-new water pump will largely depend on driver practices throughout the years. If preventive maintenance and thorough care of the vehicle’s cooling system are taken seriously, a quality water pump can last up to 100.000 miles, again, depending on the model.

Is a new water pump needed? – Signs

Among the most common causes of water pump damage are leaks, improper use of sealant, damage from improper use of coolant causing cavitation damage, and corrosion. Most of the wear occurs inside the unit, which is why oftenly it cannot be seen until opened.

Regular maintenance should include the dismantling of the water pump to accurately check for wear at central parts. However, there are several apparent signs of malfunctioning. For you to be able to spot any of these, here is a list of the 5 most common water pump failure symptoms explained:

Coolant leaks

Water pump leaking is one of the most evident and common indications of pump failure, making it a clear sign that it’s time to replace it for a new one. Coolant leaks represent themselves as a puddle of coloured coolant (usually green, orange or red) on the ground, right under the parked vehicle.

This happens because the coolant is stored in the pump using a series of gaskets and seals. Once one of these parts wears out, loosens or cracks, the coolant will eventually leak outside of the engine.

If this is the case, we suggest you to drive your vehicle as soon as possible to your closest workshop, as it can still mean a relatively easy and minor fix.

Whining noises

If you hear a high-pitched whining noise that comes from the front of your vehicle while accelerating, it might be a sign that your water pump is dying. The pump needs pulley belts and bearings to function, and if one of these components remain to loose or are worn out, it will make a sound commonly described as harmonic buzzing. 

In many cases, the belt can be component responsible for this sound. Having it replaced along with your vehicle’s maintenance schedule will keep you safe from more serious damage.

Temperature rises

A dying water pump is unable to circulate coolant through the vehicle’s engine and, as a result, the engine will overheat or run at unstable temperatures. If the engine gets too hot, the chance of serious damage is extremely high. 

Overheating can strongly damage the pistons, cylinders, and the engine’s head gasket, potentially resulting in engine breakdown. So, keep an eye on the temperature gauge and, if there is a considerable rise on temperature, take it immediately for inspection or it might end up not being repairable.

Surfacing rust and corrosion

Air seeping through a defective pressure cap, non-compatible or dirty engine coolant, mineral build-up, and even age can corrode your vehicle’s water pump. Rust and corrosion on the pump’s surfaces make the pump unable to move the coolant around.

Rust or tiny holes on the water pump’s surface will eventually damage the water pump impellers, the joint between the block and the pump and reduce its efficiency.

When checking the need for a new water pump, pop up your hood and look out for any signs of rust and corrosion on the pump’s exterior. If these show up, it is time to carry out a water pump replacement, as a corroded or damaged one will not properly operate.

It is a system that aims to alter the opening and closing time of the air intake valves (or exhaust gases) so that the optimum amount of air for the process enters the cylinders. This is possible by a phaser located on the camshaft head called Variable Valve Timing (VVT) System.

Keep reading to find out in more detail how this system works and what it is made of.

Variable Valve Timing: Purpose and operation

As a rule, when more revolutions our engine has, more air is needed by cylinders. That’s where variable valve timing comes in. Its main function is to modify the phase angles of the distribution diagram, adjusting the camshaft according to the needs of the moment.

This VVT system is controlled by the ECU, the electronic control unit that regulates the engine and is responsible for activating this gear through the flow of engine oil.

Oil pressure is sent through the VVT gear to fill up cavities to advance or retard timing. Filling the VVT ​​gear with oil unlocks its stationary pin and makes it two independent rotating parts, causing angular displacement between the input (chain) and output (camshaft), advancing, or retarding the timing.

Keep reading: The different timing chain systems

To obtain the maximum efficiency of the engine, the valves must open and close depending on the revolutions per minute at which it is turning, and this is only possible if we have a variable timing.

There are different types of timing that have unique characteristics, the main difference being in the placement of the camshaft. Depending on the engine, VVT configurations are differentiated and can be run only on the intake valves or on both camshafts.

The two main ones, when it comes to varying the distribution, are:

1. Variation of the valve lift, varying the advance and closure of the valve at the same time.
2. Displacement of the camshaft with respect to the crankshaft.

Advantages of Variable Valve Timing (VVT)

Chain drives can transmit large loads on long and short distances. These systems allow to use the optimal opening and closing time of the valves in any engine situation. Therefore, the importance of the VVT lies in the fact that its proper use directly improves the performance of our vehicle’s engine, optimizes thermal management, and provides a better fuel economy.

The main benefits of this system include:

• Improved efficiency, increased torque, and power: The variable valve timing system allows higher RPM to be achieved, and consequently greater engine power.
• More precise engine timing: It allows minute and precise control of the internal valves (opening and closing) of the engine while driving, therefore it will also obtain an increased engine lifespan.

• Reduction of fuel consumption: Thanks to this effective management of the engine valves, the VVT allows a smoother idle offering better fuel consumption as well as lower carbon emissions.
• Better fuel economy: By having a greater direction and control of the gases, the system performs a recirculation that can reduce emissions.

Variable Valve Timing System: Main components

The main elements of a variable valve timing that come into action to obtain a variable synchronization are:

• ECU (Engine Control Unit)
• Sensors
• VVT Camshaft adjuster consisting of stator, rotor, vanes and locking element
• Camshafts
• Solenoid valves
• Oil
• Timing chain adjuster

Because of the importance of lubrication throughout the variable valve timing system, monitoring oil levels and condition will be essential to keeping all parts in top condition and getting the best possible engine performance. This action must be carried out in accordance with the vehicle manufacturer’s recommendations.

VVL / VVEL / VVTL: Main differences

VVL, VVEL, and VVTL are all abbreviations for technologies that involve altering the lift of engine valves for improved performance. VVL stands for “Variable Valve Lift”, VVEL stands for “Variable Valve Event and Lift”, and VVTL stands for “Variable Valve Timing and Lift.”

In particular, VVTL is an advanced supporting system that allows for precise control of valve lift. In modern engines, the VVL system is often combined with Variable Valve Timing (VVT) systems to achieve even greater performance improvements.

Moreover, various manufacturers utilize proprietary abbreviations for their Variable Valve Timing (VVT) systems, including:

In recent years, automotive technology has been constantly evolving, however, the way of driving has remained unchanged. For this reason, eco-driving or sustainable driving comes to balance this situation, providing a new driving style in accordance with modern technologies.

Benefits of Sustainable Driving

More efficient driving contributes to reducing fuel consumption, polluting emissions and also helps to achieve more environmentally friendly mobility.

Therefore, adopting good driving practices offers many benefits for the vehicle, the owner, and the environment. Some of the main points are:

• Fuel consumption reductions: greater efficiency in vehicle consumption is associated with cost savings and a reduction in polluting emissions into the atmosphere.
• Reduction of maintenance costs: more efficient and eco-driving also entails a reduction in maintenance costs.
• Reduction of CO2 emissions: efficient driving also entails a reduction of CO2 emissions and other pollutants into the environment.

Best Practices for Improving Consumption Efficiency and Achieve Sustainable Driving

Carrying an efficient consumption in your vehicle will be possible with a very simple precautions to put into practice:

1.Follow a Scheduled Maintenance.

Checking the oil, engine settings, and possible parts wear will not only help maximize the life and performance of your vehicle, it will also improve fuel efficiency.

Carrying out a regular vehicle maintenance is essential to ensure a balance between the good condition of your car and its emissions. A well-maintained car engine is a more efficient engine, which reduces emissions.

But, although the engine is the heart of our vehicle, we must not overlook elements such as the tires. Checking your pressure and condition will ensure proper performance. Otherwise, under inflated tires will increase vehicle’s drag resulting in higher fuel consumption due to the need to generate more power to move.

2. Turn off your ignition during prolonged stops (more than 60 seconds).

More and more vehicles are equipped with the Start and Stop system for greater efficiency, reducing CO2 emissions and fuel consumption up to 5% according to the European driving cycle.

However, if your vehicle does not have it, it is highly recommended to turn off the ignition at stops longer than 60 seconds because if the engine is running, it is consuming fuel. The engine doesn’t care if the car is in gear and moving or sitting still and idling.

3.Always carry out the driving with anticipation and foresight.

Try to have a smooth ride ahead of time to avoid sudden braking or unnecessary maneuvers. This will make your driving safer and help reduce emissions.

Proactive driving aims to anticipate possible hazards and take action to reduce, minimize or avoid danger before it can occur.

DOLZ, committed to Sustainability and the Environment

In a sector in which caring for the environment occupies a more and more relevant place, it is essential to acquire a commitment to the environment that surrounds us. At Dolz we are committed to protecting and improving the environment, being one of the fundamental axes of our Corporate Social Responsibility Plan.

For this reason, we are certified with the  ISO 14001:2015 SGA – Environmental Management System  at our plant in Castellón (Spain), which has facilities of 25,000 m2. Added to ISO 9001 Quality Management Systems, which the manufacturing plant also has.

Both standards are world benchmarks on environmental and quality management.

ISO 14001:2015 Environmental Management System Standard

One of the main benefits of implementing an Environmental Management System based on ISO 14001 international standard is obtaining maximum rationality in production processes, in relation to conservation, improvement and protection of the environment. 

This international standard, dedicated to environmental management, is responsible for the company (regardless of its size and / or sector) not only taking into account the impacts caused on the environment but also achieving continuous improvement regarding the minimization of the environmental impact of its activity. For this reason, it allows to adopt a perspective and management of life cycle of the products, activities and services provided and thus achieve a great control of the ecological impact.

Environmental management is a key function that entails a commitment to the conservation of the environment, promoting a more efficient use of raw materials, waste management and environmental risks and also not contributing to the production of new non-recoverable waste.
