Among the most common causes of water pump damage are leaks, improper use of sealant, damage from improper use of coolant (cavitation damage) and corrosion.

These breakdowns can seem sudden and unpredictable, but the truth is that it is the lack of preventive maintenance that speeds up water pump failure in most cases. Although water pumps wear over time, certain negligent factors are mostly responsible for speeding up this process.

In today’s article we focus on the keys that will extend the service life of the water pump.



How a good water pump maintenance will extend its useful life


When speaking about a durable and reliable water pump, there are two aspects that can certainly not be disregarded: the first one concerns water pump fitting and quality; the second one is all about meticulous and regular pump maintenance.

The benefits of optimum water pump maintenance go beyond fault detection and provide a huge opportunity to anticipate breakdowns, prevent pump corrosion and avoid system failures that would otherwise result in operating expenses related to repairs and the purchase of newly required equipment.


Maintenance on a regular basis


Preventive, rather than corrective maintenance allows the solving of existing faults before these affect pump performances. Both users and experts must be continuously aware of any inefficiency sign.

From high-pitched or screeching sounds coming from the front of the engine to cavitation and bearing noises, vibrations, decreased water flow, seal chamber leakage or clogging. 

This should be done by a qualified professional with the skills, experience, and tools necessary to properly inspect the part, perform engine inspections, and adjust, replace, or repair any components that are not performing as intended.

Specialists should advise end users to dig a little deeper into the condition of their water pump by checking the bracket, seals, motor couplings and bearings, making any necessary adjustments and/or repairs.

About frequency of this maintenance and its specific guidelines, Dolz recommends always following the owner’s manual with every manufacturer’s service information. 


Accurately coolant management


The fact that water pumps are often referred to as coolant pumps shows the importance that this liquid has for its functioning. While coolant degrades over time, users sometimes add water to it in a failed attempt to save money and time. 

The reality is that contaminated or incompatible coolant largely increases the chances of corrosion inside the water pump. Manufacturers use different materials for gaskets on water pumps, so verifying that the coolant introduced previously is the right type and emptying it/filling it on schedule will ensure a long-life water pump.


Replace both, water pump and distribution


When maintaining the distribution of our vehicle, we must think not only about the primary elements such as the chain or the belt but also about all the elements, including the water pump, that are part of it.

Changing the water pump or the timing belt are two of the most common operations in a mechanical workshop. For this reason, from Industrias Dolz we recommend carrying out this repair in a single intervention and that it helps the optimal coupling of the components that prevent their premature aging and possible damage to the pump bearing. In this way, we carry out a complete and long-lasting service.

It is important to carry out this operation correctly and safely, since if the belt is not replaced as it touches and becomes too tight, it will cause an extra effort in the rotation in such a way that the pump shaft will gradually give way, causing a fluid leakage and even producing chafing on the propeller blades.


Dismantling of the water pump


It is important to never under-estimate the degree that water pump impeller and housing design contributes to water pump efficiency. Most of the wear that occurs on a water pump is on the internal parts of the unit and therefore, can’t be seen until opened up. 

By removing, inspecting, and cleaning individually all auxiliary and core devices, experts can accurately check for wear at central parts and ensure an optimum operating condition.



4 extra tips to to extend the life of your pump


Taking proper care of your pump is essential to ensure its longevity and efficient operation. By implementing a few simple practices, you can significantly extend the life of your pump. Here are four tips to help you keep your pump in optimal condition:

  1. Lubricate the moving parts of your pump according to the manufacturer’s guidelines.
  2. Regularly clean and inspect the intake filters.
  3. Shield your pump from extreme temperatures, excessive moisture, and harsh environments.
  4. Pay attention to the operating conditions of your pump, such as temperature, pressure, and fluid levels.

In conclusion, regular water pump maintenance is essential for optimal performance and longevity. By implementing a proactive approach and following the recommended maintenance practices, you can ensure that your water pump operates smoothly and efficiently. Remember to schedule regular inspections, clean and lubricate the pump as needed, and monitor its operating conditions.

Taking care of your water pump will not only extend its lifespan but also contribute to the overall reliability of your system. Don’t overlook the importance of water pump maintenance, as it plays a crucial role in the smooth functioning of your equipment and prevents costly breakdowns. Prioritize maintenance, and your water pump will continue to serve you reliably for years to come.
