How to replace the water pump in your car

Your car’s engine produces a great amount of heat when in use, enough to cause serious damage without a proper cooling system. The water pump is the key component involved in preventing overheating, but what can you do when it breaks and can you repair it yourself?

The water pump is a critical component of your car’s engine – by cycling coolant throughout the motor, excess heat is absorbed and then dissipated through the radiator. If your car is regularly overheating, or if you can see coolant pooling under your vehicle after you park, this may indicate that the water pump is failing. If you suspect that your water pump has become a problem, replacing it should become a priority task, before engine overheating causes damage to more expensive components. Replacement of the water pump can be a daunting task, and the apparent complexity may discourage some car owners. Should you decide to buy a water pump on the Web and perform your own repairs, however, you will save a lot of money in labour fees.

Should I replace my own water pump?

The steps required to replace a car’s water pump vary slightly for each vehicle model, but they generally involve the removal of several other engine components to allow access to the pump, often including the cooling fan and cover, hoses and alternator.

While this may sound complicated, with a little care and patience even novice home mechanics can complete the job successfully. Buying a water pump on the Web and replacing it yourself can save you a considerable amount of money, but improper reinstallation of these components can cause serious damage to your vehicle’s engine. If you’re feeling squeamish about the job, it may be worth the extra money to take your car to a licensed mechanic.

Replacing the pump

Even experienced home mechanics will want to have their car’s service manual on hand before performing a water pump replacement. The manual will contain instructions and helpful tips for the removal of the pump, as well as the various components blocking your access to it.

First, disconnect the negative terminal from your vehicle’s battery. Once done, find the drain valve near the bottom of your radiator and drain the coolant into a plastic container. Keep in mind that this coolant likely contains antifreeze and is toxic to humans and animals, and so it needs to be carefully disposed. With the coolant drained, follow your service manual’s instructions to remove the pump and replace it with the new component. Ensure you have closed the drainage valve, replace the components you removed, and refill the radiator with the proper mixture of water and antifreeze before restarting your vehicle. Monitor your engine temperature closely to ensure the coolant is being properly distributed.
