Water Pump Replacement

Let’s take a moment to discuss water pumps. Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your vehicle from overheating. There are five main components to the cooling system:

-the radiator
-the radiator cap
-the hoses
-the thermostat
-the water pump

The water pump is like the heart of your cooling system, circulating the fluid throughout your vehicle.

A water pump only operates when the engine’s running. Water pump failure is pretty routine. We see it often at Falmouth Motorcar. Some start failing at around 40,000 miles, but most fail by 100,000 miles. Check your owner’s manual or give us a call and we can see when it is recommended.

The water pump either works or it doesn’t, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fail or they begin to leak. It is possible to have a leak from a cracked water pump, but it usually leaks at the gasket where it attaches to the engine.

How can drivers tell when the water pump is failing? If you can hear a low-pitched grinding sound coming from the water pump, it’s got a problem. If you can see coolant in that area, you’ve got a leak.

Some water pumps are driven off the timing belt. They might be under a plastic cover so you can’t see the water pump. Look for coolant on the driveway. If you see some, have us check it out.

Timing belts usually need to be changed around 60,000 miles and the water pump should be changed at the same time. To start with, 90% of the work’s already done with the timing belt change. If a leak develops later, the timing belt will have to be changed again along with the water pump because the belt will have been contaminated by the leaking coolant.
