What the Water Pump Does and Symptoms of Failure

Model: (Various brands) Various
Part: Pump

This video is currently unavailable

The water pump maintains the correct operating temperature and regulates heat exchange between the interior and exterior through the radiator. A malfunction can lead to premature wear of mechanical parts, a risk of seizing, and burning of the head gasket.

Inside the pump is the coolant, which lowers the freezing point and raises the boiling point. This captures excess heat and prevents corrosion.

Symptoms of malfunction include frequent increases in engine temperature, coolant leaking outside the pump or onto the ground, and high-pitched, squealing sounds from the engine bay. Replacing the part can be very costly, so do not underestimate the warning signs from your vehicle.

If you do need to replace it, remember to change the thermostat as well.

It only costs a few pounds, but then you won’t have to think about it again.
