Find out how your car's water pump works

Nico Louw, Technical Editor at CAR Magazine explains how the water pump in your car works.

If we think about the energy that is in the fuel which we out in our car, a third of that energy gets converted into heat - only a third of that energy gets to the wheels - and that heat needs to be expelled to the atmosphere to protect the engine.

Nico Louw, Technical Editor at CAR Magazine

And to do that, you have a cooling circuit which uses water involving a radiator and a water pump.

You need a water pump to circulate the water through the engine and then through the radiator, to allow it to be expelled to the atmosphere.

In older models, the mechanical water pump is driven by a cambelt.

He explains why when your car goes in for a cambelt change, the mechanic often suggests changing the water pump - usually at a 100 000km service interval.

If you see drops of water falling underneath your car, it's a telltale sign that the seals on your water pump are gone and need replacement
