The water pump on your Toyota VVTi unit recirculates the cooling fluid through the engine and radiator to keep the system at a certain temperature. However, impurities and and other deposits will eventually make it run inefficiently after a while, so you’ll have to replace it.
In order to perform the operation, you’ll need a 10 mm socket ratchet and the brand new replacement pump according to your engine. Here’s how to do it:
Locate the water pump according to the video bellow
Loosen the drive belt by unscrewing the tensioner’s bolt a bit
Remove the 6 bolts that hold the pump attached to the engine
Take out the pump and its rubber seal
Carefully put the new seal and pump in place and secure the assembly with new bolts
Put the belt back and tighten the tensioner.
