how to replace the water pump?

Hello,

The water pump can the replaced by using simple hand tools.
In most cases you will need to raise the car up using a floor jack and supporting it with jack stands.
Its also a good idea to use latex gloves and wear safety glasses.
Be sure that the engine is cool and the car on level ground.
