Default Changing waterpump

I´m a little bit of a rookie. Does anyone knows how to change the waterpump in an c4 1990? Is it a hard thing to do?

Not that big of a deal. Just get the belt out of the way and the intake then you simple unbolt the pully then the pump and then do it in reverse to bolt on. I would change the thermastat also with a lower temp to help on cooling. I would wash the front of the engine down first to get all the crud out if it should need it .
Good Luck wro87

Wasn't too bad of a job. But I did it when I was replacing my intake manifold gaskets. One of those while I'm at it deals.

What pump are you going to put on?
