waterpump installation?
 

Could anyone help me help my friend? He needs to put in a waterpump on his friends 1999 Malibu but isn't sure how big of a job it is going to be. Could anyone tell me how long this should take, is it easy to get to? Or like most of the vehicles these days is he going to have to dismantle half of the front end to get to it?
