I need the engine diagram for 2001 mercury cougar. The serpentine belt broke after one of the pulleys locked up. I am trying to figure out what that pulley is associated with. I suspect it may be the water pump.
4 cyl or v 6?
2.5L V-6 with air conditioning built 01/99 onwards
The water pump pully does not usually fail by locking up. It is more common for the tensioner to give problems. Try turning each pulley by hand - with no belt they should all turn rather easily (not counting the crankshaft pulley.) There should be a decal on the underside of the hood showing the routing of the belt and identifying the components.
