"When you remove the belt, can you spin every pulley by hand freely? Is your belt tensioner spring stretched beyond spec?"

I don't know, but the tensioner spring is what came on the car when I bought it.

As far as the belt...



My alternator is a valeo. ( I found that out after I ordered the bosch voltage regulator)

I just found the receipt for the belt and pulley that was on there from 2014 from pelican parts (did not squak for a few years). had I known that I would not have replaced the pulley, trying to think if I threw the pulley out or not... .
Sales slip (pelican parts) says 6k x 2140 010-997-79-92
The one I have on the car says 6PK 2140

I looked online and they are the same as far as I can tell.

I measure the cooling pump pulley and it is 157 MM.

It sounds like I have the correct belt.

I cleaned the gunk out of the pulley grooves before installing the new one. Would that make a difference?
