I am changing it this weekend.
Took the engine surroundings apart and pump is faulty.
It is not rotating right, seems the bearing on the coolant side has given up.
Glad i changed it before it really broke and messed up my distribution.
I am taking pictures of the replacement, if someone is interested in a how-to-replace-yer-waterpump i can post a how-to later on if you like that.
I was happy to see that the head-gasked repair i did last year is still succesfull, timing chain housing is clean, last year it was full of buttery blubber.
My Alero is holding up, even when i am not so nice to my engine pushing it to it's limits
I am very pleased how everything comes apart, even the exhaust was easy to dissasemble. (props for GM
)
That's a big difference with some european cars, they are sometimes rusted together, won't give in, and everything gets broken.
Well, i will post some more after finishing the job, it takes more time than i thought, GM states 6.3 hours labor for it but it will cost me two whole days.
(haven't got all special equipment here at home so some almost unreachable bolts cost an hour before i get a grip on it) hang on! cheers!
