How do you replace the water pump on a 1991 Pontiac Sunbird 2.0L 4 cylinder?
I done mine recently.......Wholy Crap.....Pay someone to do it.
The water pump is part of the timing belt, What a job! you may even have to lift the engine a bit so it will clear the frame, when taking it out.
I got mine all back together with a new pump, but it idles rough now as I got the timing belt off a bit.
Really......Pay a professional , its worth it.
