Addicted To Boost Posted January 14, 2008 Report Posted January 14, 2008 This may be kinda a noob question, but my 89 GP SE has an AIR pump and a belt that drives it; I need to change my serpentine belt on the car, but I need to know how to go about getting the AIR pump belt off? Or is there another way to change the serp belt without removing the belt? Thanks in advance Quote
Robby1870 Posted January 15, 2008 Report Posted January 15, 2008 I haven't seen a 5spd 3.1L in a while, but from what I remember, the AIR pump belt is in front of the serpentine belt. You should just loosen the bolts on the pump (I think there is one that is the "adjustment" bolt and will allow you to rotate the pump about the other bolts when loosened) until you can remove the AIR pump belt, then do a normal serpentine belt replacement.

Addicted To Boost Posted January 16, 2008 Author Report Posted January 16, 2008 Take the AIR pump off No. The car runs good and motor is clean, gets killer mileage, why mess with success. Quote
patgizz Posted January 16, 2008 Report Posted January 16, 2008 cause the air pump has nothing to do with mileage or reliability. i vote snip the air pump belt to get the other one off Quote
Crazy K Posted January 16, 2008 Report Posted January 16, 2008 duh!!!! remove the air drive belt. replace the serp belt. leave the air belt off. drive for 1000 miles. see what difference it actually makes. then put it back on if you still want it on. Quote

Addicted To Boost Posted January 22, 2008 Author Report Posted January 22, 2008 I finally had a little bit of free time today, so I got around to doing this. I couldn't for the life of me get the adjuster bolt on the air pump to come loose; I also didn't have good tools to work with at the time and about 10 minutes to get the job done (working in below zero weather sucks ass), so I just snipped the air pump belt and put on the new serp belt. I'll have to replace the air pump belt when its warmer out. What exactly does the air pump do? I've heard that it just injects air into the exhaust, but I'm not really sure myself. Quote
1990lumina Posted January 22, 2008 Report Posted January 22, 2008 Ya I think it added air into the catalytic converter or something to help with emissions. Quote
slick Posted January 22, 2008 Report Posted January 22, 2008 That's exactly all that it does, it pumps air into the exhaust, helps emissions. Probably actually helps lean out the exhaust gas as well, but who knows. Quote
