I don't know off hand but if you go into a car parts store they usually have haynes manuals or you can get at chilton manuals at the library. If you want to ask a mechanic or someone at a car parts store make sure you know the engine size. Likely it says something like 3100 or 3400 or 3800 II meaning 3.1L, 3.4L or 3.8L which are all very common GM engines used in Pontiacs, Oldsmobiles, Buicks, and Chevrolets. Hope this helps, it's a pretty easy answer to get when just about every American mechanic knows these cars in and out.
