Another Tip. AIR
Pump Belt/Sizing

5:34
PM 7/29/2002

While doing major engine surgery last weekend
we replaced all drive belts while the various pulleys were
off. I was never very happy with my AIR pump belt: it always
sat too high on the pulley and looked as if it was ready to
fly off. It just did not sit right. And the new did also. So I
did some detective work today. That belt is GM-discontinued.
So I had my parts fellow do some investigation. And this is
what we came up with. This may be a Bubba so beware! There are
nuances in belt sizes. Most are 7/16" but some may be 3/8".
Most suppliers go by application (e.g. 1979 Chevrolet) but I
have learned to go by size. I had a 7/16" on the AIR pump.
This evening I went with a 3/8". Look how nicely it fits on
the pulley. Live and learn! (I am not a politically correct
belt numbers person, obviously.)

I use Simple Green (diluted) and a scrub and
tooth brush. Some of us still have the AIR pump on .
