dragonwingblazer · 10-11-2009, 09:29 AM

can you bypass the air pump on an 88 blazer 4x4 ?? im picking up a new set of front pads and rear shoes for my blazer later on today for a desperatly needed brake job and planning on picking up a ac delete belt while im at it, the air pump doesnt appear to create any vacume anyways and i have gotten all the vacum i need T-ing off of the TBI lines so is it really nessesary? if not then does anybody know the part # for the ac and air pump delete belt?
thanks

The air pump doesn't create vacuum, it injects air into the exhaust.

If you really want to bypass the air pump, you'll need to measure the length and then try a belt or three to get the one that fits best.

There are already threads discussing this very subject. I know for a fact one is on the front page of this section right now.

well first off i didnt realize it wasnt supposed to creat vacum i just assumed so since there is a vacum line run to it, i guess that explains why i couldnt get anything vacum controlled to work with it lol.
neo i didnt know it is a smog pump so i didnt know that thread on this page was about the same thing sorry

Well the correct name is A.I.R. pump, but it goes by many names.

Cheap and quick bypass of AIR (+ "polish supercharger"

).
If your AIR valve is shot (pricey I believe to get a new one), maybe bypass it the cheap and easy way and leave the orig belt.

Hey joed, what is the part number for the belt on your alt/ air pump?

Sorry, I'm in Idaho thru this weekend, and then Las Vegas after that. If you don't already have the answer you need I can check when I get back.
