So I have a 93 Chevy Blazer K1500 tbi blah blah and it recently began squealing like a stuck pig. I recently did some work on the engine and got a little coolant on the serpentine so I figured out the belt must have glazed over. A dab of lithium grease confirmed indeed its the belt and no amount of scrubbing with a wire brush managed to save this belt so that leads me to the real question.

So I was about to buy a belt from napa or autozone but I have found a way better price online and trying to save as much money as I can i am ready to order a belt but I can not for the life of me figure out which damn belt to order.

I have air conditioning and I'm pretty sure I don't have an air pump and all the belt sizes listed for that model are a little over 96" but I know this blazer and it seems like nothing as simple as ordering the part listed for it so I measured the belt and I got a measurement of about 97.5". Could I have stretched the belt out that much? The wear indicator on the tensioner only shows a little bit of stretch in the belt so this is why I'm worried the 96.16" belt will be too tight a squeeze. The 97.05 is for a blazer with ac and air pump. I've checked all my pulleys and belt routing diagrams and I'm almost positive I don't have an air pump so why would my belt be >97"???

If anyone knows which friggin belt to order then please let me know so I can order a belt online.

I would be oh so thankful.

 

The easiest way I know to handle things like this is to pull your belt off and take it to a parts store tell them you have a modified engine and need to look at the belts and match yours up. They say ok here they are and you search through them until you find one that will work. Then right down the part number and specs on it and go home and order your belt online

 

yeah, that way better price isnt going to help if they send you the wrong one and have to wait for another one. i always bring in parts when i can

 

You don't have an air pump. Buy the belt for a 93 K1500 Blazer with AC. Goodyear or Dayco.

 

If it has any numbers on it you can cross reference it

a actual parts store will have a belt measuring tool if you take the old one with you

make sure you clean the pullys again before installing the new belt
