1993 2.4 AC belt change?
 
Iím working on changing my belts. The alternator was easy. It had a tensioner bolt just like the manuals show. My AC idler pulley doesnít have a tensioner bolt. I have looked all over on it. Is this one of those things that is odd ball on the 1993?

Tropical cats thanks for the video link. I had watched that one as well as others that show the same tensioner on the AC idler pulley before trying to replace the belts. Mine doesn’t look like that. Wasn’t sure if it was a weird 93 thing. I’m thinking someone replaced the original with something different before I bought the truck.

Didn't see how to do it from my phone. Figured it out using my computer.
I don’t see a tensioner bolt. Am I missing something?

Surely the previous owner deleted it. Mines a 94 and the tensioner is very adjustable. Hope you find the right parts to make it oem AC.


BTW the clutch is not removable gotta buy the whole compressor.

Looks like a spring-loaded tensioner. Slap a big wrench on the hex and swing it inward to release tension.

I’ve never seen one like that before

Not one like that on mine ...


It appears to be: Engine off! Big wrench on the body, loosen mounting bolt to alternator, rotate to engage the desired fine teeth between the two parts of the tensioner, tighten the mounting bolt, recheck belt tightness. No spring.

The clutch IS removable, it's not available separate but it can be removed. I removed mine on my former 93 when the clutch wasn't engaging all the time, I ended up removing one of the shims and than it worked fine.


Have to remove the center bolt than carefully pry the outer clutch off ( or use the tool), than there is a snap ring that must be removed.

it's not a 93 thing, your truck doesn't have the OEM part, my former 93 had the adjuster that is shown in the factory service manual.
