I have a 1991 deluxe cab pick-up 4WD manual, 4 cyl with a loose belt on the A/C compressor. Can anyone tell me how difficult it is to tighten where it doean't schreech?
There should be an "idler" pulley for the A/C and it's towards the bottom left of the engine bay if you're looking at the motor head on. You'll need a 14mm socket and extension for this one i think. You can probably get to it from underneath. A metric toolset goes far!
also make sure the belt isn't old. if you're in the last quarter of the adjustment on the tensioner, it's time for a new belt.
