serpentine belt

[nmlax39]

when installing the serpentine belt is it supposed to go on easily after loosening the tensioner because i was trying to put a new belt on and i took the tension off and the belt wouldnt fit on all the pulleys. could the belt be too short or am i doing something wrong

I'm assuming your installing the belt as it is shown on the diagram sticker located in front of the radiator. If you are, then the belt is for the non air conditioned Explorer and yours has air conditioning.

The tensioner must be turned all the way back. IIRC it can be a little difficult to get it onto the last pulley still, it's easiest to get it on a smooth pulley.

Otherwise it could be too short.

Also ..... are you certain that you have the correct belt for your application?

When we rebuilt the motor for our X I found out that there were actually two sizes of belts for th 1991 explorer. I had no idea, and never had someone ask me if I needed the short or the long belt.

I've had belts that would barely fit, I had to pull the tensioner all the way to get it on.

What number is on your belt that won't fit and what number is on your old belt?

There's two sizes besides just A/C and non A/C?

Thats what I told the parts guy, but he showed me his book where it showed two different sized belts for a 1991 with a/c.. The only thing I can think of is that the 1991 could have a different bracket somewhere compared to a 1992+.

Huh. That is weird.

I guess that would be one thing to check out here then.

Wasn't there two different AC compressors made for it?
