Changing The Fanbelt?

[CoBeerToad]

I'm having a hell of time replacing my belt. I put the old one on, and it went on fairly easily. But the new one... Wow. It just don't want to go on. I tried saving the lower idler pulley for last, and I've tried saving the A/C for last.

Do you think heat expands these much? The new belt has been sitting outside for a few days. I'm thinking about putting it in the microwave!

It's a Dayco 5060833. I checked that first.

To put the belt on you have to loosen the tensioner by turning it clockwise about 45-90 degrees. If it freely turns and tension does not slack then reach behind with a 15 mm wrench and hold the nut in place while you tighten the tensioner. Then try again 45-90 degrees clock wise. Install the lower idler/tensioner last I think. The belts should not change with heat and should be the same length.
