Angry Having issues with ASP pulley and gates A/C belt.

I did some research and found that I was to use a K040378 Gates belt for the A/C. The belt will not fit. Its way too small. The belt that came off was a Gates K040410 and its waaay too big.

This belt is too easy to install for it to be a mistake of mine.

I measured the belts and theres a 1.5" difference in the two. How can the K040378 belt not fit if thats what everyone is using?





What am I missing here???

Just like the diagram shows. I start with the crank then run it under the smaller pulley running across the tensioner and it goes half way on the A/C..

You are pulling down on the tensioner right?

K040410 = 41"
K040378 = 37.8"

Maybe get a belt right in the middle, like a K040390?

The belt goes between the two tensioners,

The tensioners come together to make the belt tight.

Also sometimes the wrong belt gets put into the package. I'd take it back and see how long it really is.

When I was searching for belt part numbers on here, the ones that were supposed to be right were no were close. The boxes I have here in front of me show the A/C belt to be 37.8 and the Large belt to be 70". These are for a 25% underdrive.
