Here is a link to our web site that has a complete belt break down chart of all sizes we use. Every pulley combo, direct drive too!

I hope that makes things easier for everyone, if you have a belt length combo we did not post, please do not hesitate to post in this thread to help others.

And our belt installation video. Top or bottom installation.

I run a 2.75/10% OD 10 rib and have a 100535 on my car.

My belt sizes have never lined up with what ECS suggest so I think this is a great starting point, but may not be an end all guide. I swear there is difference in water pump sizes on some cars.

DOUG @ ECS

There is a difference from aftermarket water pump bell's. The manual aftermarket pumps are usually smaller.

This is great info

I agree with Unreal...I'm using 1 size smaller than suggested.

3.33 upper 10% OD k080915??

I have the same pulley, 10% OD and belt also. Perfect fit.

Ordered a bando 533. Mine has too much slack.
