My belt has almost come off the past two events I've done, so I'm going to put a C6 tensioner on because of the higher sides. I noticed that NAPA has the whole assembly or just the pulley. Would the C6 pulley directly mount up to the C5 assembly, or do I just need to buy the whole C6 assembly. This is for a 2003 z06.

Thanks,
Will

I'm not sure, it seems to me the pullies (sp) should be interchangeable, if napa has both just line them side by side.

My new favorite belt is the Gatorback, just look at one and you will see why, a stout belt if ever there was one.

Final thing is that sometimes it's the spring tensioner itself rather than the pully.

Aftermarket tensioners can be preset for the tension you want on the belt and don't "move around" like the spring loaded ones.

Put a laser on the pullies to ensure they all line up.

I would get the entire assembly for the reason stated above (so you know the spring is good) - $50 - Gates 38328 Belt Tensioner Assembly (from Amazon).

Why take a chance, those spings get soft.

A Katech tensioner will fix that problem.

Have you had any issues, at the track, with your belt after installing the Gates?

Hey Jason what's the correct torque to put on your tensioner for correct belt tension ?

I have a Katech tensioner on mine and have never had any problems. Instructions say to set tension to 25ft-lbs.

I have this item on my car and I am very happy with it.

I put a C6 on my C5 like 4 years ago ... not jumped a belt since :-)

Mine and a couple of others with whom I run are the best fix. Forget the whole spring setup on the OEM. Once you adjust the pressure on the belt and tighten the bolt it is there for the duration!

Also, several of us have clutch packs so when the engine revs quickly, it revs QUICKLY! Belt stays in place with the Katech.

...this...I used to watch my tensioner at idle and just revving the car and it made me nervous. The Katech tensioner has done it for me!
