thrown drive belt!

**godless-phoenix** · 03-18-2010, 08:17 AM

so i replaced my drive belts about 2 weeks ago, and yesterday my belt came off 2 times in a row, luckily i had pulled right over before my engine overheated, and had a wrench to put it back on...what couldve cause this? is my tensioner pulley going bad or is this "normal"...im 110% sure i have the right size belts...any ideas?

Probably your tensioner if your sure you have the right belt. Myself and many others have bought the Katech solid tensioner, it works great. Ive never thrown a belt or had one walk since installing.

Check the tensioner and then check all the other pulleys. I had a water pump that the shaft bearing wore and it wobbled enough to throw the belt. So I'd check all the other pulleys too.

id say pop the hood, crank it up, and have someone rev on it a little..see if you can see where its coming off at

Did you just put a UD crank pulley on your car?

no i did not, all the pulleys are still stock...i popped the hood and started the car and revved the engine from the throttle cable and it looks a little wobbly, but nothing to bad...the belt didnt fall off, so i dunno...

the water pump is pretty new, its a little over a year old...

The most likely cause is a worn belt tensioner.

ill probably end up doing this, thanx ;P its not cool when you just get on the freeway and your bet falls off and you have no power steering and the car starts over heating

I've also had the Katech belt tensioner on my car over 5yrs, and I've never thrown a belt since.

I think CompCam also has a manual belt tensioner to.

i remember with the previous belt it was half way off the tensioner pulley one day and i had to slip it back on...so that could be where its falling off
