for all you 02-03 owners....belt tensioner TSB (please read)

[CharmCityES]

for us 02-03 owners,
if you notice a slight belt squeak upon startup (esp when cold), there is an issue with your belt tensioner, and it should be replaced with the updated version that toyota has released as a fix for the issue
i replaced mine today and the squeal at startup is gone....relativly easy fix, and the part ran me about 90 bucks from my dealer (employee discount )
heres the TSB

Thanks for posting.

Just replaced the belt, but no issues with squeak upon start-up.

Good post. My VIN doesn't fall under those though... and I don't have a problem with my drive belt. *shrug* Haha.

[johnnyzee]

yah, i get this exact problem, thanks for the post. Happens once in a while when temps go below 0 (the screetch when starting it up). It lasts about a second, never bothered dealing with it and happened too rarely).

As for the rattles I hear from the motor who knows. It could be this or that intake manifold TSB someone in here referred to. I just hate how everything seems to screw up AFTER warranty. It's like the shit was made to fukk up on a timer.

We just purchased an 03 Camry with the V6. Is this the 2AZ–FE engine because we get the startup belt squeal also.

Thanks !

No. The 2AZ-FE is the 2.4L I-4. The V-6 you got is the 1MZ-FE (assuming you have the 3.0L version). If you have the rarer 3.3L engine (SE only, IIRC), then its the 3MZ-FE.

[Idoktr]

we have the 3.0. So what is the start up squeal?

Probably just an old, worn belt. How many miles? By now, it may just be drying out and ready to be replaced. Not a biggie if that's all it is.

i'd like to thank the noobie for searching.
