Help please. Just replaced the timing belt on my 03 Toyota Tacoma. Had a little trouble but overall went smoothly. I just turned the truck on and it had a rough idle. After awhile the idle started to smooth out, but when running at 2K RPM and above it squeals like I have a super charger on my no super charger V6. Is this normal?

Quick response would be great. Wife has to drive it tomorrow.

Thanks!

No, whining or squealing is not normal. Neither is a rough idle if you just replaced the belt. If it's the same belt, and you put it on the same way as the old one, why do you think it would care and idle roughly?

thanks for that it is still whining a little it has quitted down a little. I was wondering if the belt just needed to be seeted or if there was something wrong with the install it was a new belt from GATES #T271. The vehicle just does not sound the same as it did with the old one that was removed yesterday with 142000 miles on it.

did you replace anything else? tbelt tensioner? t belt idler? they should be replaced at time of tb and so should water pump.
if you hear belt squeel chances are you have a loose accesory belt.

no belt squeel soounds like gear drive whine

mcshaw03

nothing else was replaced it was all checked and all within standerds

was wondering if the whining was a normal for a new install and that it is now quieting down

Did you count the teeth on both belts? Were they both same length? (minus stretch of a fraction of an inch)
I don't like at all the rough idle after changing it. It should not happen if the change was quick and nothing else touched.

no didn't count the teeth on the old part but the new fit right in place and the rough idle went away after about 3 min of tikering and the check engin went out to it was drivin for about 5 miles and sems to run smoth now with a slight whine

Check the the TB guideplate on the crankshaft under the lower TB cover. This guideplate is dish shaped and goes on one way. If it is put on backwards it will dig into the new TB and cause a similar whine. Seen this on a 3.0 one time and the TB was worn down to about 1/2 " wide. Bottom line, redo and check everything and make sure its right.

Obviously, drive belts not properly tensioned will whine a bit..
