Thread: squeeky serpentine belt argh!

Had the same problem, went over everything couldn't find the problem, started using belt grip, about two months later the belt snapped, had a old belt laying around put it on lasted about 15 minutes.Checked the tensioner again couldn't find any play in it. Decided to buy a new tensioner any way,
No more noise!

I had a very annoying squeak/screech with my serpentine belt when I bought the vehicle 18 months ago, the tensioner had been replaced about a month before I bought it, but had old belt, so first thing I did was change to a new belt (Gates) and it was even worse , so bought a Dayco upon recommendation, which was no better.

I read on one of the UK LR sites that the tensioner pulley manufacturing tolerances can be such that it does not run true - the way to solve is a 5c coin behind the tensioner where is sits against the block, at the 9 o'clock position as you look at it from the front of the vehicle. Haven't heard a peep out of it since. Might be worth a look for anyone with persistent problems.

DB, in regards to the rough backed belt, is it a Lemforder belt by any chance? I have heard they are very good at staying quiet due to the rough backing instead of shiny.

yep - 5cent piece at 9 oclock - fixed it for me

no funnily enough it was a lemforder i bought when I bought the new tensioner...that made it squeak like a bitch..

the garage actually said to me they are renowned for being really really good belts but they (or the one I had) had a shiny back.. he pulled a new belt off the shelf to show me the difference, and what a difference it was the blet he had put in replace of the new belt bought was so rough on the back it was like it had little pockets everywhere if that makes sense.

the lemoforder is now my emergency belt...incase I ever snap one. I will never be without a belt in the back now after shredding one and having to dead tow home

Ha ha Gold...
Have had a squeeker 300 for about 6 months - gotten good at ignoring it.
Ive tried new belts, old belts, all new bearings - no real change
Then oil, dry lube, talc each worked for a bit then squeeker came back.

Eyeballing the belt everything was true and square, no funny movements, no wear to the tensioner at the spring - but figured whats 5 cents. Just put 5c in at 9oclock and we have silence...

Thankyou to whoever wrote this suggestion !!!!!! I owe you a goldie!

Wish I had tried the 5c trick before replacing my tensioner...
