Squeeling Serpentine Belt

bernieg

Overdrive!
When i first start the Landy the Serpentine belt makes a hell of a squeeling noise for the first 10 minutes or so and then it stops and everything is fine.

I have tried another belt, have even changed the tensioner. Did a test with an old belt.....sprayed a lubricant on the belt while it was making the noise, and it stopped.

Any idea's....its driving me mad :shake:
 
Mine had too thin a belt fitted, and was also cracke din places.. Fitted with a fatter belt and all worked fine.
 
I have found that a tiny bit of talc on the belt stops it for about a month, a new belt stops it for a bit longer but it usually comes back.
You need to check that the bearing in the tensioner pulley is ok though cos that can cause this symptom
 
Just remembered!
Mate of mine had an old Datsun with a squeeling belt. Tried a new belt, even tried a new pulley but couldn't stop it.
Finally in desperation (suspect he was drunk at the time) he put golden syrup on it (yes)..........

Cured it for months!!!
Re-anointed it every few months and never had a problem again.:D
 
I have this same issue with my Discovery. Squeals & chirps when started from cold, but once warm, the noise disappears.

One guy I talked to reckoned it was wax/grease build up in the belt grooves, that squeal when the material is cold & solid. Once warmed up the gundge conforms to the pulley grooves & therefore stops squealing...sounds reasonable enough??

All I know is that I have never been able to get rid of the noise for long either!

Cheers
 
Land Rover released softer "anti squeal" belts towards the end of the TDi's life. Two part numbers, PQS000030 was the equivalent to ERR3287 and PQS000040 the equivalent to ERR5911. It did seem to cure a few squealers but being softer didn't last as long as the "proper" belt. Before they came out we always got a Gates brand belt from the local factors.
 
Have had enough of the squeel, have decided as a first step to take off all pulleys and give them a damn good clean, get all the crap out of the grooves.

Any idea's what would be the best stuff to clean/soak them in, someone mentioned parafin....any other idea's

Cheers

Brake cleaner or even petrol, but be careful! You need some sort of solvent to dissolve the grease and something that will evaporate to leave it clean.

Talc or chalk powder is used in the trade to quieten belts but only a short term fix.

Dont use commercial belt dressing, its sticky stuff and makes the problem worse! Don't ask how I know that!:eek:

Probably spray on degreaser and a tooth brush. Wouldn't take the pullies off though just clean em in situ.
 
I tiny bit of silicone grease on the grooves of the belt works a treat and lasts a good few months I've found :)

Thank Man in Hat!
Did that - Sorted!!

Just a very small amount of silicone grease applied to the working side of the belt. Just waiting to see how long it lasts now:rolleyes:
