Outer Limits 4x4 Board

Having got the tensioner and fan belt replaced i was thinking it would be the end of my noicy belt problem, yep that was all good for about 2 months but now when the car is cold the squel has come back and stays untill the car is warm, anyone else had this problem? solutions or any ideas?

unfortunately some belts squeel. try spraying belt grip on it, a quik fix but only lasts about 1-2 months then sray again.

I think you'll find its still squeaks with the belt OFF.

Yeah I had the same problem with my 99 TD42T but once I changed the tensioner it was fine.

As pointed out maybe you should take off all the belts and see if that stops the squeel. Then if so slowly re introduce each belt until you have found the offending pulley

i have the same problem in mine i think its one of the tensioners.. just need to workout which one..

check the clutch on the alternator pulley they wear out and squeak . Take the belt off and spin the pulley .

Are you sure it is not the exhaust manifold gasket?

Don't you mean the aircon compressor?

Never seen an alternator with a pulley clutch

The alternator has one on the 3.0. They can be replaced with solid units for a lot less $$$ than the OEM one.

If it has a small idler pully, about 30mm diameter, some times the bearings go dry or need more lube. This will make it sound like a supercharger until it frees up. It runs on the back of the belt and is toward the bottom of the crank case on the LHS of the TD42.

thanks for the replys guys, im getting it checked out on thuresday and ill let you know what it ends up being

A lot of the later model eauropean cars have clutches on the alternators too. I have replaced several of them and they are bloody expensive. Last one i had to replace the whole alternator and it was 1100 just for the alternator

I have had three belts and pullies replaced under warranty and still it squeals. Going back in next week....

Spray wd40 on each belt one at a time to see if it stops. That will prove what belt it is (wd40 will evap)
If no change then its a bearing somewhere.

old man went through these dramas with his 3 litre.

belt grip on the multi v belt is a very bad idea, makes them squeel like hell.

i think his solution was a new alternator bearing and a genuine belt, had nothing but dramas with aftermarket belts, about 3 of the things in 30K

I think WD 40 will cause the belts to fail
Hard soap was the old way

thanks for all the replys guys, im put it down to the weather, last week it was freezing and wet so it was making a squiel and this week its been warm all the time and not even a hint of noice.

Just a tip when it comes to 'V' belts and cars .. dont use raw edge cog belts as they are not designed for the enviroment found under the bonnet .. they will squeal once the pollutants work there way into the edge of the belt .. and the best way to find which belt is sqealing is to use a hard soap .. and dont over tension them .. it will kill the idler bearings and give absolutely no extra grip !
