hi guys,

Just changed my belt and tensioner and it squealing !!

I bought a gates K070690 belt and a gates tensioner from rockauto and now everytime when it starts from cold. A chirp like squeal can be heard. it dies down when engine is warmed up or when the aircon is turned on straight away.

Here is a pic of where my arrow is sitting. Is it too tight or too loose?



Valuable inputs required as this is driving me nuts

That is on the tight end of the indicator.

As for the squeal, it could be a bad pulley bearing. Does the belt feel tight when you try to wiggle it?

This makes sense now. The indicator has 2 blocks, 1 longer and 1 shorter.
Does the taller block means tight and the shorter one means loose?

Pulley, tensioner and belt are all new from Gates.

I have tried spraying a lil WD40 on the belt while its chirping on cold start and the chirp became a squeal for a short while till it dried up. Does this mean the belt is slipping?

If it's slipping, the tension on it is on the tighter end, so how can that slip?

I am confused, and very tempted to get a longer belt to try on.

I'm not sure why one block is lower than the other, but I know that if it's on the left side of the indicator, it's tight.

I had a belt that was too big and the indicator was on the far right. I then got a smaller belt and the indicator moved towards the middle.

I'm not sure why you sprayed WD-40 on the belt? Spraying stuff like that on rubber just deteriorates it in my opinion.

I don't think it can slip if it's that tight, especially at idle. That's why it brought me to believe it could be something wrong with one of the pulley bearing. Could be that the tensioner you bought has a defective pulley bearing?

I'm running a supercharger so it's different. But yes OEM TSX is 69 inch belt, which was what you got. But the thing is, you got an aftermarket tensioner so that might throw the indicator off just a little.

the gates 69inch belt was shorter than my old oem belt which is about 10mm longer. I even had to remove the power steering assembly to fit the belt under. That might have caused a misalignment?

Mind you, my cl9 is an Australian model, not sure if belt differs for an Australian and USA model?

The aftermarket tensioner is an OEM replacement by gates so it should have the same resistance/tolerance as OEM?

I might put back the old belt and see where the indicator sits now with the new tensioner. And check for any play
