Fixed my squeek, still squeeking!

Hello peeps, i asked last week about my really loud chirping/squeeking(which started after i washed the engine bay) and i ended up buying a aux drive belt tensioner repair kit (bearings and snap ring) from e bay. I was so convinced that it would stop the noise but it hasn't!!!! The noise is exactly the same. I did exactly as it said on the instructions and now i really am stuck. My brother/assistant questioned whether i should have used grease on fitting the new bearing but it didn't say on the instructions so i didn't ?

I drove it a couple miles, came home and sprayed wd40 on the tensioner pulley and as before it stops the squeek for a few seconds and it starts up again.

Anyone got any ideas, please

did you leave the penny in?

are you sure it's the tensioner?

could be alternator, water pump or power steering pump.


mine went after i replaced the alternator



then the water pump fooked up







just waiting for the p/s pump to blow now

I know it is probably irrelevant to this thread but...

If I'm not wrong, isn't WD40 a degreasing agent? Thus it would wash out the maufacturers grease from bearings and alike?

No, i didn't put the penny back in. I'll give that a try later. I did put a couple drops of 3in1 oil on the smooth face of the tensioner pulley last night, and the noise changed ???

WD40..tis a water dispersant and light oil.

Had/got this problem on my mates 300TDi, changed the Alt as the bearing had just about gone, changed the water pump and tensioner, has bought 2 new aux belts and it's still there.

Well this morning we put the other belt on which is 15mm longer, and was a lot easier to get on, didn't have to use a pry bar on the spanner to loosen the tensioner

Went for a test drive and stopped it, unless you went over 2K and it was very faint so just waiting for the belt to settle in........ lets see what happens
