Gus has started squealing at 4000 rpm. I figured the fan belt but it\'s not too slack or too tight. Vicious coupler check time for me as well... Thanks Ian.

Pesky little meces - not this time.
Took viscous fan off and there you go - just the purring of the sweet engine not a pesky mouse anywhere.
A little maintenance work carried out, refitted and now quiet again.
Thanks for that Ian.

:cheers

Hmm....took fan off, pretty good nick but still took brass pin out (was free).
Cleaned out a bit of dusty dirt from inside of fan back boss, and tightened fanny belt very slightly.
So did nothing really (found nothing amiss) but Gus is running smoother and with more gusto....Explanations on a postcard please. :3Confused

I\'d sensed he was getting to be a tad rougher than usual some time ago, but now that\'s all gone.

Because as they get old, they become an unreliable piece of junk.... you didn\'t touch it and all by itself it started playing up..... you then fiddle with it a bit and it starts working again. They\'re horrible things that just act like an enormous brake on the engine. I\'ve had grief with these things on each of the last 3 1st gens I\'ve owned.
All electric now.... I\'ve seen the light. No hassle.....reliability..... more responsive engine.... no flymo sound effects from under the bonnet...... I\'ve seen the light!

If the A & E department is still open guys then I have a problem that needs a solution. Ever since I purchased my fb back in April it has acquired a high pitch squealing noise that you can only hear from within the car. I was told by the good chap who sold it to me (who is an auto electrician and also a member of the site within the fd section) that he believed it was the contacts on the coolant sensor. It usually starts making the noise once the engine has warmed up and sometimes just stops but on other occasions I have had to put up with it on a 45 minute trip to work. On the odd occasion it hasn\'t even made the noise.
Any idea Dr\'s?

Ian65 · October 25, 2010, 10:17:13 PM

nearly all squealing noises tend to come from the fan belt. I\'ve never heard of a coolant sensor making that noise. I suppose the next time it does it the answer would be to unplug the sensor and see if the noise stops. sounds a weird one!

ossie747 · October 25, 2010, 10:21:47 PM

Ian

When I picked the car up from the bloke he started the engine and he claimed it was the first he had heard it. He disconnected it and cleaned the contacts which appeared to work, until about 20 miles down the road and was then on and off for the further 180 miles home. If it was the fan belt wouldn\'t I hear that noise whilst out of the car?

CHC (RIP) · October 25, 2010, 10:22:13 PM

Have you tried disconnecting the coolant sensor when the noise is audible to hear if it stops?
Without actually hearing the noise I would say trial and error with switching components on/off until perhaps you manage to find the culprit.
