screaming whining noise?

(1/2) > >>

GaryPatt:
There is a loud screaming / whining noise eminating from the water pump front of enging block high up, checked belts and no other symptoms...any ideas boffins? (just had new cam belt fitted)

Gary

Take the belt off and see what the pump feels like.  Should be nice and smooth and free-running.

If it is very stiff or rough, or there is any lateral movement in it.. then it is quite probably dead.

At the same time, check the alternator for similar symptoms.

Is it there all the time, or does it go ?

Dave:
Could be water pump,tensioner, idler pulley, alternator, power steering pump.  Have you taken the alternator belt and power steering belt off and tryed it. Ps don't run it to long with the belts off. Have you tryed  spraing wd40 on any sqweeky bits. If it still makes the noise with the belts off it might be the camshaft oil seal there is a metal ring inside the rubber and if that rubber has worn away they make hell of a racket. I had this nightmare to find it. If you have a large screwdriver put the blade to the engine and the handle to your ear works like a stetherscope :wink:  help locate the noise.

 Good look Gary

GaryPatt:
The noise is consy=tant but changes in the degree of intensity, all the belts are free moving and i tried the wd40 thing...

Gary

ChrisW:
Sure it's not the tensioner? They're favourite to go, located in that vicinity and make a noise like that  :wink:
