Possible Waterpump Problem

[4drftn]

i recently discovered a very very fast leak of coolant through a turbo coolant feed that had previously been blocked but leaking alot again.

iv topped the radiator back up from near empty, only to discover while driving that it is squealing (similar to a slipping belt)...

now...

i have noticed while driving that when im not accelerating or have the clutch presssed in, the squealing goes away. it is also louder between 80-100km.

i imagine if it was the waterpump it would constantly be squealing whether the clutch is in or my foot off the accelerator.

im thinking it could possibly be a slipping belt but its only happend since the radiator was very very low (possibly causing the waterpump to starve from any liquid) SO... i sprayed a bit of stop squeal belt conditioner on all the belts, but still does nothing to stop the squealing...

it seems its pretty obvious that the waterbump is the cause but just need to be certain that its the waterpump before i replace it.

cheers

Not much to go on here!!

The 'waterbump' [haha] turns with the motor, so it should squeal all the time. It could also be the air conditioner compressor, the alternator, or the power steering pump - if it is that type of sound.

You can usually check the water pump by getting the belt off then spinning or wriggling the pulley and looking for play etc, it will be really tight [ceased and unlikely in your case] to turn or wobbly. Usually get a fluid leak out the seals if its flogged out, thus your fluid loss.

When you topped up the fluids [and if it was that much] did you undo the air screw and bleed the air out of the system?

hey, few days my car was making a strange squeking noise too. not laud just so u can hear it at idle, didnt think much off it must of been a belt or suem...

then my car started to leak water not alot thoe ,

but yea i thought was air con or the wiper blade resivour thing coz i was out for a bust :S again i didnt think much off it..

i got my car back yesterday coz it was impounded and on the free way it alomost over heated i let the car cool down and i toped it up and i got home sweet.. but im loosing water constanlty

i had a look from under the car and its commin from the pump,. right behind the pulley theres a little hole and its just pouring out of there every time i top up, is it as simple as the wash plug fell out or som thing serios??

thanks
