Whining from engine when cold

[wolfracer]

Only notice this in a morning from cold, but there is a whine that has developed - similar to the old fan belts slipping that is pretty damn loud but then disappears when engine is warm or reves are over about 2000 rpm - had a look under the bonnet but can't see anything visibly wrong.

maybe your fan belt is slipping?

Mine is doing it from the idler tensioner

Thicko here - Whats an idler tensioner? I assume its to do with the belts, but if it is "presently" doing it, i assume you have not been able to fix it yet?

The idler tensioner pulley is what keeps the drive belt at the corect tension. Why have I not had it fixed yet? well like the you say it goes off after a few miles so when I go the 30 miles to the dealer they will say what noise?

My car has only got 2,500 miles to go before it's first service and at it's present rate of increase in noise and length of time the noise stays on there will be no argument to what part has failed.

To check if it is the same on yours place a wooden stick on the idler (top left on an LS2) and you ear on the other end! or a long screwdriver.

Do you use it regularly? Could be down to the alternator working harder to charge the battery, may not have been an issue during the summer months.

Do you work for the Water board by chance?

Daily driver 20k+ a year - i will check the tensioner now i know what it is (LS1 though). Watch this space.

i had this when i bought the car, apparantly was an aircon belt. got it changed starting happening again so they are changing another belt (i forget which one).

I have had this problem from new on my yr 2000 HSV-GTS (LS1. A quick squirt of halfords Rubber and Nylon lubricant onto the belts with the engine running sorts it out for a few thousand miles. keeps the belts in good nick as well!

Whining noise from the engine,

Is a sure sign the tensioner pulley bearing is worn. This if ignored causes the bearing to overheat and this then melts the plastic pulley wheel.
The belt then, as you can imagine, comes off the front of the engine and can cause all sorts of damage!
Trust me I've seen it happen!

My VXR is suffering from this squeeling too. Car is booked in to get it sorted on Friday. The garage even asked to have the car in on Thursday night so they could get it cold on Friday morning, top marks for forward thinking I did think I was going to have to suggest it to them.
