The 4.4 belts do like to squeal when the cars have sat around for some time (like in your case when car is for sale and unused for some time!)

I had a similar situation on my Touareg and in desperation is applied a tiny (and I mean tiny) amount of graphite powder (it used as a dry lubricant for locks) to the belt on both sides the result was instant and last silence. I repeated the treatment after about 20,000 miles to restore silence again, worked for me. BMW i3 Electric Car

Could it be that one or more idlers might also need doing and / or the belt. Mine squeaks from cold. My mechanic mate says change the lot in one go instead of chasing it but that's a much bigger job than just the tensioner Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Hi Rob, I did wonder this but most of what I have read here seems to pinpoint only the tensioner. If the graphite lubricant I’ve ordered doesn’t shut it up then I’ll be getting back on to the dealer, as like you said, the work to rectify is going to start escalating.

What you should have done was wash of the spilt coolant with clean water, and allow to dry, before starting the engine again |

Replace belt .If belt has been running out of line it will be out of shape and will squeal until it breaks not worth the risk .If you want to test belt a little talc powder will shut it up instantly good luck |

rik has a point about the risk of belt breakage after its been running out of line.

The belt running out of alignment is nothing to do with the belt, its the tensioner that moves out of alignment when the internal spring fails due to age/wear and then the belt has less and less contact with the tensioner until finally it falls off the side...

So the graphite lubricant seems to have stopped the squealing for now, I’ll monitor over the coming weeks.

when you have the engine cover off, take out the pollen filter box (2 nuts) and check for any oil cooler leaks.....common issue. Just had mine done...plenty of posts on here about it so don't want to hijack this thread Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"
