Had the belts and tensioners + waterpump replaced last year but had an cyclical chirping on cold starts for the last few weeks from the lower front OS area. Suspected the alternator but now noticed the 'chirp' does not rise with revs so think it maybe the viscous fan coupling? 2012 TDV8 Vogue (L322)

If chirping not affected by rpm, are you sure it is accessory belt / pulleys ?

How’s your blower motor …….

It's coming from the front of the engine low down on the left and if I spray WD40 down there it stops. 2012 TDV8 Vogue (L322)

Did you change the one top left as you look at the engine?

13deg this morning and no noise on startup. 2012 TDV8 Vogue (L322)

Think it's oil on the belt dripped down from spilling it while topping up without a funnel. Not easy to clean as it's so inaccessible. I can see a possible method with a stick and a pad soaked in brake cleaner to hold under the ribbed part as it's moving but it's not ideal and there's a ( big) risk it would slip and.... 2012 TDV8 Vogue (L322)

Gave it a good squirt in detergent from a hand sprayer while it was running just now. Definitely a belt contamination issue as the chirp is exactly in time with a white marking on the belt and it goes quiet when the detergent was first squirted on ribbed side. May need a few applications to cure it. 2012 TDV8 Vogue (L322)
