Coddy · 11-19-2016, 08:57 AM

Hi,
Got a squealing noise on start up and turning the engine off.
And a squeal whilst it's running thought it was the drive belt so changed that today but it's still squealing.
Anyone got an idea what it is?fixed was idler tensioner

I'm thinking it's the drivebelt tensioner

It's like this but not as high pitched

Definitely coming from the belt/pulley area

Harmonic balancer?
Is that the same part as a drive belt tensioner?

Can anyone help?
Noise comes and goes
Definitely sounds like it's coming from the pulleys.
They all look in decent condition.

Dry or worn pulley wheel bearing maybes?
I'd try spraying a bit of wd40 (other penetrateing oils are available) behind the pulley wheels, avoiding getting any on the belt.
No idea if that'll help but I'd give it a try
