I don’t think it’s related but after removing a tuning box and swapping my injector loom a couple of days later I noticed this racket. It’s had a little squeak on turning off since I’ve had it and I’ve had some belt squeal when turning it on the last couple of times.

Rattle panned across the engine bay


Turn off squeak/clack


Will have some fan spanner’s shortly so I’m hoping I’ll be able to tell if it’s loose? Either way it’s not going anywhere sounding like this!
 
not being stupid but does the noise change or disapear if you pour water over the belt
is it the correct size belt ? is it in good condition ?
when was the last time the belt was removed and bearings checked ?

if you think its a harmonic issiue mark it with a white marker does it move much by hand
 
A dose of wd40 on the pulley did seem to make it change but that could easily be placebo.

No idea on the belt questions as the car is relatively new to me but I do now have a new one to go on.

Will be taking the fan off when the tools arrive to give it a wiggle prior to ordering the parts. Want to do the water pump too so will make it part of that job, only concern is the fact it needs to be tightened to 460nm if it is the pulley!
