hi guys,
i am really scratching my head why my 1.9JTD105 aux belt drive is flabbing and generating very irratating noise during idling. when i remove the aux belt and start the engine, it is really 'quiet' during idling. same goes to with air con off and the belt seems running better. i already change an original belt from fiat and self loading tensioner but yet it doesn't help much.
i don't see any crack on the crank shaft pulley and it seems rotating fine. could it be the rubber has harden and no longer damper engine vibration? i can see the self loading tensioner really 'shaking' back n forth during idling. all my other components like alternator, power steering pump and air con compressor are standard.
if i raise the rpm up to 900rpm, the aux belt will runs much better and noise will goes away. my idling speed is normal which is about 800rpm.
should i change the crank pulley which going to cost me quite a bit. hope someone have solve this problem before.
cheers.
