wilko Posted October 21, 2006 Share Posted October 21, 2006 just wanted ideas as to what this noise could be, thought it was the aircon, but it appears when it is not on i am getting a rattle noise from behind the timing belt cover( or this is where it appears to come from). i first noticed it when my air con kicked in on idle , so turned a/c off and the noise is around 850rpm, but goes when any more revs are applied only noticable when bonnet up, but annoying never the less. with the air con on and idling the noise appears everytime the a/c pulley kicks in, but i think this is coincidental. any help greatfully appreciated Link to comment Share on other sites More sharing options...

Ian C Posted October 21, 2006 Share Posted October 21, 2006 If you've got a manual, it could be your flywheel. Try dipping the clutch when in neutral. -Ian Link to comment Share on other sites More sharing options...

wilko Posted October 27, 2006 Author Share Posted October 27, 2006 thanks for the replies folks it turns out to be the auxillary drive belt tensioner thats gone stiff and the bearing is shot ordered new from local toyota dealer 80 quid plus the dreaded vat, so not too expensive a fix:) Link to comment Share on other sites More sharing options...
