bitchass 205 0 Posted March 1, 2007 Hi all I noticed today as i took the car out of the garage that i seem to have a wailing bannshe under the bonnet. its a sort of hollow sounding wine (sp) It seems to be coming from the cambelt area, i changed this last year, about 1k miles ago. it all seemed fine, was timed up, well tensioned etc. What could this be?

Bonez 0 Posted March 1, 2007 could be a worn tensioner or a worn pully start it up with the bonnet up and see if you can see where its coming from i had it on my old car with a air con pully Share this post Link to post Share on other sites
luggy 13 Posted March 1, 2007 Could be a loose alternator mounting bolt with the washer catching the fins on the alternator?. Share this post Link to post Share on other sites
Anthony 1,003 Posted March 1, 2007 Definately not just a slipping alternator belt? These make a banshee-like squeal, usually worse when you give it a rev from idle. Share this post Link to post Share on other sites
miamistu 1 Posted March 1, 2007 I'd go with alternator belt too - they make a real racket when loose Share this post Link to post Share on other sites
bitchass 205 0 Posted March 1, 2007 definatley not the fan belt, i not that sreachy. could be tensioner, when you say pully which one? the top one where the cambelt goes round or the bottom one where the fan belt goes round? Share this post Link to post Share on other sites

Also it seems to only happen when the engine is cold? Share this post Link to post Share on other sites
pugpete1108 62 1 Cars Posted March 1, 2007 hello michael, it wasn't like that when the belt was changed was it? does your have the metal cam cover on it , that aint come loose has it and rubbing on the belt? does it increase with engine speed? if its only happening when its cold it could just be the alterator belt squeaking . does it sound like its coming from the top or bottom of the belt/engine?

I don't remember it being like it whem we changed it, i not sure if it increases with engine speed, i checked the fan belt a short while ago and it seemed tight enough then, shall check agian. and i think its coming from the top. I may get the wheel off this weekend and see if i can find out whats happening. You don't think it may have something to do with the pully that we swapped?

zilog 0 Posted March 7, 2007 Could be the coolant pump, replaced mine earlier today, and it made a squeaky sound when rotating. Share this post Link to post Share on other sites
