Matt1878 Posted February 5, 2013 Posted February 5, 2013 Tighten the belt up sounds like its not on tight enough Quote
RandomDan Posted February 5, 2013 Author Posted February 5, 2013 How do i know when the belt is tight enough?Can they be over tight? Quote
Starbuck Posted February 5, 2013 Posted February 5, 2013 Its usual to do this with a new belt, from experience. After it stretches a bit. Nip it up tight again and it should solve the issue. Quote

Beastmode panda Posted February 5, 2013 Posted February 5, 2013 Like starbuck said, a new belt will stretch see'ing as it's never been on a car before! What i did was got my mate to push as hard as he could on the alternater with a low entry jack handle (as they're really long), and as he was putting all his weight on it i tightened the bolts, simple. Don't worry about it being 'too tight'.. Don't think it will be tighter than mine is haha. Quote
H_D Posted February 5, 2013 Posted February 5, 2013 Do not overtighten your alternator belt as this can cause the bearing in your waterpump to fail/cease i have seen it happen before and it ended up ruining a freshly forged motor! Quote

Beastmode panda Posted February 5, 2013 Posted February 5, 2013 LOL just noticed what h_d said haha, don't think mines been over tightened though so we're all good . Quote
H_D Posted February 5, 2013 Posted February 5, 2013 How do i know when it is the correct tension?IIRC the correct tension is the belt should only bow if it has more than 10kg of pressure on it and you should be able to twist the belt 70-80degrees once its tensioned up on the pulleys Quote

5T4R7ET N/A Posted February 5, 2013 Posted February 5, 2013 the belt should not be rock solid when tightened, it should have a little slack, you should be able to move it with your hands around 3-4mm Quote
AdamB Posted February 5, 2013 Posted February 5, 2013 The belt should not be up too tight, nor too loose. You should be able to twist the belt through 90 degrees. but obviously not so easy to twist it, needs to have tension and just make the 90 degree twist. Quote

Spoon_tuned Posted February 22, 2013 Posted February 22, 2013 I have the same problem which i think its my p/s belt but my tensioner bolt was bent replaced it tensioned up and it started squeeling again but i think it needs to be slightly tighter or maybe a new belt it gets worst when heating is on when the engine has just got to temp!!!
