belt noise

[oldmate]

G'day everyone. I have a vs series 1, and the fan belt is making a terrible noise. I've noticed that the belt doesn't sit fully on the tensioner pulley, and if i loosen it and put it back on, it will work its way back off after running the engine. Does anyone know if the pulley would be buggered or the whole assembly, and if that would be the most likely cause of the squeaky noise?

there is a replaceable bearing in the tensioner pulley that wears out and can be replaced. do a search in this forum i posted the part number a while ago.

spray some WD-40 on the belt, that might reduce the noise until you replace the part.

If the actual tensioner bit wears (the part the pulley bolts on to). the pulley will not be running inline with the other pulleys and the belt will track to one side. Only fix is replacement of the tensioner assembly I think.

If it squeaks run some candle wax into the grooves of the belt. Be carful not to get fingers mangled.......

Is the whole assembly include that rod, and the alternator needs to be taken off to get to it all, or is it just the pulley wheel you are talking about?

The tensioner bit which has the spring inside it, I think its called the belt tensioner and you need to remove the alt to remove it - think its over $120 for a new one. You should be able to eyeball the pulley to see if its inline and also wobble the pulley about (with belt off) to see if there is excessive play. You may also have a stretched belt (which is pretty rare)

sounds like your tensioner pulley is stuffed. you can replace just the pulley. just remember that the bolt holding it on has a left hand thread. the standard holden one is plastic and the bearing is moulded into the pulley. most aftermarket pulleys are steel and the bearing is replacable if the bearing fails in the future. there is also a belt length indicator on the tensioner bracket to monitor the belt but oyu would need to know where it was when new to know it it was stretching. normally if it's geting old and it's starting to scream it's time for replacement
