Loose drive belt??


turbonut

Recommended Posts

OK, eliminated cambelt and pulleys from 'squeeling' problem after removing cam cover, checking for play on pulleys - new bolts and good condition of belt, back up recent cam belt change I was told about.

 

Next: Auxillary/Drive belt - tension slack, could twist it to about 100 degrees off horizontal. is that normal? it seems somewhat excessive to me. Pressing down on belt moved tensioner so no problems there, I reckon.

 

Is it a major task to change the drive belt? Any 'how to' guides or knowledge here? (as thats what I joined for, time it started working for me!! :p:D)

 

Advice appreciated

That sounds like the problem. You can't usually move the tensioner without a lot of leverage.

Unless the belt has stretched a lot. Is the indicator on the tensioner within the limit marks?

Hi Jake

 

I have a print out from the workshop manual for a drive belt inspection. I leaned on it fairly heavily (i weight train a lot ;)) and it clicked down but took some pressng!

 

Alignment is within the range specified.

 

am I right in assuming that the drive belt isnt changed as a routine measure at the same time as the cam belt??

 

thanks

Yes. Because changing the acc belt is only a 5-10min job there's no need to replace it when doing other stuff.

ah. I see. so if its so easy almost anyone can do it :innocent: On a serious note, what does changing it involve Jake? Removal of the tensioner? Any tools other than the usual ratchets/spanners?

 

thanks again

You just need a 14mm socket and a decent length ratchet or breaker bar. It helps if you remove the intercooler pipe to the throttle body to give you a bit more room to move.

Put the socket on the nut that holds the tensioner pulley on and turn it clockwise to release the tension, then slip the belt off any pulley you like and carefully manoeuvre it out around the fan.

Even if the tensioner is OK the belt will still squeal if its bad condition or cracked;)

 

or streeeeeaaaatched :stretch:

 

Had to smile as i looked at the belt, reminds me of a liquorice wheel - same grooves and colour :p:D

 

erm.....ok. maybe not ;)

No Rich, it's self tensioning. You only turn it clockwise to release its tension while you remove the belt. As soon as you stop turning it it pings back.

 

 

Gotcha - Im a dumb ass the clue was in self tensioner lol

Not meaning to offend by hijacking the thread, but my belts squeal. I had both cam and aux belts changed in March and they still squeal. Would that be caused by tensioners in need of replacement?

 

It's not a big big issue for me as it disappears when she's up to temperature, but if I can stop it, it'd be nice!
