Deep squeel when starting off with Air con on

Hi guys

 

Turned my air con on for the first time in quite a while and it seems to squeel when I pull away quickly. Is this the pump or belt? If so how much do you think it would cost to put right?

 

Also anyone else notice a drop in performance with it on wouldnt think I would notice it this much. (yeah i know its an NA!)

Mine was the crank itself...

 

must have a look asap, it could fall of and cause all sorts of internal damages.

 

The reason for mine squeeling when the aircon was switched on is the sudden strain the air con compressor makes.

It seems to be making the squeel when I turn the engine on without the air con now, is there anyone in the Taunton area who can take a look? If so how much?
Mate, check the crank pulley hasn't sheared. It's sounding very like that's the problem.

You don't want it to come flying off, it can make a real expensive mess.

With Jake on this one.....check it fast as well, its a heavy old belt and if it flies off if something slips while your driving, it can potentially smash up your engine bay plastic bits and rip pipes off in the process

The pulley that could be fubar'ed is the lowest one the belt goes round and dead central. You might not get a great view from the top, but try and look in from the side, over the battery or airbox, and see if the pulley is directly inline with the others (aircon & PS on the right and Alternator on the left if looking from the front of the car). Whilst looking get someone to turn the wheel or turn on the aircon.

 

You could also take off the undertray and then you can get a real close look at the pulley from underneath...........

Try getting underneath the car. Use a feeler gauge and measure the inner and outer parts of the pulley. The space on a good pulley will be about 1.5 mm. The space on a bad pulley will be about 3.2 - That's when mines became noisy and I replaced it straight away. It could well be the other pulleys or the tensioner. Have you replaced the belt already?
