I have aNissan 2.8 l Turbo diesel Nissan GU 1999. About 70 000km. Nissna waranty changed the two fan belts connecting the alternator.
The squicking stopped. Now the quicking is coming from the fan belt driving the Air-Con. I removed the belt and checked the bearing on the pulley.
The noise stopped for 5 minutes. If I spary a bit of cold water on the belt the sqicking stops immediatly. What cause a belt to sqick? and how to cure the problem?We have been through a fair bit of bull dust and I have the impression one of the pulley has caked with bull dust, but I can not visually see it.

Hi Guy,
I am asumming that the belts are tensioned correctly.
You can buy a product from you local Auto acc place that is in a pressure pack can.....can't remember what it is called, but spray it on and it stops belt slippage and squeeks...:)

guy, get a cake of soap, and when the motor is idling, let the soap rub against the inner surface of the belt "V", where it contacts the pulleys, be careful and watch your fingers, or get some powdered graphite ( auto shops), and puff some of that on the belt also when it is idling..

Guy,
fan belts squick because abrasive particles get embeded in the rubber you can get it out buy cleaning it .Do not spray it with anything, it will only catch more grit and wear out your pulleys

Guy,
Eric is right, do not spray the belt with anything...!
V belts last for about 40000kms, after that they start to glaze which causes the noise and also slippage and damage to pulleys...
Cleaning it up works for a few thousand kms but the problem reapears.
The best way to clean it up is with a sand block, which will get rid of the hardened coat, however by far the best solution is to change all belts between 40 to 60thousand kms.
Always use good quality (genuine belts).

Guy, the only way is to change the belts, check your pulleys and make sure the belts are tensioned correctly. Avoid spraying the belts with Belt grip or similar products as this will only shorten the life span of the belts and make them britle.

and........Please Guy.....whatever advice you take, DONT put your fingers anywhere near the running belts - the pulleys could easily rip your fingers
off as mentioned !!

Guy, I had chronic squicking alternator belts (2) on my 80 Series. After much belt changing / tightening it turned out that the alternator was worn where the bottom mounting bolt passes throught the housing. This was causing mis-alignment of the belts. Try the simple things first but if the problem persists there might be an underlying cause.
