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.

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,
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).
