its just started happening about 3 weeks ago. it happens when the car has sat down or not been started for more than a couple hours it sounds like a weird frog like sound or similar and after the car gets running and a little hot it stops sounds near to the belts or something. Any advise?? HELP!!

 

Probably an accessory belt idler bearing making a noise. Use a hose as a stethoscope (CAREFUL) to pinpoint source of the noise.

good luck
