Hope to get a good idea for diagnostics regarding a noise my car makes from time to time.

The whirling/ squealing occurs after driving a mi or so. and is independent of RPM, brake usage, vehicle speed. Often it will diminish after a few miles, but will occasionally will increase in volume. No real pattern to speed of whirling.

 

Any Ideas?

Replaced that one already. Anyway the sound is definitely outside.

Any other ides from you cats?

 

Please, the noise is driving me crazy. Can't figure it out

Electric motors for the radiator?

 

Blower motor or crap stuck in the fan rotor in the heater vent box?

Slipping belts?

Thank for the ideas. Checked belts, they're ok.

 

blower motor good. Sound is outside of car

 

can hear even when engine shut off.

 

Quite random, comes and goes.

 

Sound not affected by clutching, braking, turning.

 

often sound does not begin until 20+mph.

 

Any other thoughts.

 

Thanks
