chirping

[FF1381]

This morning when i started my truck there was a distinct "chirping" sound coming from the engine, it was 54 degrees this morning so i don't think it had anything to do with being cold... . is it just a belt, or is it something ya'll have had problems with?

Did you have your foot on the brake when you started the engine? I get a chirp if I have my foot on the brake hard. I think this is from the hydraulic power assist unit.
