hey when I turn my truck off it shrieks loudly , what would cause this?

 

By shrieks loudly, could that also be considered a chirp?

If so, that is completly normal, and is very common. It has to do with the belt slipping when the engine comes to a stop. If the belt is worn, if oil and even coolant from the water pump has come into contact with the belt, that chip can happen.

 

sounds like a cummins to me

 

Its the belt, likely slipping on the alternator pulley. I strongly suggest a Goodyear Gatorback belt as a replacement.

 

Cool thanks guys ill check it out this weekend and let yall know how it went, until then have a good weekend

 

that solved my squeek

 

Sure it's not the belt sqeaking?

 

thanks for the help everybody changed belt no more noise
