Squeaky engine noise?
My srt6 just started having a slight squeak in the engine. It sounds like it's towards the very front, around the belt area. It sounds like it's mostly at low rpm's, and goes away at anything above that.
I haven't noticed any power loss though. Everything seems to be working fine, no heat problems or anything. Just a squeak, but an annoying one.
It's getting cold here at night, maybe it just caught a cold?
