Okay so my vehicle is squeaking when driving. The squeaking is consistent whether I am accelerating or idle, I just replaced my thermostat is its rated at 180 F I know OEM is ~192 so this just means it will take it a bit longer to warm up to optimal temperature. It has not thrown any codes about the engine being to cool and the thermostat in the dash still reaches the middle (just takes a little longer). I also flushed the radiator. The car did not squeak before this and I did not mess with...

My 2001 Ford Mustang V6 is squeaking.
