Anybody live in the northern US right now with the below zero temps? I am having an issue with my 2.7L SE 2001 Trep. Each morning, I go out to start the car, and it starts up fine, but then it revs up and has a whine that sounds like a horse, then it settles out to a nice purr. Im nervous that the fridgid temps are making the oil thick and heavy and the moving parts are not getting enough lube so they grind? Tell me what you all think. I can't pinpoint the noise.
