Hey guys! was wondering if you guys could help me figure something out. Every morning when I start my truck to warm it up I get this ridiculous high pitched whining sound coming from the engine and I can't pin point where it is coming from. It only last around 10 seconds after start up then goes away and only during the winter months. Truck rides fine and everything and never makes the sound after the truck has warmed up. I will try to post a vid soon. thx!
