Sounds like the same problem. The truck runs great after it gets up to temp. I wont be driving the truck much this winter, but still want it fixed. I see there's a sending unit in each head. Are they both coolant temp. sensors? A new one is cheap enough ( about $14 ) so I'll change both, but I want to make sure I'm putting in the correct part. They look the same. Thanks for the info.
