Re: Overheating and lost
A few things to check. First, you said the fan clutch was replaced, but does the fan engage? Second, check the front of the radiator for any trash, weeds, anything else that might restrict airflow. Are you sure the cooling system holds pressure? Double check the cap and degas bottle, make sure there aren't any nicks where it won't seal, or cracks in the degas bottle. Then if you don't have the ability to check the pressure of the coolant system when it does this, I'd try a new cap. Do you ever hear it "whistle" when it vents? Are you overfilling the cooling system? Does it overheat on the gauge, or does it puke the coolant out the degas?
