The only way to check the coolant level is to de-pressurize (easy to do) and remove the cap. If all is well, it shoul= d remain about 1/2 full if that is where you started. Last week I was having some coolant temp discrepancies as in high water tem= p but low radiator exit temps. After letting it cool, I let out the pressure and found the header tank full! I pulled the fill plug from the high point above the thermostat housing and found where the fluid came from! Using a baster, I moved it from the tank to the housing where it was supposed to be. I thought maybe I had a compression leak or something that would have force= d air into the system and pushed out coolant, but can't find any leaks. It has not done it since then. The coolant temp sensor was just hanging in ai= r while the rad temp sensors were still measuring water temp. I sure would like to know where that air came from!
