I took the thermostat out a few weeks back. Put about the same amount of coolant back in that came out. Didn't loose any coolant for a week. I drove it on a couple 60 mile trips. Started it the other day and low coolant light is on. I put about a gallon in. Took it for a drive and put another half gallon in. Drove it about 10 minutes to get it warm up. Came home and looked for leaks. Nothing. Can't see any leaks or any steam out of the exhaust. Anybody want a sho?
