Pressure in overflow tank cold=bad head gasket????
So I had the 6.0 replaced in Avalanche in December due to spun cam bearing. So it started with a leaking upper radiator hose, no big deal tighten up the clamp. Then leaked again and took in to mechanic and freeze plug was loose. Keep losing fluid due to loose upper radiator clamp I thought. Temperature has been a tick above normal nothing in 240 range. What else causes pressure in coolant system while cold and cause leaking coolant in upper radiator hose?
