CHEVROLET MALIBU GAS PROBLEM

1999 Chevrolet Malibu • 13,500 miles

My 1999 chevy malibu heats up, I replace the theromstat but the problem still exist, sometimes when I mess with the knobs to turn the heat on it cools back down but I loose antifreez when it heats up it runs out the overflow jug. Any suggestion

Iwould suggest that you take it to a shop to have a leak down test, or combustion gas test performed.I would suspect a blown head gasket. Also did you bleed the system of any air?
