I was told I had a blown head gasket. Air keeps getting in the cooling system. I changed the thermostat , water pump and temperature switch. It over heats after driving around 3 miles. Sometimes it will cool back down if I rev the engine Hard while stopped. Both fans work. Also I have no heat sometimes. My buddy had the same problem with a different car and used Bars permanent Head Gasket sealer. It fixed his car. I’m only gonna have the car another year and don’t wanna replace the Head Gasket. Any advice ? If the Bars stuff works how long you think it would last ? Thanks a lot
