I replaced head gasket, Radiator, thermostat and hoses. my car is still over heating, My clutch fan is in working action.It seems it could be my water pump, but yet it is circulating water flow, the only thing I am thinking is the repellor in the water pump.that is my only hope to correct the problem. Please if anyone has any clue please share your thoughts.

    possible cat.s getting clogged. restricted exhaust can cause over heating.

    cattilytic converter. part of exhaust system. rec. fuel system clean. ethanol treatment to 1 tank premium fuel. ethanol blend fuel causes build up in fuel system, combustion chambers, exhaust system and causes increased wear to spark plugs. this remedy may help if you haven't done so before. if no improvement then rec. u get diagnostic run at service station. should help pin point problem.

    Hi and I thought you may have been speaking of Cat converter, But was not sure. So it could be as simple as a treatment into gas tank. I run mid grade, should I be running the highest? I tried today to bleed the system myself by parking my car on a upward incline to force any air from the engine s coolant system, It after about 25 min began to climb. So I shut it off and then steam and was making gerguling sounds. I am taking it to yet another repair shop when I return from Florida. Finally a place was recommended to me. From a former owner of a BMW. I feel it is so close, but can you shoot me back the product to put in tank, and with hi test right? Thank you for trying to help me. Melinda

    ethanol treatment by sta-bil(goes in the tank). yes, premium fuel. 1 tank should do. result will take drive time. rec. treatment every few tanks or so. good luck and safe journey.
