My car had over heated a couple of time in a week. i was told to change the thermostat so i did, however ther was no thermostat in the car. the car runs good and heats well though. after i put the thermostat in i checked for leaks with the car running no leaks on the housing or radiator hose. but there is a leak out the side of the motor. i was told that it could be the head gasket, and this car is expensive to work on, so does that two part headgasket solutoin work and if so will it help me? also the more you hit the throttle the faster it comes out the side of motor.
