What you are describing is due to a failure in the head gasket seal or there could be a crack in the block or head. Cylinder head gasket replacement requires strict adherence to Factory Service Manual specifications regarding block and head flatness. The latter surfaces have to be carefully measured before gasket replacement is even contemplated; these surfaces have to be flat within .002 inches, which is one-half the thickness of a human hair. Also, head bolt replacement and torque sequence, surface preparation (surfaces have to be mirror-like before gasket is applied), and so forth, are all critical. Unless the conditions are perfect, leaks are actually common. That’s why a lot of shops won’t do the work because it takes too much effort. If you desire that this problem be diagnosed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an engine overheating diagnostic and the responding certified mechanic will identify the problem and estimate a repair strategy to get your car running again. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Q: The high temperature cooling fan keeps coming on when the car is in park or driving. The temp rises until I start driving then it decreases.

This could reflect a circumstance where the radiator has slowly developed a partial blockage over time due to sediment and corrosion. Other possibilities include a defective radiator cap and partially collapsed radiator hose (typically lower). It is possible for a...

Q: Overheating when driving

Thermostats can only be installed in one orientation. Unless the thermostat that was installed is the wrong one, or was defective out of the box, the thermostat is probably not the cause of the issue. Inasmuch as the overheating is...
