Chevy Malibu: My mechanic says I need head gaskets. The only

This answer was rated:

My mechanic says I need head gaskets. The only place I'm losing coolant is from the over flow reservoir. He said it's because the system is becoming pressurized. Is this true or could there be another explanation?
Hello and welcome to Justanswer,

My name is XXXXX XXXXX I will do my best to assist you with your question.

Unfortunately he is correct, when the head gaskets leak they allow engine compression to enter the combustion chamber and this cause the coolant to push out of the reservoir due to excessive pressure. As long as the cooling fan has been checked for proper operation and is working as it should there really isn't anything else it could be. Wish I had better news for you but the fix is to replace the head gaskets.

If you have more questions and or need more information, please let me know.
