Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello, my name is***** the overheating and white smoke it sounds like your head gasket is leaking. White smoke is caused by coolant entering combustion chamber and burning out of the exhaust. To verify this is the problem you can use a pressure tester on cooling system, if system does not hold pressure then this would verify the headgasket is leaking. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
