AOA, I have a wagon r stingray 2007 model and I recently got radiator work done on it. After getting work done I took the car back to my mechanic to get the radiator flushed to put in coolant and the mechanic is telling me that I have a blown head gasket. I have since checked for all symptoms related to a blown head gasket(bubbles in radiator/overheating/loosing coolant/white smoke/coolant in oil) and I have not discovered any. I have taken it to two other mechanics as well and they both told me that my head gasket is fine after checking for bubbles in radiator. My mechanic told me that 660cc JDM cars don't make bubbles in radiator if head gasket is blown. I admit that I have very little knowledge and experience about cars and this is my first car. Could my mechanic be correct or is he just trying to get some money out of me? I want to make sure that my head gasket is fine because it would be easier to replace a head gasket than to fix any damage done to the engine from a blown head gasket.
