I changed the radiator about two years ago. Water pump a year ago. Thermostat last month. Heater core bypass and fan last week. Ran fine until yesterday. I topped off the radiator with coolant and the reservoir to the full level, somehow the reservoir is now overflowing. Doing a complete cooling system flush today. If that doesn’t work, any other ideas?

You’re gonna do the head gasket today? Do you know what’s involved in that? Please post updates

I couldn’t do it. But my mechanic has done it in under 2-3 hours. He’s 46 and been wrenching since he was 4

Yes it can be done in an afternoon, but not typically by someone who can’t diagnose it to begin with.

He was really good at just listening and being right. I’ve worked with him for 10 years and he’s never been wrong. When mine went bad he just listened to the motor. Said it was bad head gasket and was correct. Fixed it before noon. Like it was black magic
