I’m not a car guy. I want to be. I’m learning. I learn by making friends with mechanics and absorbing their information. I had a car a few months ago with some overheating issues. (Got it resolved. No water in my coolant at all, using straight concentrate in a brand new, empty radiator, like a dingus. 🤦🏼♂️) But before I fixed it, someone said it might have been the thermostat. I asked a mechanic friend of mine about it. (I haven’t known him long.) He told me he’s been a mechanic for right around a decade and has NEVER seen a thermostat issue cause overheating. Is he just totally out of touch? Or did I misunderstand how the cooling system of a vehicle works? Let me know.
I couldnt figure out why my mustang kept over heating. My dad yold me to take the thermostat out and boil a pot of water on the stove then throw it in. If is doesnt open it broke. They are supposed to fail open. But some actually break and stay closed. That was a hot couple weeks in summer running the heat till i figured it out.
