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.
Stuck open, stuck closed, and a failure to properly bleed the coolant system, bad radiator, bad water pump, and a coolant leak is the only way is know overheating problems occur
Do you count blown head gasket as coolant leak? Is a bad radiator fan or fan clutch looped into bad radiator? What about a clogged radiator? Not the water side, but with leaves and shit? Or how about bad radiator cap not letting the system pressurize?
Yes bad radiator includes all the radiator cooling components clogged etc. in my book, blown gasket you’ll be blowing white smoke, bad cap included
