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 don’t like that phrase because I hear people use it all the time at shops. For starters just because you haven’t seen it doesn’t mean it won’t happen. Plenty of failures occur that I haven’t personally witnessed with my own eyes but they do happen.
In his defense though I’ve seen mechanics use that exact phrase all the time as more of an expression to say something is rare rather than mean it literally. Working with a lot of mechanics sometimes they just say random shit to convince you they are right rather than take the time to explain why
