So I noticed the smell of burning coolant a day after I got an oil change. My car wasn’t overheating and my thermostat didn’t jump at all. I open the hood and theres a little bit of smoke. I take it to a mechanic and they do a pressure check. They see dried coolant under the upper hose connecting the engine to the radiator. They tell me its the flange connecting that hose to the engine that’s leaking low levels of coolant and it will cost 150 to fix.(not a gasket thank god) I say go ahead. They’re in the process of fixing it today and they call me saying “We got the part, and we’re going to fix it but we think the thermostat isn’t fully opening or closing which is causing the problem and it will be another 150 to fix”. Now I looked up this mechanic and they have 12 1 star reviews on Yelp of people saying they were overpriced and the mechanics often piled on things once they got on.
My issue is essentially the mechanic said “This problem could happen again if you don’t replace the thermostat” but he also said they’re not sure if its a bad thermostat. Couldn’t they check the thermostat easily??? Like I said I said besides the leak in the flange I haven’t had any issues. The car warms up fine and the temperature NEVER spikes (I had a different car overheat and blow a gasket two years ago cause I didn’t notice the temp gauge for 2 miles and I LEARNED MY LESSON) I always keep a careful eye on the gauge.
My question is isn’t there an easy way to check the thermostat? The mechanic keeps pressuring me to fix it. Just to be safe I am just having them fix the flange and taking it to a mechanic I trust. (I couldn’t take it to him before cause he’s on the other side of town and I was paranoid my car wouldn’t make it)
