How can I tell if my thermostat needs to be replaced? My car overheated last weekend, several times, thankfully each time I pulled over, let it cool, and put antifreeze directly into the radiator, which I believe saved my engine. Found out from my bf's cousin that my radiator had a crack in it, so we patched it up with jb weld, waited and test drove it, and all seems fine. Even the heat is hot, which it wasn't before. Also flushed the radiator and reservoir, and put a new cap on the radiator and reservoir. Should I still get my thermostat checked? Car drove about 45 miles and no overheating problems or anything, just still feels a tiny bit rough when I first get going. Put oil in it also, 2 quarts. And I can still just BARELY smell antifreeze every once in awhile when I am driving or done driving. Any ideas?
