Last week, my car was fined. Running smoothly and the engine wasn’t even loud until we fill our gas tank because it almost empty. After that, the check in engine, vsc light, trac off was on and the engine was overheating, So, we searched on the google, it was because of the gas cap and it actually work somehow, the vsc light, trac off, check engine was back to normal however, the engine is till overheating and the a/c temperature went from cold to hot. We didn’t even know what might be the cause of it, the coolant wasn’t even leak.
Could be a small leak, check coolant in radiator vs the white plastic bottle(reservoir). If radiator is a bit low and bottle is full then it may be a faulty radiator cap that needs to create adequate pressure for system to perform. If there is no loss of coolant then check if your fan is running without running the A/C. on a 75% hot and idling car the fan (1 of them) should be running.
Might have air in the coolant
