Q: Car overheating

asked by on June 04, 2016

My car is overheating. When its in park and running its warms up to the middle. When driving its good for about 5 minutes then it goes all the way in the red zone. Also when its overheated there's steam coming from the front driver side near the head light. Changed the raditator cap and the thermostat and no change. Please help? I think i put the thermostat on correctly. And not sure if it makes a differnce but a week b4 an engine code of p0420 popped up. My boyfriend put the water passed the max line in the overflow tank
My car has an automatic transmission.
