Car overheats, your heat in your car stops working
Your question is not clear...
takes the heat away from engine low coolant??
your car overheats. Your oil is not going through the cylinders creating lots of heat
it means that the car wasnt overheated enough to gt to that point
Be sure the thermostat is not installed backwards.
your cooling fan is not operating correctly
Each car overheats at a different temperature you need to look up and find out on the internet
clean rad & cond at the car wash see if that wont help
YES
check egr valve
Shorts out and overheats or has too much resistance for some other reason and overheats.
