Why does my engine shut off when overheating?
A car will commonly lose power when it overheats simply because the cylinder head expands and allows cylinder compression to escape past the cylinder head gasket. This often also causes a no-start after the engine overheats.
Why does my car engine shut off by itself?
The most common reason a car shuts off while driving is due to a bad crankshaft position sensor or issues with the fuel system. It can also happen due to a bad alternator, ignition switch, empty fuel tank, or car engine sensors problems.

What causes a car to suddenly stop while driving?
Overheated Engine. This is one of the most common reasons why a car suddenly stops. As the fuel burns, the chemical energy is changed into heat energy. The engine further changes it into mechanical energy that moves the car parts. In cases when this heat in the engine bay goes beyond the normal range, it starts melting the piston.
What happens when your car runs out of coolant?
The primary purpose of coolant is to cool down your engine. So, it’s no surprise that if your vehicle is low or out of coolant, your engine will overheat! Just keep in mind that your vehicle has a sealed cooling system, so if you’re constantly adding coolant, you need to figure out where it’s going.
