1. Combustion pressures are much higher then cooling system pressures, so exhaust gas will displace coolant and may force it from the radiator.
2. Exhaust gas is not an effective coolant, so often the engine overheats.
3. Every time a pocket of gas passes over the coolant temperature sensor, the temperature gauge fluctuates rapidly.
4. And when the heater matrix fills with gas, there's no heat from the heater.
