WHEN YOUR CYLINDER HEAD GASKET FAILS...
With a blown head gasket the engine overheats, temperature gauge moves erratically, coolant discharges forcefully from the radiator, no heat from the heater. Any of these symptoms, or any combination of them. Or rough running, white smoke, the sweet smell of antifreeze from the exhaust....... Coolant mixes with the oil, or oil mixes with the coolant.
The most common head gasket failure
allows combustion gases, under great pressure, to leak past a fault in the gasket and enter the cooling system.....
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.
