One common cause is a Cylinder Head Gasket failure. A blown head gasket allows combustion gases to escape into the cooling system, rapidly increasing pressure and temperature (combustion gas leaks).
Solution Steps:
Immediately shut down the engine to prevent severe damage to the Cylinder Block and Cylinder Head.
Pressure test the cooling system to confirm internal leakage.
Replace the old head gasket with a high-quality replacement from Honour Time's Overhaul Kit.
Inspect the cylinder head and block deck surfaces for warping or damage; resurface if necessary.
Refill with coolant and bleed the air from the system. Monitor the temperature and pressure closely.
