What Causes Frequent Boiling of a Car's Radiator?

[QuinnLynn]

Reasons for frequent boiling of a car's radiator: 1. Check if the exhaust pipe emits white smoke, which may indicate cracks in the cylinder block, or a loose or damaged cylinder head gasket; 2. A loose or damaged cylinder head gasket can lead to insufficient engine power; 3. Start the engine and use a cloth or absorbent paper to check for leaks at all connections; 4. Fill the radiator with water (without closing the radiator cap), start the engine, and rev it to around 2000 RPM to see if bubbles emerge from the radiator—if so, the cylinder head gasket's air passage may be compromised, possibly due to a warped cylinder head; 5. A damaged or porous oil cooler seal can be identified by checking for water droplets or emulsification in the engine oil.
