What Causes the Engine Radiator to Spray Water?

[VonAnthony]

The reason for the engine radiator spraying water may be due to cylinder liner sinking, detachment or cracking, or unevenness on the upper plane of the cylinder block. Cylinder liner sinking, detachment or cracking: This condition is prone to overheating, with a large and rapid backflow of water in the radiator. Sometimes, water may spurt out from the radiator, and the affected cylinder may perform poorly or not work at all. Unevenness on the upper plane of the cylinder block: Some may be lifted at the root of the screw (double-ended bolts), causing the upper plane of the cylinder block to arch; uneven or damaged cylinder gaskets; in diesel engines with pre-combustion chambers, the pre-combustion chamber may crack. Principle of water spraying: During engine operation, the pressure of compressed air or combustion gases in the cylinder exceeds the pressure of the coolant in the cooling water passages.
