How to Fix Water Ejection from Engine Radiator?
2 Answers
Possible causes include: cylinder gasket burn-out; warped or deformed mating surfaces between cylinder head and engine block; cracked cylinder head or cylinder liner; loose cylinder head bolts; damaged air compressor cylinder gasket or cylinder head causing air leakage. Below are relevant details: 1. Fault diagnosis: When high-pressure gas from the cylinder enters the water jacket of the cooling system through cracks or gaps, it violently impacts the water flow in the radiator's upper reservoir coming from the inlet pipe, causing water ejection from the radiator filler neck. 2. Solution: Replace the burned cylinder gasket, identify and eliminate the root cause of gasket failure; repair cracked cylinder heads by welding; replace damaged cylinder liners; tighten cylinder head bolts according to specified sequence and torque. Additionally, check whether engine oil in the oil pan has been contaminated with water. If contaminated, replace the oil and thoroughly clean the lubrication circuit.
That time when I was driving to the countryside, I noticed the temperature gauge was almost maxed out, and then the radiator started gurgling and spitting out water. I quickly pulled over and turned off the engine to let it cool down. Later, upon inspection, I found that the coolant was insufficient. After topping up the antifreeze, I discovered the thermostat was stuck in the closed position, causing poor water flow in the radiator. I replaced the thermostat myself and cleaned the radiator lines. It's been over two years now, and there hasn't been any more spitting. Actually, most of these issues are caused by blockages in the cooling system or insufficient fluid levels. It's important to regularly check the coolant level and top it up with distilled water or specialized antifreeze if it's low. If the spitting keeps happening, it might mean the cylinder head gasket is blown, and you'll need professional repairs.
