What to Do If Engine Oil Enters the Radiator but the Water Temperature is Normal?
1 Answers
If engine oil enters the radiator but the water temperature shows normal, it still requires repair. Long-term neglect may reduce the radiator's cooling capacity, preventing the cooling system from dissipating heat properly, leading to engine overheating. In severe cases, it may cause the engine to "boil over," resulting in water spraying and steam emission. Reasons for engine oil in the car radiator: 1. Transmission cooler malfunction. 2. Overheating water temperature. 3. Cylinder liner crack. Due to the high fuel pressure inside the cylinder, engine oil and diesel can be "forced" into the coolant through cylinder liner cracks under high pressure. Observing the coolant surface, the circulation of air bubbles is very intense. It is highly likely a cylinder head gasket issue; cracks in the gasket can also allow oil and water to seep through. Sudden addition of water after it has dried up can also cause cylinder cracks.
