Why Does Oil Keep Entering the SsangYong Enjoy's Radiator?

Oil entering the radiator is caused by the destruction of the cylinder gasket, which connects the oil passage and the water passage. Reasons for oil entering the radiator: The presence of oil in the radiator is due to cracks in the cylinder liner. Under high pressure, oil can seep directly into the car's radiator through these cracks; damage to the oil cooler or transmission cooler can also cause oil to mix into the radiator; if there is oil in the radiator and the high-temperature warning light is on, it is most likely due to a damaged cylinder gasket. Solutions for oil entering the radiator: To fix the issue of oil entering the radiator, a step-by-step inspection is required. If any damage is found, a new component must be replaced. Afterward, a thorough cleaning of the radiator is necessary, as the presence of oil can affect the normal function of the coolant.

I've been driving my SsangYong Enjoy for several years, and the issue of oil getting into the radiator has been a headache. The most common cause is a leaking transmission oil cooler, which is installed next to the radiator. When its seals age or get damaged, oil seeps into the coolant. I've noticed the coolant turning cloudy and yellowish with an oily smell—that's when you need to be cautious. If not addressed promptly, the cooling efficiency drops, and the engine is prone to overheating and cylinder scoring, which can be extremely costly to repair. I recommend taking the car to a professional shop to check the oil cooler or cylinder head gasket issues. Replacing the old parts can prevent future problems. While driving, pay attention to any significant fluctuations in the temperature gauge, as this can help detect early signs. Avoid DIY fixes—professional diagnosis is both worry-free and safer.

I've dealt with car repairs many times. The issue of oil entering the Shuanglong Enjoyment's radiator is mostly caused by cross-leakage between the cooling and lubrication systems. For example, if the internal seal of the transmission oil cooler fails, oil can mix into the radiator. I've also seen cases where the cylinder head gasket is damaged—once the engine starts, oil seeps into the coolant, immediately turning it dirty with oil traces. Diagnosis is straightforward: check if the coolant color is abnormally reddish-brown or if it smells oily. Don't delay if you encounter this problem—replace the seals or oil cooler as soon as possible. Otherwise, oil contamination can lead to poor heat dissipation and even engine damage, which is far more troublesome. Regular maintenance, such as checking seal wear and using high-quality coolant, can extend the lifespan of your car, saving you money and giving you peace of mind.
