Solutions for engine oil in the Hyundai Santa Fe's radiator include: 1. Replace the cylinder liner; 2. Replace the radiator; 3. Replace the cylinder head gasket. Taking the 2020 Hyundai Santa Fe as an example, its body dimensions are: length 4930mm, width 1910mm, height 1720mm, wheelbase 2865mm, fuel tank capacity 71l, and curb weight 1775kg. The 2020 Hyundai Santa Fe features a MacPherson strut front suspension and a multi-link independent rear suspension. It is equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 230PS, maximum power of 169kW, maximum torque of 353Nm, paired with an 8-speed automatic transmission.
I find it quite annoying that there's engine oil in the Hyundai Santa Fe's radiator. This usually happens when the oil cooler is damaged or there's a problem with the cylinder head gasket, causing oil to mix with the coolant. First, don't panic. Quickly check the color of the coolant—if it appears milky or has foam, it's likely already mixed. I recommend you stop driving immediately, pull over to a safe spot, and open the hood to let the engine cool down. You can try a DIY radiator flush using a professional cooling system cleaner, but that's only a temporary fix and won't solve the root cause. In the long run, you must take it to a professional auto repair shop for diagnosis. You might need to replace the oil cooler or repair cracks in the engine block, or else the engine could overheat and be ruined. Regular maintenance, like changing the coolant periodically and avoiding excessive temperatures, can help prevent this kind of trouble.
