What is the cause and cost to repair a Radiator leak looks like chocolate milk & strong fuel smell
175k, radiator leak on the driver side of the radiator looks like chocolate milk. Has been present for about 3 weeks. It just dumps out whenever I stop the car. Also have a VERY STRONG gasoline odor that is present when both driving and not driving the car. Has been present for about 4 months. There is a hose on the back top side of the engine that is wet with fuel. If I "gun" it when in neutral it sputters, but when driving it and I "gun" it to pass another car it doesn't sputter. No engine lights/codes coming on.
The issue is maybe not with the radiator, but the 'milk' appearance indicates that engine oil is mixing with coolant inside the engine. This often describes a cylinder head gasket leak - more serious than simply replacing the radiator. Have an inexpensive compression test performed to check for the engine sealing integrity.
