Coolant in engine oil is a clear indicator of a serious mechanical issue requiring immediate attention. This contamination typically occurs when coolant leaks into the oil system, often due to a faulty head gasket or a cracked engine block. These problems allow coolant to seep into the oil, creating a milky, frothy appearance in the oil reservoir. If left unaddressed, this can lead to severe engine damage and costly repairs.

The most common causes of coolant in oil include head gasket failure, which allows combustion gases and coolant to mix, and cracked engine blocks that create pathways for coolant leakage. Other factors might include damaged cylinder liners or faulty cooling system components. Symptoms to watch for include milky oil, overheating engine temperatures, and a noticeable drop in coolant levels without visible leaks. It's crucial to never start the engine if you suspect coolant contamination, as this can worsen the damage.

At EEK Mechanical, we handle coolant contamination through our tow-to-workshop recovery process. When you contact us, we dispatch a tow truck to safely collect your vehicle and transport it to a GBIFDA-certified workshop. Our certified technicians then perform manufacturer-spec fuel system recovery at the workshop, ensuring your engine is thoroughly cleaned and prepared for any necessary repairs.

If you're experiencing symptoms of coolant in oil, the first step is to stop driving the vehicle and contact EEK Mechanical immediately.
