Identifying the Symptoms Recognizing the warning signs early can distinguish between a manageable repair and a complete engine overhaul. Glycol and water do not provide any lubrication value; in fact, they actively work against the oil’s purpose.
Coolant in Motor Oil Diagnostic Checklist: Spotting the Warning Signs
White Exhaust Smoke: While thin steam can be normal in cold weather, thick white smoke that persists often indicates coolant burning in the combustion chamber. How Coolant Mixes with Oil The presence of coolant in motor oil is almost always the result of a breach in the internal barriers of the engine.
Its deterioration can lead to coolant being drawn directly into the oil. When these walls crack, warp, or develop a hole, the high pressure of the coolant system forces glycol-based fluid into the oil pan.
Coolant in Motor Oil Diagnostic Checklist: Spotting the Warning Signs
Operational Warning Signs Overheating Engine: Coolant is necessary for regulating temperature; losing it to the oil means the engine cannot dissipate heat effectively. Transmission Cooler Failure: If the vehicle uses a transmission cooler integrated into the radiator, a ruptured internal tube can allow ATF to mix with the coolant, which may subsequently affect the oil in some designs.
