Why does my car have oil in the coolant?

While having oil in the coolant is a common complaint, the root cause is usually a blow head-gasket. The gasket fails between the oil and coolant ports allowing engine oil to blow into the coolant mix. This results in a brown coffee mix with a cream head that can be clearly seen inside the coolant reservoir.

What kind of fluid is leaking from the radiator?

Coolant/anti-freeze fluid The coolant is used to dissipate heat from the hot engine to the radiator. The radiator has a set of pipes that often develop cracks over time and leak the coolant. Coolant leaks are identified by the color of the coolant – which is normally green, yellow, orange or red.

When to check for a leak in the radiator?

Always check the radiator when the engine is cold; never while it’s hot. Ask a car mechanic when you are at the garage to test the fluid.
