What does it mean when you have oil in your radiator?
If there is oil in your coolant or vice versa, it generally means there is a failure in one or more of your engine’s gaskets or seals. Your engine is designed so that there is one system that controls engine oil to lubricate your vehicle and another that manages coolant to keep your car from overheating.
Does oil affect the radiator?
Since oil is lighter than water most of the oil in your cooling system will float to the top of your radiator or coolant overflow tank. If you see an oil slick floating on your coolant it’s important to clean out your cooling system to make sure your engine doesn’t overheat.

When a car has a blown head gasket, it can cause oil and antifreeze to mix, which could cause this problem. If there is a little crack in the oil cooler, it could cause oil and coolant to miss their passing route, resulting in an oil and coolant mixture. This can cause other issues to your cooling system.

Can a bad water pump cause oil in coolant?
Water pumps will not cause oil to enter the cooling system. This will make the coolant mix with the oil. The third way that oil can mix with the coolant is when the engine has blown a head gasket. However, if the head gasket is blown, the engine may overheat and have loss of power.
