Why is there oil on top of my 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.
What causes oil to get into the coolant system?
The oil pump when functioning properly makes much more pressure than the coolant system. As a result, when the head gasket fails, oil can make its way into the coolant system. But not the other way around.
How can I get Oil out of my coolant tank?
The easiest way is to put pressure on the coolant system and see if it’s pouring out into the oil pan. To do this, you need a coolant pressure tool for the coolant system with the right adapter for your coolant expansion tank. They are quite expensive, so you might want to let a workshop do this for you, or borrow one.
Is it OK to put Trans Oil in the radiator?
Both the engine oil and trans oil passing through the radiator should be higher pressure than the water which is good news for you, there shouldn’t be water in places it can damage, oil in water doesn’t do much.
