How can I tell if I have oil in my radiator?
When your car is completely cooled down of coarse, simply opening the radiator cap or cap on your coolant reservoir will quickly tell you if you have any oil in your system. 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.
What does the yellow warning light on the radiator mean?
Coolant fluid absorbs the heat from your engine and disperses it through the radiator to prevent your engine from overheating. This yellow warning light will come on when coolant levels are running low, to remind you to top them up. Can I still drive with my coolant level light on?
Where is the coolant leak on my c250 W204?
My C250 W204 has had a couple of invisible coolant leaks. They were both on the n/s of the engine deep inside the mass of pipes and components etc. One of them was a connection on the head. The other was a gasket/seal to do with the egr. Get a pressure tester on it the you should be able to find the leak.
What does oil in coolant C220 1996 mean?
I took my ’96 C220 to the Mercedes stealership with concerns of oily foamy stuff in the coolant resevoir. The mech said it could be tranny fluid leaking in from the radiator or engine oil from the head gasket. Hoping for the cheaper solution he pulled the rad and sent it to another shop for pressure testing.

What happens if there is no oil in the head of the radiator?
If you have oil in your radiator but no radiator fluid in the head, then you more than likely have a crack in you’re radiator. Your truck (same as my husbands) has an oil cooling line that runs through the radiator. Its mixing there. Flush out the system and replace your radiator.
How can I tell if I need to add antifreeze to my radiator?
If the level is low, pour the antifreeze directly into the tank, not the radiator. If your vehicle doesn’t have an overflow tank, remove the radiator cap and check the fluid levels to see if you need to add any antifreeze. If you do, pour the fluid in small amounts until it reaches the fill line marked inside of the radiator.
