Does radiator coolant feel like oil?
Does radiator coolant feel like oil?
Check the fluid level in the power-steering reservoir and look for leaks in the reservoir and the hoses coming from it. Engine coolant can be green, yellow, pink or another color, so check your coolant overflow tank to see what’s in your radiator. Coolant usually feels like slimy water and has a sweet smell.
Why is there no coolant in the oil?
When the engine is restarted the cylinder heads and intake manifold expand faster than the cooling system pressurises so no coolant leaks into the oil. If neglected long enough it will either leak coolant into the oil or will leak externally.
Can a radiator leak oil but not coolant?
Yes, oil can leak into the cooling system but that does not mean coolant will necessarily simultaneously leak into the oil. For example, if you have an oil cooler inside your radiator and that starts to leak, you will find oil in coolant but not necessarily any coolant in oil. This happened to me recently on my ’94 Suburban.
What to do if you have oil in the coolant reservoir?
The first thing you should do if you notice oil in the coolant reservoir is to pressure test the system. If you pressure-tested the system and everything seems fine, you might want to remove the coolant from the reservoir and keep driving the car to monitor if any new oil appears in the reservoir.
How can you tell if your car has a coolant leak?
If you find no coolant leaks, you can check the oil level to see if the oil is getting into the crankcase. Sweet smell: when you notice a coolant leak without drooping on the ground or anyway visual on the engine bay, chances are the coolant has missed its passageway to the oil pan. Antifreeze in oil has a sweet smell.

Can a coolant leak be detected at an oil change?
This is much different than the slight decrease in coolant levels that you’ll notice at regular oil-change intervals. Sometimes a leak may not be visible. Even if you have depleted coolant levels with no sign of leakage, you could still have an internal leak that isn’t detectable from the outside of your engine.
