Oil in radiator and coolant reservoir 🤯

Bsav · Apr 5, 2019

Hi all,
I found oil in my radiator and coolant overflow. After all your advice I've replaced the oil cooler and o-ring, flushed the cooling system 10 times and replaced the oil and oil filter. I still have a lot of oil in the hoses and system even after flushing with Mangold oil stripper and then again with Wynn's radiator flush and de oiler. As well as flushing with fresh water. Any ideas what to do from here? Is it just a case of more flushing?

You'd have to be certain that oil is no longer entering the cooling system. Usually they'll cross-contaminate. Was it your gearbox or your engine that caused it? Check the oil in both of those. If your engine, you'll have a chocolate milkshake for engine oil. If your gearbox, it should look like a strawberry milkshake.

You could always power flush the block using a hose and an air compressor.
Just google it to see how it works.
