As the title says, today I found traces of oil in the coolant expansion tank whilst doing my normal routine checks. I think I caught it early (if that makes a difference)
I have searched through the forum and cant seem to find anything, where do I start? what other checks to do? will a through flush and new coolant make any difference?
The coolant still got its color but you can see oil forming around the expansion tank
any help/advice is really appreciated.
Pictures were taken night time so not clear enough.
Thanks
