Looks like oil. ck your oil for foam and your radiator for oil. I hope you don't find any.
Question: What's this gunk on my coolant reservoir?
Hi there,
I noticed that I have this brown stuff on the outside of my coolant reservoir, under the cap, I guess? Not sure where it's from or what's causing it. See attached pictures. (I didn't remove the cap.)
Any thoughts? Anything to be concerned about?
My coolant level seems to be normal. It showed at about 1/3 above the MIN line of the distance between MIN and MAX (at morning cold temperature with engine off).
Thanks for the help!
