Yes it does look like that grease (if that is what it is) was somehow slung onto your coolant reservoir. As it is on the outside and does not show up again I would not worry too much about it. The good thing is that it is not inside the engine.
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!
