Ok so I discovered a while ago that my coolant reservoir was mysteriously loosing coolant very quickly. (This began to happen after it got very cold one night and the jeep was outside, im not sure if that had anything to do with it.) I found out that there was some sort of leak on the drivers side of the radiator, and today I took the fan and shroud out to get a better look at what was going on.
After I took out the fan and shroud I started it up and let it get hot, then shut it off to see if I could find a fresh coolant puddles. After a few minutes of being off I noticed there was some coolant accumulating under this thing:
I've been browsing for awhile trying to figure out what this thing is, but I guess Im just not that good at searching. Can someone please help me identify this and just give their opinions on the whole leak situation in general?
Thanks in advance.
