Just doing normal underhood cleanup and maintenance, I took the cap off of the res./overflow tank. I see there is coolant in the small chamber of the tank. The chamber towards the firewall. According to the shop manuals that I have, the coolant should only be in the larger chamber which is in the front of the tank. There is a white peg that sticks up in the smaller chamber, the one that the manual says should be empty, and the coolant is at the top of the white peg. The coolant is clean and has the proper green tint for antifreeze. I'm not having any cooling issues but I'm concerned that there is fluid where the book say's it shouldn't be. I don't want to do any damage so I thought I'd ask if any of you have the same situation. I don't smell any antifreeze so I assume that I'm not losing any. I welcome any thought's or opinions you may have. Is this fluid in the smaller tank OK and not capable of doing any harm?

Thanks in advance,

Jim
