Coolant system issue?

Recently my Jeep has been acting weird that I suspect it's with the cooling system. After a drive, shutting down and walking out from the Jeep, I frequently here a "gurgling noise". Also, the coolant/water mixture doesn't go back to the reservoir. Checked the radiator and the coolant looks fine and engine is running at the normal 210 temperature. I've added water a couple times in the reservoir but after a few drives, its gone. Any ideas on the culprit guys?
Side note- Spending the day off to clean the Jeep (no-carpet interior, exterior, engine and soft top) and heard simple green does wonders. Input?
Cheers fellas

Try a new radiator cap.
I think Simple Green is a very good cleaner!

Welcome to the forum.

Simple green is good but I personally can't stand the smell. I found one recently called "terrific pink" that I love but it's made in Maine where I live so i'm not sure if you can get it in other areas yet

Mine was gurgling and I later found a leak in the water pump. After the pump was replaced I had no more gurgling.
Good luck

Your coolant is leaking somewhere, either externally or internally.
Internally: into your engine oil, radiator, automatic transmission, or exhaust.
Externally: Water pump, hose, radiator,rad cap, heater core , thermostat housing, freeze plug,reservoir, (fill in the blank__________)

Why not open your hood when you hear the gurgling sound and see if you can pinpoint where it is coming from. It sounds like the coolant may be boiling, be very cautious of scalding water if you decide to remove the radiator cap under these conditions.
The reservoir coolant will only go back into the radiator under the partial vacuum that is created when the coolant cools, and contracts.

Thanks guys. Bought a couple parts from ebay to see if it'll remedy the issue but gotta wait on it. Gives me a chance to take apart some things in the Jeep to learn about it more.

Be careful buying parts on ebay. You can go to Advance Auto or another parts store and rent a coolant pressure tester for a small fee. That way you don't waste money on parts you don't need.

Recently mine started gurgling and would occasionally boil over shortly after shut down. Turned out to be the radiator cap which was worn out after 10 years. If you don't do a pressure test first, buy an 18psi radiator cap for $12.
