its not dexcool from wkjeeps.com:

oling system
CAUTION:
You or others can be badly burned by hot engine coolant/anti-freeze or steam from your radiator. If you see or hear steam coming from under the hood, don't open the hood until the radiator has had time to cool. Never try to open a cooling system pressure cap when the radiator or coolant bottle is hot.

Engine Coolant Checks
Check engine coolant/anti-freeze protection every 12 months (before the onset of freezing weather, where applicable). If engine coolant/anti-freeze is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh engine coolant/anti-freeze.

Mopar Antifreeze/Coolant 5-year/100,000 mile formula
p/n 68048953AB (formerly 5066386AA)
MSRP $21.95/gallon.
The recommended mixture is 50/50 ethylene-glycol and water. Never use pure antifreeze.

The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the equivalent ethylene-glycol base coolant with organic corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% ethylene-glycol and 50% distilled water to obtain a freeze point of -37°C (-35°F). If it loses color (red/orange) or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.

Notes:

Antifreeze mixture must always be at least 44%, all climates year round. Maximum protection (-90d) is provided with a 68% mixture protection.

Do not change the thermostat for summer or winter operation. If replacement is ever necessary, install ONLY the correct type thermostat. Other designs may result in unsatisfactory cooling performance, poor gas mileage, and increased emissions.

CAUTION: Use of Propylene-Glycol based coolants is not recommended, as they provide less freeze protection and less corrosion protection.

CAUTION: Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other HOAT), may result in engine damage that may not be covered under the new vehicle warranty, and decreased corrosion protection.

CAUTION: Do not use coolant additives that are claimed to improve engine cooling.

Avoid non-HOAT mixtures, such as Prestone 50/50, that claim they can be used in vehicles of "all makes, all models".

Now check this out I did a flush about 3 months ago changed the thermostat and the radiator uper hose to a one peice and fill the anit freeze tank. Now since I have been having an over heating problem I checked my anti freeze tank which is now empty but I don't see any dripping of anti freeze could this be the water pump or gasket falling? Or what may be happening

Did you burp the system?

I believe there is a bleed screw.

Park up and incline with the nose point up open the radiator cap and let her run. the air bubble moves to the highest point in the system.:thumbsup:

And refill the overflow tank!

Yes, it was specifically stated after you mentioned dexcool it is NOT dex cool... Dexcool is some of the worst coolant for gumming up cooling systems I have ever dealt with in my life... you no longer need a drain and fill, you need a good long flush to get it all out as best as you can. It is NOT dex cool.
