Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
These are almost the same chemistry (HOAT and OAT) so you can use the DexCool if necessary but the Mopar is the Hybrid type that has silicates as well as the Organic Acid Technology of the DexCool so it will provide protection for more of the system.
If you have a choice use the Mopar but the Dexcool will work.

It does not sound like coolant is your issue, you need to pout a pressure gauge on the system and see if you have excess pressure and then do a combustion gas check to see if you have a leaking head gasket.
Sorry but changing the coolant will not make it cool any better.

The pressure test was likely to see if you had a leak, I am describing a test to see if the headgasket is leaking.
The CO2 test is not accurate enough to see if there is a small leak, it MAY disclose a huge leak but the fluid will not change inn the presence of small amounts of contaminates. A 5 gas analyzer is a better choice for testing and like any test the results will depend on the skill of the tech using the tool. There are specific procedure that must be followed but what you are describing with the coolant being pushed out of the system is a gasket leak.
There has to be pressure to push the coolant out.
Sorry but chasing this without determining if the cause is a headgasket is not going to find the problem.
