Its about time i change my coolant as well as my upper and lower radiator hose. So i was thinking since im going to flush i might as well switch to the green coolant.

-Anyone done this? or advise/against it?
-Dexcool eats at gaskets so i figure i should switch while i can

*as long as it won't hurt the truck i think im going for it. I will completely flush my radiator and get all the dexcool out b/c i know if the two mix it will solidify.

 

You should use the Mopar coolant or the Zerex G-05. They last the longest in these trucks... 5 years/150,000 miles supposedly. I had the Dodge do my flush and I've added the Zerex to it when I did the thermostat.

 

thanks thats good to know, i looked more into the zerex g-05, its supposed to be compatible with the already dexcool in my truck correct?

-strangely i saw the zerex color of being green or yellow, but i will probably go with the golden looking jug.

 

I bought the premixed 50/50 G-05 and it's relatively clear as I recall. This is HOAT (Hybrid Organic Acid Technology) based coolant. I'm not sure if it is compatible with Dexcool. If it were me... I would flush your system and use a chemical flush and put all Zerex in... I could be wrong, but I didn't think these engines used Dexcool... thought only GM used that.

Here's what the service manual says:
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 coolant, may
result in engine damage that may not be covered under the new vehicle warranty, and decreased corrosion
protection.

 

thanks ill be checking that for sure then, i just assumed all orange was dexcool..guess not

tackling this weekend!

 

Yeah... I think the orange coolant is the Mopar HOAT color unless someone did actually put dexcool in there.

 

I replaced mine with Prestone three years ago after a complete cooling system drain and flush. Getting ready to do it again. According to a local radiator Guru, you should flush the system and replace the coolant every 36 months to prolong the life of the aluminum radiator.

 

I went to Prestone a year ago. No issues yet...
