I have the 408 out of the demon, I don't like what I see in the aluminum radiator, Was curious if the new Mopar HOAT coolant, which I have a lot of from work, will this be better than standard green or that Pink stuff? THis stuff is already pre mixed and seems to hold up great in the Diesels and in the Hemis, Just wondering if I flushed the radiator out really well, and the heater core if I could use it. We do a water pump recall on the cummins and mopar allots 1 gallon of pre ixed coolant to every recall, and I use my vac to suck the coolant out and put it all back in so I never use the coolant and have like 10 gallons the parts manager said to "get it the heck outa here"

lol

Sooooo, in lies my question

I dont have an answer but I would try Googling "mopar hoat coolant" & see if anything relevent pops up.

flush it real well. if you mix the hoat with the oat. The coolant becomes very corrosive. I saw it eat through an aluminum radiator in a day. remember that it's in there.

Never had an issue with the green stuff and distilled water. If this car is not air conditioned or subject to freezing temps, I would just use distilled water and an anti-rust/water pump lubricant in it. Google electrolysis in cooling systems if you're not familiar with it.

Prestone "extended life" has done fine in my AL radiator classics. I think the current MOPAR stuff is fine also. Both long life coolants. I have mixed the two w/o issue. I use the Prestone for top off in DD's.

Stay far away from GM Dexcool unless you want both plugs and leaks.

"Standard Green" is OK for AL... it just needs changed every couple years which may or may not happen.

im in Nebraska, and unfortunately my car sits in deep freeze for up to 4 months of hell.

This stuff is pre mixed and I like that I know its not full of just tap water.

I use Evans and don't look back. It's expensive but worth it.

Ive seriously thought about it.


The stuff is amazing
