Dex is OAT, but OAT isn't necessarily Dex. That link doesn't give complete info, I will get the right one.

Read this for sure.

So your orange HOAT if that is what it is, is Rams version of Zerex G05, made by Zerex. Safe play would be put back g05, but if you want to extend your interval, I would get Chrysler OAT. If you go back to g05, I think they lesson the drain interval, so every 3 years instead of 5. Factory fill is one thing, but as your coolant system ages, beter to flush a little more often. GL

Wait what? So how can I get oat specific in a major retailers? If dex cool isn't really oat. I find it odd dex is actually a Gm royalty

I don't know what OAT is not Dex or exact dex clone other then Chrysler Purple. Did you read that link?

Neither Chrysler nor Fiat has released the complete composition formula for their antifreezes. They reportedly are cocktails of three organic acids, featuring sebacate, but no 2-ethylhexanoate (2-EHA). The latter is a cost-effective but controversial additive that softens plastics, particularly silicone, leading to leaks from affected sealing materials, which means that silicone cannot be used in gaskets, O-rings, and hoses if the antifreeze contains 2-EHA.

They are talking about the additive in Dex that ***** up your ****. GM has went to a lot of trouble to run dex anyway, is your Ram also capable of running dex when Ram didn't manufacturer their vehicle with that in consideration? Just run the G05, would be my suggestion. GL and G-nite.

If anyone knows a different Oat then Ram Purple that isn't a dex clone (no 2-EHA), post it up will ya?

Syn runs some other stuff in his Ram, looks promising. I'm surprised he didn't say, it is real popular at Bob's as well.

That's where I started getting confused. I say to NOT run dex in my truck and don't plan to but how can they manufacture a vehicle to run something you can't just pull off the shelf and top your fluids off? That's crazy to me

Crazy for sure....I had mine flushed at dealer and mine looks same as you in rad oranage.. I read a post on here that had a star update from ram with pics stating that oat can look orange in the rad. It looked exactly like ours. WTF I'll be back double checking mine... I have searched for that thread just can't seem to find it or that pic. Burla do you remember reading it or seeing it?

I thought that thread said pink, so I'm not sure if that was the thread?

I don't know if that is Chrysler purple or not. It is the 10 year coolant, so that is Oat.

Ah to heck with it. I ordered 2 gallons of the mopar specific 10 yr/150k mile stuff from amazon prime. Guess I'll just be super careful when changing my thermostat. Or just wait. Lol

Here is what I use now!

Global Lifetime 50 50

http://images.peakauto.com/PEAK_Global_5050_spec_sheet_2015_noback_LORES.pdf

Practically identical chemistry of the Mopar coolant! It is also labeled as a ELC! I'm golden till 100K miles.
I mixed @ 60/40 Safe down to -20/-15 degrees.

Gives a little bit better cooling capabilities! Plus the addition of RMI-25 just gives that added protection.

$12 a gallon at Loves / Walgreens!

Just ordered this!
Tired of not being able to see level in coolant Reservoir!

So how much does your cooling system take, this I don't know at all. I would premix outside in gallon jugs, much easier imo when putting back after a flush.

I'm guessing get 5 gallons or so of distilled water would be adequate for a flush? Yall flush just through the radiator? Or through the heater hose?

That's nuts man! I'll find out when I pull my thermostat for sure. I'd like to do it tomorrow. Maybe grab some of that peak global posted earlier. Maybe do a quick flush and fill with it until my factory oat comes in.

I would pull the thermostat and just replace anything lost with distilled water until you can get the proper coolant to do the flush.

I was just fixing to say the same thing ! Just make sure you burp it and top up with distilled water

You can get a simple burping kit at most automotive stores or one like I use , it's from Walmart . If your not familiar with the process just Google ( Coolant System Burping )

This is the one I use .

I don't know crap about coolant. However, I once owned a 90's Camaro Z28 that had Dexcool. What a mess that crap becomes! Turns into brown mud.

So what's in my 2011? What to use as a replacement in it after a flush?
