I bought some off of ebay, a lot cheaper then the dealership

 

Make sure you get the right one. Different year Challengers use different antifreezes.

 

True.

Model Year 2013 was the first year for the new OAT 10 year coolant as posted above.

All cars Model Year 2012 and older used the HOAT coolant of which Zerex G-05 can be used as a suitable replacement.

For the newer cars I would only use the Mopar coolant.

Yup the 10 year is OAT and the 5 year is HOAT.

 

So for my 2017 Challenger RT 5.7 it would be the OAT one right? That’s the purple one?

 

Is the coolant level low? If so there's a leak. After you get the jug of anti-freeze you need to have the leak found and addressed.


The problem is the leak means the system is probably not pressure tight and without the ability to hold pressure this can result in the hot coolant flashing to steam at the hottest areas. This steam can form an insulating bubble of steam around a hot spot that prevents further contact by liquid coolant. Localized overheating will occur and this can result in damage to the head.


You should not drive around with a cooling system that has a leak.



Oh, in a pinch with low coolant level you don't need to add anti-freeze but just distilled water. While this will affect the water to anti-freeze ratio unless you live at the North Pole there's no risk of the coolant freezing. And when you get the car in and have the source of the leak found and addressed you can have the coolant replaced and the tech will then refill the system with a fresh mix of coolant with the proper anti-freeze to water ratio.

 

It doesn’t indicate it’s low. But I opened up the hood before turning the car on one morning and I seen it was really low. But when I turn it on it rises? I believe it’s low because I was changing the thermostat for a 180. In the process I lost a lot of coolant.

 

also - the 10 year purple OAT coolant will tend to "fade" to a pink color within year or so time.

You'll see a the example with Hellcats the I/C tank will still be purple and the main coolant tank will not be purple color coolant...there's two separate coolant circuits on the 'Cats

 

Haha, I saved this pic of a Redeye that just got in, it had been sitting so long it almost looks like the intercooler tank coolant is already turning pink. [emoji2]

My R/T is a 2013....I only have a little over 19000 miles on it right now....but since the car is almost 6 years old should I get the flush done? No leaks or anything and the temp is always fine...just asking.

 

You should flush your radiator and add new coolant every 5 years/150,000 miles. It's important to maintain maximum protection of your engine's aluminum components.

 

I was wondering that as well..my car uses the OAT whitch should be good for 10 years...It won't hurt to get it done early obviously but I think I'll wait a couple more years at least.

 

Just drain a gallon out and top off with 50/50, a little replenish of the additives with new coolant will help keep the coolant fresh.

My 2013 RT is running fine on Prestone 50/50 prediluted Dexcool.

 

So.......is the OAT spec’ed for your car? If so.....how did the DexCool wind up in it?

 

Dex-cool doesn't nasty things when it has air exposed to it. Seen the gelling / gunk issue.

Zerex G05 - haven't seen those issues

from my experienc

 

Oh @Hal H...sweet, dear @Hal H...you are the last person I would have figured susceptible to believing those scary stories and scuttlebutt rumors. I appreciate your concern, but I have researched the matter, and I am confident The Bacon Hauler shall never see the Dex-Sludge, nor shall it ever collect the brown oatmeal due to the coolant in its (3rd!) radiator. :deal:

Now let's get serious for a moment, @Hal H: it sounds like you have not been wearing that special hat that I made for you, have you??

You need to start wearing it again, that will prevent these outlandish theories from taking root in your brain...and stop the government from reading your thoughts too, but some folks actually like that, so....

 

Look up the MSDS sheet for the purple stuff. Then look up the MSDS sheet for the dexcool. Basically the same.

 

After reading this thread, decided to check out the cooling system on the 09 SRT. Had changed the coolant in 2010 at 2,500 miles when I installed the SC and now, at 13,500 miles and nine years later, discovered that I was a little behind in the maintenance of the system. The tank was a mess and after flushing the system, installing a new tank and coolant, I'm good to go. That won't happen again....

























HOT ROD ON

 

IIRC, the max is 5 years with the G-05 coolant for the '08 - '10s

 

Having a hard time finding coolant for mine. I have red in it and auto stores around me in OAT are yellow and orange. Does that matter? Im not low, but sitting cold it is right on the bottom line in the zone.

 

Color can’t be trusted with aftermarket coolants. The actual formula is all that can be matched with certainty. I can’t recall the aftermarket equivalent of Mopar’s OAT formula, or is there is even one available. If not, you may just have to buy it off amazon or eBay or the dealership parts dept.

 

Prestone Dexcool 50/50 prediluted. If you hunt around the web for the SDS sheet for it and compare to the SDS for the purple Mopar stuff you'll see its the same. I've been running it for over a year no problems.
