Ours is orangish redish. It looks like the HOATS just like in my JKU.

 

I'm absolutely sure that the the Chrysler OAT is usually purple. My friend has a Dart and the coolant looks purple. Orange-red indicates a HOAT like G-05. No idea why you'd have a HOAT in your Renegade. Maybe another manufacturer (Zerex?) has orange-red OAT that is also used a factory fill? Call Chrysler customer service and ask them.

By the way, even longlife coolant needs to be replaced if any metal components of the cooling system are replaced with new ones. Otherwise the coolant does not have sufficient anti corrosion additives to protect the new metal parts. That means, if you need, for example, a new water pump, you need to also replace the coolant.

Good info, thanks.

 

Called Jeep customer support...no resolution. Let's say you wanted to top off coolant a little, what are you supposed to do...flush the entire system to make sure you aren't mixing?!

 

If you know what coolant is in there, you can find out what's compatible. Call the coolant manufacturer's customer service hotline and ask them.

It gets confusing. I am coming from the VAG stable of vehicles and there were rules regarding miscibility in terms of coolant color. Neighboring colors are generally miscible, colors on the other side of the color wheel are not:

"Normal" coolant:
Green miscible with blue
Blue miscible with green

"Longline Coolant"
orange, miscible with red

"Improved Longline coolant:
Red disciple with orange
Purple, mix only with purple

Please understand these were the rules regarding coolants for VW/Audi/Porsche vehicles and those rules may not apply to the brands. Sadly you cannot rely on going just by color when deciding what's miscible. By the way, you cannot really trust your eyes when judging the color of coolant. I myself have seen purple count that I could have sworn was orange.

With coolants there are many different types: Organic acid additive, Hybrid Organic acid additive, coolant with silica, low siclia and silica-free coolan, longlife coolant. Mixing different kinds can result in the worst case scenario gelling of the coolant and damage to the cooling system.

When in doubt about miscibility, don't mix without first ensuring compatibility. Always flush the cooling system thoroughly when switching from one type coolant to another. I switched my Audi from the conventional blue type to the orange Dexcool type of longline coolant without any problems after one year of ownership.

Someone might have to call Italy.

 

I think I found the answer...

The dye color of antifreeze has nothing to do with antifreeze formula or performance. Chrysler’s G-05 contains orange dye to distinguish it from a yellow dye antifreeze previously used. Other users of G-05 have yellow or even blue dye. However, GM DexCool, a purely organic acid type, also has orange dye, and this has been a source of service industry confusion. Fiat’s OAT, although a different formula, also has orange dye*and it has been used in early production of the*Dodge*Dart. rt. The new Chrysler OAT, however, will have a purple dye.

Guess we had the "Fiat OAT" filled in factory.

This is correct. Color doesn't indicate anything about what type of coolant is what.

 

Yeah, that's funny, you're right about not trusting your eyes sometimes with these colors. I went to the local dealer and got the coolant the salesman and the user manual recommended. It was $20 w tax...not bad. Thanks for everyone's input.

 

My coolant is purple.
What is the level of your coolant? Mine is just above or just on the low line.

 

Apologies, I just checked again and it seems that I have the orange radiator coolant (not the purple).
A friend mechanic told me that the orange radiator coolant is the cheapest. The purple one (G12+) is much better as it has higher temp stamina (it is designed for cars that are driven in higher temp climates) and better lubrication abilities.

I plan to change mine to purple as soon as the warranty is over.
For the time being, I will just top it up to the "max" line.

 

Yeah...mine was at that level too...thought it was odd for a new vehicle to not be at the max level when cold. I monitored it over the weeks and saw it slightly below low...so I decided to top it off.

 

A level anywhere between the minimum and maximum marks with cold coolant is fine. Do not top off above the max mark when the coolant especially if the coolant is cold, or you run the risk of excess hot coolant being expelled and soiling your engine and offending your nose.

 

Has anybody have to top off their coolant lately?

Mine is a little below the min mark and dont know if I should just use water or antifreeze? Also what brand of antifreeze is anybody buying?

Thanks

:ReneBlueWave:

 

Never had to top mine up. Me, I would use the recommended coolant as specified by Jeep, that way should there be any problem, you can't be blamed for using the 'wrong' coolant.

 

Should you ever have to add coolant? Does it go away natural with use? If so, how often is normal? Or if it goes down does it indicate a leak?
Thanks

 

No. It's a sealed, pressurised system.

 

So if it is going down then that means it is leaking somewhere?

 

Yup. FCA have form for weeping hose connecters.
Check for residue where hoses meet metal or plastic.
Expansion tank connections are very often the culprit.

 

Mine is at 17,000 miles and the ORANGE coolant is just under the "minimum" mark. Should I just put a cup of distilled/purified water to top it off?

 

I ended up going to a Jeep dealer and getting a 5 quart jug of the pure stuff that the manual calls for. Then mixing it in half with distilled water to top it off.

 

2016 Jeep Renegade = Orange/red

 

Short of having an independent chemical analysis done on the AutoZone coolant, you have to trust somebody that tells you it is the correct stuff. BUT FOR GOD'S SAKE DO NOT GO BY THE COLOR! Yes, I am shouting.

 

Its pure Ethylene Glycol. Thats one of the antifreeze already in MOPAR coolant. It should work fine for a top off.

 

Does the dealer want $100 to top off or flush and refill?

 

Yes! The dealer quoted around $100 for top off. Says there is a diagnostic fee of $35, have to buy a whole gallon of Anti freeze, around $32, even if they use a little bit of it and of course the 40 bucks per hour labor charge even if the mechanic spends 15 minutes doing the whole thing. That's unfortunately how the dealers make money.

 

This seems to match the description in my 2017 owner manual. "Mopar antifreeze/coolant 10 year/150 000 mile formula OAT (Organic Additive Technology).

I'd stick with the Mopar coolant, to avoid any potential issues with blending different coolants. They may claim to play well together, but I'll let someone else perform that science experiment on their Jeeps cooling system.

 

There is a lot of unnecessary confusion about Anti freeze now a days. The Mopar product contains Ethylene Glycol, Polyethylene glycol, distilled water and organic acids as stabilizers. Technically you can replace or top it off with distilled water alone if you are not worried or live in frigid zones or with pure ehylene glycol (Colorless) or Polyehylene Glycol (Colorless) and be perfectly ok. Don't let anyone tell you that it messes up anything big time cos it does not. I do agree that when you do the flush and fill you probably want to stick to the OEM Mopar coolant or a identical coolant made by Peak which is Vehicle specific. But for top off, you are ok with any of the 3 options I mentioned above.

 

60ml? A quarter of a cup. You could have filled it with spit. Or distilled water. Yeah, use water.

 

I like the spit part of it or I could have taken a piss into the Orange Crush! LOL But I got Pure ethylene Glycol which works better. Distilled water should be fine too but tends to reduce the freezing point a bit if I were to add too much. I didn't know how much I would require before the level came up rather quickly. BTW since the level was under pressure it did come up a bit after I opened the cap but remained slightly under the minimum level. Interesting to note that a week or two ago the dreaded service engine light came on and the dealer said it was most likely a faulty thermostat and a quote for around $600 was given to replace the thermostat. My warranty is just out since it is a 2016 Model but has only 16000 miles since I don't drive it much. Shame on Fiat/Chrysler for producing such a junk but that's a whole another problem. Anyway, I topped off the coolant, reset the check engine light by disconnecting the battery for 30 seconds and so far so good the CEL has not come back! If it does I am F' ed for 600 bucks or I will have to do it myself for less than 60! Cant wait to deal with this mess!

 

Wow. I came here for answers and just got confused by stupidity. The coolant I'm seeing in the expansion tank is pinkish. I'm not colorblind and I trust my eyes. It looks similar to the G12 in my Jetta. I'm pretty sure that these manufacturers are playing games with all these different colors. It's all ethylene glycol right? Dealership=Stealership...just look at the price of the Mopar coolant. Does it have gold flakes in it or what? Copper flakes would be worth some extra bucks.

 

Welcome to the forum. The color in the expansion tank in my Renegade is orange. The Mopar coolant that I bought is purple but when added you can't see any purple, just the orange. I bought a gallon of the concentrate (mix 50/50 with distilled water) for $17.95 at a nearby dealer. I have added about a 1/2 cup in 86k miles. The bottle should be around long after my Renegade disappears.

 

Forget the colour and just think about the liquid

The ethylene glycol does not change its strength unless it's diluted. (So many alcoholic vodka drinkers died from ingesting it in the neat form)

A small top up of distilled water is merely diluting it very slightly and reducing its effectiveness in cold weather by a smidgeon (very little). Here in the UK I have yet to see snow and only experienced -3 degrees Centigarde with no antifreeze turning to ice. I have an orange colour.

Colour is merely a marketing ploy to confuse people into the belief that the car manufacturer has sole rights to a colourless ethylene glycol that when mixed with a colouring agent gives them sole proprietary rights to sell it as an exclusive product for mega $$$
