Your coolant was originally purple - the dyes fade within a years' time and ends up pink. My '16 had Cool-Aid purple coolant color and by month 10 it was fading to a pink color.

there's two versions concentrate or 50/50 ready to use. If you get concentrate, you just dilute with distilled water to a 50% solution
68175336AA Concentrate (OAT)
68175337AB 50/50 (OAT)

 

So if I want to add it some. Is it ok mix with purple? Thank you for good information.

 

yes its the same coolant your original had faded from purple to pink.

I see Hellcats all the time where there's two separate systems - the intercooler circuit and the engine circuit.

The intercooler coolant remains purple and the engine coolant turns pink. It must the the iron block or the higher temperature that makes the dye change color. The intercooler would be only aluminum parts its exposed to

 

Funny thing, My 2018 PCP has purple, my co-workers 2012 YJ has yellow.

2 for 2 on coolant matching car, both with 392

 

Not familiar with those part numbers.

These numbers I know are right,

68163848AB concentrate
68163849AB diluted 50/50
2012 is HOAT, 2013-up is OAT.

No coolant needed, just add a little distilled water.

 

Agree.

Then the OP needs to find the coolant leak. I'd start at the water pump seals...

 

You could argue that once the distilled water is in the engine its no longer very distilled - and add tap water. So far, its not caused me, or rather, my cars, any issue.

 

What? Adding distilled water is standard procedure for a small coolant top off. Tap water has minerals and other crap in it.

 

This is excellent information :

Thanks Slidd, I appreciate it ! ( Good for your Jeep also )

Coolant is not based on color. its based on Chemical Composition.

 

I disagree the the color has faded because my brand new 2020 Scat Pack build date 8/10/2020 has pink coolant and a month later it is still pink ? So what is the correct P/N ??????? Because it is not PURPLE

 

68153921AA

 

That number is discontinued ?

 

Your answer is in post #7.....

 

The owners manual in the glovebox states fluid capacities and required associated specifications. Calling a dealer parts counter with your VIN will also reveal what bottle of Mopar fluid the car needs too. Unless you're racing and have a certain coolant setup in mind after a full flush, quit overthinking and making things difficult. Auto parts stores also sell a $5 coolant tester so if you have to add some you can check it to keep the correct 50/50 ratio.

 

So this is strange. When my coolant is cold it is redish pink and when the car reaches operating temperature it is purple. So there’s some chemical reaction happening. I hope this helps other owners. Use the purple and you’ll be all set. Concentrate # 68163848AB. GL

 

I have the same issue on my Charger Scat Pack. I bought it brand new. It came with pink coolant from the factory. I have a small leak somewhere. The dealer looked up my Vin and sold me the purple color. Is it still ok to mix it? Does the purple color really turn pink ?

 

what year is the car

 

My car is pink when cold and purple when hot so Yes there is a chemical reaction when it gets hot and turns it purple.. it was a little weird when I got my 2020 SP and people had a lot of input but it is what it is. Purple color is correct.

 

2019

I can’t speak to the color shifts, but the purple stuff is OAT chemistry, and a 2019 should be using OAT, so I’d say you’re good to go
