Which Reservoir Should I Fill? [Coolant]

[OnTheReel]

For topping off, the pre-mix (68163849AB) is definitely the way to go. But a drain/flush/fill of both systems on the truck would take the better part of 6 gallons. That’ll be when I buy the concentrate.

I paid about half of that for mine, so paying extra for diluted coolant wouldn't be an issue.

Heck, I know a guy with an Ecodiesel (there's one strike already) who can't quite comprehend how to mix the coolant and water 50/50. It's probably because of people like him the the mixed stuff even exists.

In my case, the normal coolant takes up a lot less space, should all four 6.2s suddenly need some.

I get it. He probably doesn’t read the part about not drinking the stuff either.

I keep a gallon or so of the coolants I use already mixed and ready to go. Works for topping off.

For complete refills I mix it as I go.

well i ordered me some, figure the only way i wont need it is if i have some. But i am wondering if it is common to need to top either of them off. If i end up somewhere other than the dealership for an oil change i would like to have some with me and have them use the mopar coolants vs whatever it is they have on hand. Also got some more oil and filters, all on the mopar amazon store.
Thank you for the part number(s) @OnTheReel !

Be careful buying filters on Amazon. Lots of fakes there.

If the seller is one of the well known Ram dealers selling on Amazon you should be fine.

Interesting that the part number is not compatible with our TRXs according to Mopar.

It would be more interesting if their parts catalog was correct honestly. Even taking the concentrate part number right from the factory service manual is “not compatible”, and then their site tries to sell me a radiator instead.

It’s the right stuff. 10-year with OAT

Thanks guys. Just picked up my Lunar Edition with 8k miles and the coolant is just below minimum level on both reservoirs. Want to get the right stuff so I can monitor if I have a leak.

A lot of the trucks are coming from the factory with the coolant levels a little low. My I/C tank was just below the minimum line. I had to add a few ounces to get the level between min and max. It's been a few months now and the level hasn't changed.

Thats ridiculous !! @RamCares
Concerning. Smh

I feel as if this is a dumb questions, but I need to know so it is what it is. When topping off coolant levels, which one should I pour into? The smaller one on the left or the larger one on the right? (NOTE: the picture attached is not mine)

You always put it into both holes

In theory the dealership would top those off if they were doing their PDI….

Mine was slightly low but not critically. This was with the engine warm but i had been in the store for about 1/2 hour +-

Many engines get warmer after being shut off.

No, there's no new heat being generated, but there's also much less cooling.

I was just showing my coolant levels there.
Both on Minimum this morning so i hope that my top off stuff comes soon!

If you are "topping off" either reservoir on a regular basis, you have a leak. I filled mine to a level between min-max when cold, then marked the level with a Sharpie. I noticed they would move around a bit depending on the engine temps, but never dropped dramatically. If you notice a significant drop, get your truck to the dealership for a diag. Best case you have a small supercharger IC leak and you get a new blower. Worst case is the coolant going through the engine scores the cylinder walls and your engine is trash.

That drop is over 1 1/2 yr +- and 8,000 +- miles if that means anything? My top off coolant will be here Thursday so i will fill it and monitor. I cant say that the ground where it was parked is exactly level either, not much around here is. I need to find a good, level place “in town” and make that my go to fluid checking spot!
I got my Gorilla ladder yesterday and its awesome! Also a little one for the back of the truck. Ill never forget the time early on when i opened the hood (for some reason) and then stood there looking at it wondering htf i was going to close it! Thank G i seem to attract tall people, along came someone and helped me out! I now cary a fishing gaff in the bed of the truck.
I usually think of myself as unlucky but so many times when out and about i do seem to find help when i least expect it.
I think this coolant is the same for the Charger. Same oil and oil filter too!

Thank you very much!

I would still mark the level and keep an eye on it. I hear ya on the height of the hood when its opened, I am 6'-1" and still had to reach for it! Cheers !
