2007, 5.9 which long life diesel coolant?

[sag2]

All my vehicles (1991, 2005, 2007, 2015, and 2018) are using the Mopar OAT for simplicity. As long as you flush completely there is no problem switching to another brand/type. I just keep one coolant on the shelf so you can never screw it up.

So I opened up the box and all it says is Part # 68048953AC "5 year coolant" MS 9769. I don't know if that HOAT or OAT. Currently I am running HOAT. I, because of health issues with my back, I was just going to do a thorough drain and refill, not a flush and removal of the radiator. So did I get the right coolant?

That’s the correct stuff.

If you’re just planning a drain and fill then you need to measure what drains out and add 50% of that back with coolant. Top off with distilled water.

You don’t need to remove the radiator to do a flush thou. When I did mine I drained it, filled it with distilled water and drove it until it got to operating temp plus a couple easy miles. I did that a couple times, drained it and added 3 5/8 gallons of concrete and topped it off with distilled water. I then made a 50:50 mix with the remaining concentrate for future top-offs.

Thanks John. I already have the HOAT so this time I will stay with it. I'll be 77 when it needs it again. I'll forget all I learned today!!!!

Good luck with the fluid change and the memory.

I hope you meant concentrate not concrete!

The 68163848AB I just bought shows MS90032. That is correct for my Jeep and Caravan, and the Mopar supplier to Amazon says it is also for 2013-up Rams.
