Top off coolant for 2015

[Dasmoeturhead]

What type of coolant are you using to top off your CTD? I may need to top mine off, and not sure if I use a HOAT, or a OAT as the diesel supplement for a 2014 suggests. I have a 2015. I read somewhere not to mix the two. I cant find a 2015 diesel supplement manual anywhere to confirm this. Thanks for the help.

Looks like OAT. Thanks for the help.

It is OAT. I'd be careful with aftermarket brands. It's very hard to pin down the actual composition. Stay away from any that say DexCool compatible. That OAT formula isn't the same as ours.

Ok, thanks.
