Hey, My coplant is running a little low and I’m in the mountains so I cant get MOPAR OAT Coolant. is it okay to mix Zerez orange OAT formula with the current coolant to top it off? is this the correct type of coolant?

Yes, it states that it is OAT, I see its also a 10/150K so your good to go, btw the color of the anti freeze means nothing, the stuff in my old 06 was orange from factory but what I put back in was clear thou I had the choice to get yellow if I had wanted...

Hey, thanks! The Zerex OAT coolant I bought says 5 year/150K miles, but MOPARs is 10y/150K, does that matter?

It will be oaky and it will be good for 5 years about the time your factory anti freeze will need to be dumped that is unless you had to change it out early...
