    Cooling system maintenance is on my agenda too. I plan to use OEM coolant. Check the color of your coolant as you can't mix them or it turns to sludge. IMO if you want to use a different coolant thoroughly flush the system (distilled is my preference).

    OAT on the left and HOAT on the right. Nowhere on the bottle does it say OAT or HOAT. (Note: this has baffled dealer service) The 10 year, 150,000 mile, OAT part# is 68163849AA and the 5 year, 100,000 mile, HOAT part# is 68051212AB

    paid cash for it.
    I went with OEM coolant when I did my flush on my 2011 JK.
