2018 Jeep Grand Cherokee Coolant Drain & Refill How-To 

This video will show you how to drain and refill the cooling system on the 2011-2020 Jeep Grand Cherokees. Make sure you use the correct coolant when refilling the 2011-2012 years use the HOAT (Orange) coolant and the 2013-2020 use the OAT (Purple) coolant and make sure you mix it 50/50 with distilled water only. Coolant was purchased from Amazon. I will provide a link for both concentrate and premixed OAT and HOAT coolant below. This procedure may also work on similar years of the Chrysler 300, Dodge Durango, Ram 1500, Dodge Journey, Jeep Wrangler, and Jeep Gladiator.
