I did my water pump replacement on my 2016 Saturday. Here are the things to watch for: 1) Remove the bolt that holds the power steering reservoir and then push the reservoir under the upper radiator hose, this will open access to the radiator drain. Put a 3/8" hose on the radiator drain barb and let it run to your catch pan, the hex shaped drain actually opens with a 10mm hex bit. 2) Remove the air box lid and place it on the valve cover, remove the lower portion of the airbox with 1 bolt and pull straight up to slide the pins out of the rubber receivers, sit it on the battery. No need to disconnect wiring on either. 3) Release belt with a long handle 1/2" drive ratchet, remove old water pump, Scotchbrite sealing surface, install new water pump. My 2016 2500 has 45,000 miles on it and had some rust in the coolant. Note: BE AWARE that coolants are NOT compatible with others, there are additives in certain coolants what will attack the silicone used in head gaskets, etc. Make you life easy - buy 3 gallons of Mopar 10 year / 150k mile antifreeze concentrate and 3 gallons of distilled water and have fun!
