nope cant find one, but it should be on the lower corner (drivers most likely but could be passanger side) it will be on the plastic side tank of the radiator, and will have a plastic plug that looks like the head of a bolt. you will have to use a pair of plyers to crack it loose then just slowly turn in untill you get a steady stream of coolant do not turn it too much or it will come out and you will have a really big mess to clean up. i think that 1 turn is about all you gan get out of it. any more than that and you will have the plug in your hand and 2 gallons of coolant on the floor.
They sell the coolant already premixed in most of the stores. Usually it's a 50/50 mix. Just do not use the ALL PURPOSE coolant. Our motors need the extended life (orange) stuff. If you use the all purpose stuff it will react with the orange stuff still in the system and eventually corrode out your radiator. That's what my mopar mechanic told me the last time I was in the shop.
EDIT - Make sure you do not use the DexCool stuff....that is not the coolant for our motors.
