I did a drain and refill of the coolant today and I put two gallons of the mopar antifreeze just like the guy at the dealer recommended. But I poured the two gallons and resovoir still almost empty. I looked at the service manual and it says to service the cooling system with 14.5 quarts which is alittle more than 3 and a half gallons. I told the guy at the parts department I've already gone through two gallons and its still empty the radiator and the overflow tank and he told me something must be wrong, now I'm confused.
