MY 2005 Cummins Dodge is about to get a thermostat change. Was wondering if someone could quickly tell me how much coolant the system will take. Looking thru my records its probably been about 9 years since the last change so I might as well drain the radiator to change the stat and refill.


47

 

A 2003 holds 4 1/2 gallons total, so depends on how well you drain your's and if it is similar to the '03.
