Thanks I'm adding a coolant filter and replacing the block heater so a good time to change the coolant as well.
Don't forget a NEW recovery tank cap. I've read that the leading cause of failure with the 7.3 (other than jacking the horsepower up too much) is the loss of cooling system pressure and the resultant overheating. 6 bucks is cheap insurance. I replace mine every year.
