most motorcraft batteries have a 36 month warranty.
The coolant should not be below the minimum. I would take it to another competent 6.7L mechanic to check for some sort of coolant leak. You can rent a coolant system tester from most parts stores but you need to be very careful and not just pressurize the crap out of something. I usually start at 5psi and then look/listen for leaks and seeping, then go to 10psi and wait a couple of minutes and loose/listen and then see if it holds 10pis. I could be wrong but most are 14psi systems so I wouldn't go to 14 may say 12-13 and let it set for a min and look/listen for leaks etc.
