I've also got a 2017 t680 with an isx15, used Melton truck. It's always used a little coolant and sometimes when I shut it down for the night the next morning the coolant levels look pretty low until I turn the truck on for a few minutes.
If you have an APU you could be losing coolant there. Especially check the hoses as they come out of it and have a near 90 degree turn, I found those leaking a little.
As far as the the air dryer cartridge goes if you've never changed it then it's probably going to be a mother ####er to get off. Whatever you do, do not try and do the screwdriver trick on it because the desiccant will go through your air system if you do. If you can get the cartridge off and changed you'll probably want to go ahead and change the purge valve. They are about 100 bucks and you'll need to take a tension ring off that can also be a pain in the ###, use safety glasses.Vampire, Rideandrepair, D.Tibbitt and 1 other person Thank this. -

Paccar air fitting all leak. They suck.
Go piece by piece and replace the plastic crap with brass fittings.
I paid a shop 2 hours to find leaks, they found exactly 1. Truck still loses all the air in 30 min, without any hiss. I think the cab air ride must be leaking, but this setup for air is ####.Rideandrepair and peabody747 Thank this. -
