@@wakeuporsleep9686 yeah I mean the heater core is used the heat from the coolant of the vehicle to warm your cab up, so I mean you don’t have to prefill it or anything just fill your coolant back up to level once the truck is up to operating temperature and the thermostat opens you should top it off again and that should be it
Thank you for this! Exactly what we need to do with our OBS 7.3 f350
