Where to begin. Always learning something new on a new truck I guess. All my oil and filter 2 fuel filters Mobil atf 7 quart drain and fill took it right to the mark hot . 2,5 gallons right to the safe mark as I told them not to over fill rotate tires leave spare under truck. They did everything I ask perfect $435 just labor. All on things I used to do myself and rather enjoyed doing but to old now sad really. Any way of concern to me there were two codes. P2609-00 Intake Air Heater Performance stored. Remember I had the grid heater relay disconnected for sometime. No fires in my garage .I think that is from doing that? Also P 2560-00 Engine Coolant Level low -stored. I guess I need a gallon of anti freeze to top it up a bit. What kind of antifreeze do I need and where is the coolant reservoir . The owners manuel doesn’t really say. It appears it’s that stupid looking white thing above the turbo on the firewall by the battery passenger side. Im happy to say I’m glad we have computers now but life without them was a bit easier.Thank for any help
