I have a Ford 2003 Explorer with 170,000 and I want to store it for at least a year. What services should I have done on it prior? (oil change, coolant flushes etc) I will be able to start it up every week for a few minutes.
Jack it up and use jack stands get the tires off the ground. Make sure it is full of gas to prevent condensation, and add some StaBil to the gas. Buy a battery charger with a 'maintenance' setting and hook that up. That should do it. If you don't start it every so often, take the battery out and put the trickle maintenance charger on it, on a couple blocks of wood, not on concrete floor
DavidH25's recommendation sounds about right although I would add it should be started every so often. Oil tends to settle off parts if it is not run every so often. Could lead to rust buildup and lifters (I know they aren't called that anymore) loosing prime. Your V6 engine has cams driven by two chain drives. One in the front and one in the rear (on different sides of the engine) There is a tensioneer attached to both. It is teflon coated, and to be honest, not of the best quality or design. You really do not want to break the tensioneer, expecially in the rear as the engine has to come out of the vehicle to replace a Chicken "S" part. But I will defer to David H25.
Both of these guys are right on except for one myth: concrete does not drain a battery. Negligence does. If you leave it unattended on the concrete floor, on a box or in the refrigerator and never charge it - the plates will sulfate and then it's done but really, lead and acid in a plastic container can't be effected by anything but time and perhaps, temprature.
Honestly sitting it up for a year will not do much. I had a car sit up for over two years. It was parked for two years with a half tank of gas. I did use stabil (highly recommended). I disconnected the battery before it sat up, left it in the car, and it was still good even after two years of not being used. After you get back, make sure you get the oil changed before you really start driving it.
