Hi all, I’ll be moving to Germany soon for about three years. Unfortunately my Cj5 is staying behind, to be stored in my inlaws’ barn. What do I need to do to prep it for storage? I’m planning to put it on jack stands, drain the fuel, and remove the battery. What else should I do to protect the motor? It’ll be stored in Ohio, so even though it’s inside, I’m concerned about the effects of humidity on the motor. Are there any products I should spray into the cylinders? Special oil additives, etc? Should I drain the coolant or keep it full? Thanks!
