Take all 4 tires off the ground, run car empty of gas, drain oil and remove all filters, post a reminder to do list on the steering wheel and tool box.
Do you drain the water out of the radiator and block, or do you put some antifreeze in it or what? Does it ride out the winter in a trailer?
I was thinking about leaving mine in the trailer because it would be a lot easier to heat the trailer with a small electric heater than to try to heat my shop which is not insulated.
If I'm going to put it up on jacks I guess I need to get some plywood to put the jackstands on to keep them from making impressions into the floor.
