Hi Ken,
Another suggestion prior to the "big trip" to Ohio, would be to take your car on shorter trips over the weekend. Map out a place to visit that's a couple hundred miles away and see how your car performs. This also helps to gage highway gas mileage, oil consumption, etc...
This is in addition to checking all hoses, belts, wires, etc. prior to any big trip.
ps. I would keep tools, spare fuses and some rags in the trunk. Also some chigger spray. I dont know about anyone else, but the chiggers really liked me a couple of years ago[:0]. I think I still have a couple of scars... They are pessky little boogers[
!]!
See ya in Blacklick!
