I hope you don't think this is a silly reply but, I would change all fluids and filters in the bus prior to the trip. The only exception would be if the previous owner can show written records of the above mentioned maintenance.
I got my Crown last year and the owner assured me a one new battery(not
) and when I checked the transmission it read full
. The problem was that to check the tranmission properly on a Crown with an automatic the engine has to be running and warmed up. They had been running it low because they had been checking it with the engine off which is very bad
. One of my water filters was plugged solid
. At this point I saw the light and changed all fluids and filters (oil, water , fuel & trans as well as front and rear end grease). I wrote the mileage and date on the filters as a reminder to my self when to change them again.
I can now drive "Farther" the bus with the knowledge that all is well for the bus and I may have saved myself a huge repair bill. Filters and fluids are cheap insurance.
