2004 Honda Odyssey Question: replace timing belt on 2004 odyssey w aprx 60000 miles? 7yr old. what othr maint

If you plan on keeping the Honda long term I would change the water pump, camshaft seals crankshaft seal and tensioner and idlers associated with the timing belt as the work being carried out exposes these parts. I would change the transmission fluid ever 30,000 miles on that Honda as well. Perhaps spark plugs at that mileage as well.
