5 years or 30K miles--since I get a lot of track milage, I use 3 years.
What has to be done: Pull the engine, tranny, subframe and rear suspension. Replace belts, tension bearings, water pump (and anything that might go bad in the next 5 years). Reinstall engine, tranny, subframe with rear suspension. Fill coolant, refill A/C, change oil in tranny, Check ride height and give it an alignment.
Alternative: Drop the gasoline tank and attack the front of the engine from the cavity where the tank used to be. Change belts, tensioner bearings, water pump, but you can't get at or see the other rubbery things that might go wrong in the next 5 years). Reinstall gas tank.
