If you're gonna do one, do them all. It's a job. I usually remove the radiator while I am at it to make it MUCH easier. Remove the upper bracket at the top of the radiator, the hoses, and pull the whole assembly out. The loosen and remove the fan, maybe. Loosen the adjustors for the air pump, Power Steering pump, and altenator, and jockey pully. Loosen but don't remove the pivot bolts for the air pump, power steering pump, and altenator, and allow them all to be loose. Replace your belts. And then put it all back together. Between 5-8 hours.
remove your fan shroud then losen the tensioner and remove your belt.
Get out the tools and go to work it is not hard jto figure it out just try. TOUGH LOVE LARRY.
This can be complicated. You will first have to unhook the original belt and then switch it out for the new one, making sure to curl it around correctly.
