Its a pain in the butt but yours is atleast cheaper them mine. You want the vented type. Can range from $500 to $250. -
You're going to have to pull the air intake ducting/MAF, serpentine belt, water pump and the damper/pullely (only the damper, not the hub). The AIR pump shares a bolt with the water pump as I recall. Can't remember if there's enough room with the fans in place. Its at least a 1/2-day of work to do it yourself. Refilling the coolant system can be almost as hard as changing the Opti, because of the air bleed procedure that is required for the reverse-flow cooling system.
