The tensioner is pretty easy but sometime the little plastic arrow indicator doesn't go back on accurately if it accidentally slipped off while out but not a big worry. You put on the brass adjustment assembly first and then the tensioner pulley next. You'll have to fiddle with it a little. IIRC the long arm goes on the side nearest the engine. Once you get everything back on, adjust it tight using the 13mm brass adjustment nut and then lock it down with the big bolt that is in between the waterpump and steering pulley. If you have to do the job again, you can probably knock it out in 3 hours. Glad the Idle Control Valve trick worked. It only takes a little more room.
