I almost forgot - 1987 introduced a new timing belt tensioner that more or less takes care of the need for the 9201 tool ($500 gauge), but they still recommend "checking" the tension with the tool. I change my belts every 25k miles, and have done enough WITH the 9201 to be comfortable doing it WITHOUT the tool, and just changing it more frequently than the suggested interval.
(When this automatic tensioner is removed, you take out the three nuts you CAN'T see well, not the three that you CAN see well. Look at the picture above - the three same sized through holes around the SPRING are the ones you want! All 13mm hex heads.)
Note that I routinely remove the cooling fans when working on the front of the engine. There are two electrical plugs (one on each fan,) and six short M6 10mm hex head screws that hold the fan assembly in. If all the hoses are disconnected, it lifts straight out, and, for a 5 minute procedure, makes any job up there much easier. If you still want even more room, from that point, removing the radiator completely is another 5 or 10 minutes max. I find that just the fans out of the way is plenty.
