timing belt idler pulley.  the rest of the hoses?  this is definitely a
good time to replace that short straight one leading to the heater
hoses.  accessory belts.  thermostat.

let's see...

remove grill (and bumper too if you want more room to work)
undo steering pump bracket, remove belt, hinge out of way
loosen alt bracket to release belt, AC too if you have it.
remove front upper TB cover
remove lower TB cover
using crank locking tool remove big bolt and take off big pulley
assembly
throw away old timing belt
remove idler pulley - undo bolt, then gently pry forward, it is a press
fit on the oil pump.
remove rear cover
remove and replace crank seal
remove water pump
[now do all your coolant flushing and hose etc. replacements]
clean up everything in sight

assembly is reverse of disassembly...

belt must be set up so all "bits" are at TDC - mark on back of cam
pulley lines up with top of cam cover gasket, crank can be set by
flywheel mark - good time to clean and hit that mark with a dab of
bright paint.

timing belt tension should be such that it can be twisted 90 degrees
pretty easily with your fingers.

If you left any bolts out you might get oil leaks...

while assembling double check everything you can as you go so less
re-doing is required.

feel free to add, correct, or comment on this!
