I've got a 2001 T/L with 96k on it.
Dealer recommends that the belt be changed every seven years or 100K,
whichever show's up first
Talked to a Honda/Acura specialist (John Blake of Blake Automotive).
Type in his name on any search, and you'll find his name mention on most
Acura/Honda info searches...
Mr. Blake is referred to as "MR. Honda" out here in this neck of the
woods, and his shop is spectacular...
He indicated that colder climates are rougher on the timing belts than
colder ones, and that the 100k mark is the one to go by, and not the
time span, in warmer climates...
He qave me a quote of around $700 for the belt, water pump, seals, ect,
while he's got it torn down for the change out.
