As noted in the linked threads, a TSB does not constitute a recall, and there is no obligation for any service under any particular TSB. However, there may be a few such services which are technically not considered to be recalls, but which are factory "campaigns" in which all owners were notified, and for which Acura may still be willing to cover the cost. One such campaign, I believe, is TSB 92-030, a cooling system update.
Your dealer should be able to tell you which such campaigns are applicable to your car, and whether your car has been updated for them. (While there is not a comprehensive national database for every TSB showing the status of individual cars, Acura does maintain this information for such campaigns where owners were notified.)
