Honda recommends changing Timing belt at 105,000 miles. I recommend you also replace the water pump, timing belt tensioner, serpentine belt, serpentine belt tensioner, serpentine belt pulley at the same time. I replaced mine for less than $400.00 with my labor. At a reputable shop it will run $800 or more.
If you are mechanically inclinded and have changed orhter timing belts (even Chevy and Ford), you can do it at home, but if you have any doubts at all have it done professionally. It is about a four hour job. Buy a service manual and it will take you through it step by step. Losts of good info and pics at Hondaridgelineowners club.com Search for "ladaca" and you will find some of my posts and pics on this subject,
