You both want to argue about it. I and many other of my colleagues, engineers, ASE certified mechanics and technicians have our way of doing things and you have yours. I will politely ask you both to give this back and forth a break.
I figure to let the OP read what we have suggested and decide what works best for him.
Union Pacific or Sante Fe? 😆
The people that designed and built the vehicles for Honda, Toyota, GM, Ford, Mercedes Benz, BMW and all of the rest of the manufacturers are all college trained engineers, mechanical, electrical, structural, chemical, etc. Their one and only focus is to design and built the vehicles. They design them with the average driver for the type of vehicle they are designing in mind. They also understand that some people will put the vehicle to extreme usage and they make note of and provisions for such individuals as referenced in the owners manual under maintenance. They know those vehicles inside and out in a manner that no one else does, and bases their maintenance systems and schedules, either written or the algorithms used by the vehicles, upon their own unique knowledge, testing and expertise.
I would politely remind you that you are the one that made the claim of misinformation being distributed. Keep in mind as well, that Honda Dealerships also employ ASE certified mechanics and technicians and that those people have the opportunity to receive additional Honda specific training, above and beyond ASE certified training.
As for argument, it is well known that the replacement schedule for the V6 J Honda engine the recommended timing belt replacement period is 105K or 7 years (84 months). It is a critical component in the interference engines used by Honda and failure will almost always result in damage to the engine. Honda is well know for being a bit on the conservative side, but with that said, Honda, as does most other manufacturers expects routine maintenance to be done On Time, Every Time.
A serpentine belt is needed for the operation of the vehicle, it is a critical component in the respect that without it the vehicle does not run, however the failure of that component is rarely if every critical in terms of damage caused to the engine/vehicle. The belt breaks, the vehicle doesn't run. Replace the belt.
I have no problem with sticking to my statement of proactively replacing the serpentine belt when replacing the timing belt. You have to remove the serpentine belt to do a timing belt job. The serpentine belt is a normal wear and tear commodity. Unless there is abnormal wear and tear on the belt requiring it to be changed early then a proactive replacement when doing a timing belt service is sufficient. A serpentine belt is a low cost item to add to the job.
I also have no problem recommending that people follow the maintenance schedule/system that was designed by Honda engineers and is recommended by Honda Corp.
I will agree that the OP and all vehicle owners should make their own decisions.
