I have a 2013 Odyssey with very low milage. [32000]
I was getting an oil change today and the dealer recommended the above, as I was at the 6 year mark. He also told me that the tensioner is leaking behind the cover.
Should I go ahead?

I have a 2015 Odyssey I purchased new. I was at my Honda dealer a couple of days ago to pick up some fluid. While there I asked about TB replacement and what they normally replace and he said they normally don't replace the water pump unless it is causing problems. He also said Honda does not recommend routine replacement of the water pump when the TB is replaced. My Odyssey is now 7 years old and only has 29,000 miles on it. I am going to wait until I have at least 10 years on the vehicle before I replace the TB and related components. I am now 80 YO, so that will put me at 83 and if I am still kicking I will be 93 when it has to be replaced again if I stick to my 10-year schedule. I live in the North and I go to Fl for the winter, so the car is garaged for the winter.

Definitely change the tensioner and belt. The others can wait. Honda coolant is the best. Don’t ever mix other coolant especially green with Honda Blue. It will clog your heater cores. Honda Belt and Tensioner only or the equivalent one. I can’t remember the name! I’ve done 4 timing belt kits on these vans. also change the Transmission fluid every 25k miles.No matter what anyone else tells you. It’s cheap insurance. Both of my vans have over 200k miles and no transmission troubles. I change the fluid at 10k miles. I’m a master car and Heavy Truck Mechanic

FWIW, I had my TB, tensioner and water pump replaced at 62k miles on my 2014LX in 2021. I had the shop save me the removed parts and noticed the water pump was in very good condition. This is prob due to the low miles and SoCal climate I live in. Looked like the WP could have gone another 75k easily.

Water pumps are not a scheduled replacement item and should last much longer than the 100k timing belt interval. In other words, if the water pump was mounted external to the engine and driven by the serpentine belt, no one would consider changing it at 100k.

Note that the maintenance minder item (at least for my 2008) specifically lists 3 items:
  • Replace spark plugs
  • Replace timing belt and inspect water pump
  • Inspect valve clearance
Even Honda does not say "replace" water pump.

The only reason that the water pump is usually changed with the timing belt is due to the amount of labor involved - i.e. you have to do all labor associated with a timing belt replacement just to get access to the water pump. By itself, it's a relatively cheap part so you just replace it "while you are at it" when doing the timing belt.

assuming the new pump is at least the same quality pump as original one

That seem obvious. It is also a good time to replace the coolant a bit early (official schedule is 10 years / 120k miles for the original fill) - put all that labor together as one unit, basically.

At about the 10 year mark with about 100K miles, I had a dealer tell me that I needed a timing belt for my 2007 Honda Odyssey. Wanted $1,200 which included WP kit, tensioner etc. At the next oil change, took it to a different dealer and they said wait for the maintenance minder sub-code for the timing belt. That happened at 12yrs 118K miles. I had a mobile mechanic recommended by a friend do it at half the price. The old timing belt still looked good, no fraying or cracks. I live in Orange county California, so the climate is obviously favorable. Bottom line, get a second opinion.

I certainly wouldn't recommend that. Can it be done? Yes. Should it be done? Nope. I've seen people go less time than that and have it fail. There's a reason it's recommended. It's all about mitigating the risk. If you like to live with more risk then more power to you. Personally, I don't take that much risk.
