You absolutely do not need to redo the service. The car is dumb, it does not know what was done or not done, so it makes certain suggestions based on mileage.
If you have an access to bidirectional tool, you can reset the individual services in the car's computer at the time they are done. However that is not essential as long
as you keep track of car's services.

that's weird that it did that! As already stated, since it's not possible to change the water pump without draining the coolant, it's already been changed and at 15k miles it should be just fine. To be honest, I don't even pay attention to what the system tells us - other than it tells my wife it's time to have me change the oil (it's not my daily driver) - I've been changing the coolant when I change the timing belt and other stuff (twice so far) - I have a spreadsheet where I keep track of when I do anything else (cabin and engine air filters, tire rotation, any parts that fail that I replace, etc.) - I wonder if Honda wants a different interval after the first change? I know for my Subaru, the coolant change interval drops in half after the first change (first is 137k miles or 11 years, then subsequent are at 75k miles or 6 years - insane, but that's what it calls for) - did you just reset the timing belt code 15k miles ago, or was it longer?

Thanks for all the info. Maxud is correct that the timing belt service at #4 says "Inspect water pump". I guess Honda assumes its not going to be replaced, although I don't know why someone wouldn't replace the water pump if they are doing the timing belt anyway.

Thanks again,
Rich

I had this come up, as well, and here was my take on it. This is just my opinion, and what I did. I am not going as far as to say you should do it too...it's up to you. You can't get all the coolant out during any drain and fill. If you remove the water pump you get more out than a regular drain and fill but still have the heater core, and a little left in the block. When the coolant service came up again, I gave it a radiator drain and fill figuring that it removed a bit more of the old coolant not drained at water pump service time.

That may have been unnecessary but it only took me a few minutes to do it and less than 2 gallons of coolant. If you're considering taking it in to have it done I wouldn't worry about it if the water pump was changed.

As far as the customer is concerned, a good tech would have reset maintenance minder item #5 with the scan tool so that it didn't come up again too soon. When I did my first timing belt I didn't have a bidirectional scan tool. Now, I do it for my customers when I do timing belt/water pump. As far as making money, a good tech will NOT reset it so that you come in again when it pops up the #5.
