Wow, I'm impressed by the fearlessness that you all possess in keeping your original water pumps in the car - even when you change timing belts! It would drive me nuts to know that all I had to do was pull 5 bolts and I could have avoided tearing into the motor, again. I'm not a grade A mechanic and with two little kids my schedule doesn't allow for a lot of sudden car work. When I can afford a sick day to work on the car, I take it, lol.

That said, my Ody is at 136k with original timing belt and water pump and tensioner, etc. I planned on replacing it this week but my schedule won't allow it. In any case, it's on the docket and will get changed, all of them. I will cross my fingers at that time that I won't have premature failure of one of the components because I bought cheap aftermarket parts. I'm betting on the supply chain all using the same cheap manufacturer and simply marking up the parts based on "name brand" recognition.

I think I'd be more worried about cheap parts failing. If you don't change it you don't have to touch any coolant. With that said, I did replace the pump in mine with OEM parts.
 
I replaced the timing belt for the 3rd time (318k miles) and the OE Honda water pump was still feeling like new so I still opted not to replace. Also, realize that I have a brand new Honda water pump sitting on the shelf in my workshop. I read in the forum of water pumps failing however they were usually aftermarket pumps. IMO, if you properly maintain your coolant then the OEM pump should last and proactively replacing with a poor quality aftermarket pumps will actually cost you more in the end and during the TB replacement.
 
This makes so much sense when doing *any* proactive part replacement. Use OEM or equivalent or don't bother at all. If something is already broken, then save some money with aftermarket if you are inclined, especially if the OEM gave in early. Otherwise you are doing harm to the car by putting aftermarket parts as proactive maintenance. This is pretty simple concept but lot of us just don't get it.
 
My tensioner is still in great shape after 14 years and 318k miles. So was the water pump. The front TB idler pulley however had a tiny bit of bearing play. I would have replaced if I had had one on the shelf. Something to watch and listen for now. If you are proactively replacing parts, use only Honda.
Cheers!
 
Ideal situation for you would be then to use another vehicle to drive to local Honda dealer and (hopefully) pick up the bearing in the middle of the job.

This type of approach on such a major job makes it almost impossible to deploy at a garage. There you need parts on hand if you don't want to tie up the bay until the part is delivered.
 
All good info,.. thanks to all contributors and readers.....But I guess what I am really after, is some opinion on the likelihood of sudden catastrophic WP failure mode causing the timing belt to break/skip/or strip, and thus ruining/severely damaging the engine. I was warned about this by a mechanic, and I believe it is theoretically possible, but not probable.....but hey...I'm not a professional...just trying to understand the nature of the beast a little bit better.

My 2007 just had that happen everybody told me I should have heard noises and stuff but literally my truck was fine I picked my kids up from school went to the gas station and when I shut it off I started gushing coolant everywhere and turns out that it was like a huge failure and now I have to get engine work done on top of a new timing belt and water pump. And it really sucks because I had it scheduled to be replaced next month because it was nearing 200,000 I just hit 180

Are you sure it's the water pump and not a busted radiator hose? :unsure:

Doesn't sound right. When water pumps go bad, they tend to leak but not gush. If your WP seized up, busting the Timing Belt, then you have far more serious problems like bent valves.
I'm hoping kernel is right, and you have a cheap fix like a new hose and a gallon of antifreeze.
