I have 150,00 plus miles on my 2004 Honda Odyssey. I had the timing belt replaced at 120,000 and the dealer ship said I "did not need to replace the water pump" then which surprised me. I am into proactive maintenance and want to keep this car a long time what maintenance should I have done now. Shouldn't I get the water and fuel pumps replaced? I do a lot of highway driving and some in a small town. What other maintenance should i get done? I maintain the brakes and have had the drums turned. This car runs like a top and I want to keep it that way.

2004 Honda Odyssey Question: When (miles) should you replace fuel and water pump?

I like to see people do preventive rather that proactive maintenance. Water pump replacement is normally prudent to do when changing the timing belt, if its not giving problems now it is then expected to work trouble free until the next scheduled timing belt which will now be over 200,000 miles. I would also have recommended changing the cam and crankshaft seals and the tensioners and idler bearings. We have customers with over 400,000 miles on their cars and have never "broken down".
Fuel pump replacement is not needed as a maintenance item. Using a scan tool the fuel trim figure can be read off seeing if fuel needs to be added that may be a sign of fuel starvation/a failing fuel pump. Also putting a amp meter in the fuel pump circuit an looking at amp draw or better still looking at oscilloscope pattern may tell if the pump armature or brushes are failing.
Transmission fluid change and brake fluid flush con tribute to longitivity, also check belts and hoses periodically, original Honda hoses are better quality than some off brand replacement hoses.
