2001 civic 110k service?

It's controversial, but I am with the people who believe the water pump should be changed at the same time. Some have kept the original water pump over 200K miles, but I don't think that's the smart way to bet. It is reasonably priced and the labor to change it once the timing belt is off is small. Same thing on the crank and cam seals - cheap and easy at that point, although they are a rare failure. Also the seals won't destroy your engine if they fail, like the water pump can. My belief was sealed when a member of the Volvo group reported his water pump seized a year after he had the belt replaced, and it cost him bent valves. Seals optional, water pump not.

There's also a belt tensioner - two in some engines - that is probably getting pretty ragged (the sealed bearing will sound like an old roller skate wheel) after 100K. It is in the same price range as the water pump, but if you can afford it the peace of mind is worthwhile.

Thanks. I was definately going to change the water pump after reading other sources. I hadn't thought of the tensioner and will get a price on it. Since I plan to put 300,000 ( I commute 33k per year) miles on this car, I want to keep it in good service and preventive maintenance is always cheaper than repairs.
