I own a 1998 Honda Civic EX Sedan. I drove my car for 110k miles, 120k miles, 130k miles, etc. Many people told me that I should be thinking about getting the belts changed.
I finally decided to get all four belts (timing, alternator, compressor, power steering) and the water pump changed at 146,800. It costed $384 where I live in Michigan.
When I requested the parts back, I found that I could have gone longer. Considering they recommend 105k, I got a good run.
Perhaps these new belts can get me 150k miles.
