Steve; the reason your data was different from mine is that I looked very thoroughly in the Edmunds maintenance schedule for this vehicle; and could not find a single mention of the timing belt replacement schedule. I went back and forth through that schedule repeatedly, and looked at both 60,000 and 90,000 miles (the two commonly used timing belt replacement intervals) and couldn't find it. And that's why I answered 60,000 miles. But after reading your post, I went back to the 90,000 mile schedule and found it; right where it is supposed to be. Turns out that I had not previously looked at the 90,000 mile schedule; but had instead looked at the one below it.
This is a good example of why it is sometimes helpful to have multiple posters answering questions. I apologize to you, and to the person who asked the question, for my error.
