I have a 2006 HAH, which now has 92,000 miles on it.
I am wondering what is the recommended mileage interval for
changing the timing belt?

 

I seem to remember something like 84 months or 105,000 miles. But, I don't have my owner's manual handy to verify that. Have you looked into your own owner's manual yet?

 

Yes, that's right....I checked with the dealer today, and they said
105,000 mi. Will replace, at that time, the timing belt, tensioners, water pump, cam and crank seals, which comes in a "kit" on some websites.
(Since you have the car apart, its just handier at that time to change the water pump and seals at that time.

Timing belt replacement is not something I envy the dealership for, better them than me. With the tranverse mounted engine it's a bear getting at things down the side, in close quarters. And there's lots of tricky alignment, heavy torque values, and so on. I believe one of the engine mounts has to be partially removed, as a belt is captured by it. At least that is the case on some models. And they are right: it is an opportune time to replace other things in there. It might be a good time to replace the exterior accessory belts while they're at it: alternator, power steering, AC, and what have you.
