we had our 2001 Sienna in for a regular service. The shop owner, who has been incredibly honest in the past, called and asked if we had the timing belt changed at 90,000 miles (necessary since the car now has 120,000). It wasn't in their records. We didn't remember so we told them to go ahead and change it. They called back the next morning and said that it had already been changed, so they adjusted it. They charged us $125 to adjust it... Now, does the timing belt need adjusting or does it auto-adjust? I think he is charging us for the wild goose chase he started. Thoughts or knowledge would be appreciated.
