Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
At how many miles should these be changed? I have a 2005 TL.

The 3.2L V6 engine on the 2005 Acura TL is driven by a Timing Belt. They recommend to replace it every 90,000 to 105,000 miles.
The repair book says at 60,000 miles, however, this is only recommended. The belt is inside the engine and can't be examined. I waited till just over 100,000 miles to do this on my 2005 TL because it was so expensive. I also replaced the water pump as suggested. I did not do this at Acura, but other repair shops had a similar price, about $800 for both items.
