Does the honda crosstour have a timing belt or chain?

Whether or not You've got a timing chain or timing belt will depend on which engine You've got in Your Honda Crosstour. The 2.4 L 4Cylinder engine uses a timing chain while the 3.5 L V6 has a timing belt. If You've got the belt then You'll have a bit of maintenance involved there. The belt should probably be replaced every 80,000 miles at least but You can potentially make it to 120,000 miles without needing a replacement. If You've got the chain then You don't need to worry about replacing the chain at all unless there is a mechanical failure. The chain stays lubricated by Your engine oil and doesn't need any special attention -
