What causes the timing belt and idler to fail?
Misalignment of the timing belt can cause premature failure of the idler pulley or the pulley on the tensioner, as well as the belt. Generally, this indicates that the tensioner or idler is not attached to the mounting location on the engine correctly or the bearings for the tensioner, idler or both, have worn and have excess “play”.
What causes the idler pulley on a tensioner to fail?
The idler pulley accounts for about half of all tensioner failures. Misalignment of the timing belt can cause premature failure of the idler pulley or the pulley on the tensioner, as well as the belt.
When to replace the timing belt and tensioner?
Replace if any movement is detected. With the timing belt removed, check both the idler and tensioner pulleys for roughness when rotating the bearing. The idler & tensioner should spin freely and smoothly. Replace bearing (s) if roughness is determined.
How do you change timing belt on Honda Odyssey?
Going from the memory. Remove the serpentine belt and tensioner. Remove crank pulley. Remove the lower timing belt cover. Thread the rod to hold down the tensioner pulley. Undo 2 bolts that hold the hydraulic tensioner. Then reassemble. No need to mess with top end at all. No need to worry about timing marks, as the belt stays put.

How do you unbolt the timing belt tensioner?
In the service manual, it describes a step that looks completely superfluous, where you remove one of the battery hold down rods and thread it into the timing tensioner pulley, allowing you to unbolt the timing belt tensioner, while tension on the timing belt remains in place. This is exactly what you need to do. Going from the memory.
When to replace a serpentine belt tensioner?
Repair Topics > Belts Serpentine & Timing > When to replace serpentine… Let’s get this straight from the get-go, a serpentine belt tensioner doesn’t last the life of the vehicle. In fact, most start to show serious wear right around the 100K mile mark. You may think a worn tensioner just means your belt loses tension; you’d be wrong.
