What is a tensioner on Honda Odyssey?
How does the drive belt tensioner work? It is bolted to the front of the engine, and the flat side of the drive or serpentine belt rests tightly against the belt tensioner pulley. When the belt is driven, the belt tensioner pulley constantly rotates, keeping tension on the belt.
Where is the routing information on a drive belt?
Locate the Belt Routing Diagram. The serpentine belt routing diagram is usually located on a tag in the engine compartment. If it is not found there, it can be accessed in a repair manual, such as Chilton’s Online Repair Manual. A quick sketch or a photo of the drive belt system would also suffice.
What is a tensioner pulley?
Tensioner pulleys provide precise guidance and constant belt tension in the belt drive. They can either be mounted rigidly or combined with the tensioning elements to belt tensioners. Tensioner pulleys increase the wrap angle on belt drives and thereby transmit higher performance.
Is the serpentine belt the same as the timing belt?
Timing Belt. Don’t get confused—a serpentine belt is not the same thing as a timing belt. The timing belt is located inside the engine and keeps the crankshaft and camshaft in sync. This ensures that the engine intake and exhaust valves open and close in time with the pistons so the engine runs smoothly.

The tensioner arm should move smoothly and freely. Solution: If you notice a binding, sticking or grinding tensioner arm, the tensioner should be replaced.
What is the serpentine belt routing?
An example of a serpentine belt routing diagram (drive belt diagram). The serpentine belt wraps around several engine-driven accessories fitted with pulleys, as well as the engine’s crankshaft pulley. Whenever the vehicle is running, the engine’s crankshaft pulley turns the serpentine belt.
Where is the tensioner for the serpentine belt?
The tensioner is located on the outside of a serpentine belt which is the smooth side of the belt. It puts tension on the belt to keep it tight. The serpentine belt stretches over time, so the tensioner puts more tension on it to keep it tight.
When should the timing belt be replaced on a Honda Ridgeline?
Timing belts are replaced as part of scheduled maintenance, usually every 60,000 to 100,000 miles.
