Honda Odyssey Serpentine Belt Diagram (2024)

Updated on April 21, 2023

Serpentine belts get their name from the way they look – like a serpent weaving around pullies to spread the engine’s power to the auxiliary systems. The working principle is the same for almost all vehicles, but the exact layout of the belt differs. In this article, we’ll focus on Honda Odyssey and provide a diagram of its serpentine belt.

The Honda Odyssey has a transverse-mounted engine, meaning that the serpentine belt is next to the front right wheel. It sits low in the engine bay, with only the power steering pump pulley visible at the top. The serpentine belt diagram for the Honda Odyssey sort of looks like a fat letter “Z” as you’ll see in the image we’ve provided.

Serpentine Belt Diagram for Honda Odyssey

The following diagram shows you what the serpentine belt looks like on a Honda Odyssey when looking at it from the front. Keep in mind that this is not the view you’ll have when looking at it in the engine bay.

The pulleys that the serpentine belt connects are:

Power steering pump
Belt tensioner
Alternator
Idler
Crankshaft
Air Conditioning Compressor

The crankshaft pulley is connected to the engine’s source of rotation power, and the serpentine belt uses it to power the auxiliary systems, namely the power steering pump, alternator, and air conditioning.

The belt tensioner is a passive element that allows the belt to self-regulate as it stretches or contracts over time. The idler is there to redirect the path of the belt so that other pulleys have enough contact with the belt.

If you follow the inside, threaded side belt with your finger or cursor, you’ll see that the idler and tensioner come in contact with the opposite, flat side. While on the Honda Odyssey it’d be a bit difficult, you can generally inspect the condition of the belt by looking at the exposed threads on one of these pulleys.

Bad Serpentine Belt Symptoms

The serpentine belt is one of the most important components in a car’s engine that helps to keep everything running smoothly. Unfortunately, it can suffer from wear and tear over time, leading to problems like slipping, cracking, or even breaking.

1. Loud Squealing Noises

One of the most common signs of a bad serpentine belt is a loud squealing noise coming from under the hood when you accelerate. This sound occurs because the loose belt begins to slip on the pulleys as you increase the engine’s speed, causing it to rub against other components and make a squeaking sound.

2. Vibrations

Another symptom of a bad serpentine belt is vibrations coming from the engine. This usually happens when the belt starts to slip on the pulleys, which causes them to move slightly. This can also lead to an increase in RPMs that you may feel through your feet or even in the steering wheel.

3. Smell of Burning Rubber

If you start to notice a burning rubber smell coming from under the hood, this could be another sign that your serpentine belt is failing. This occurs because the slipping belt begins to heat up as it rubs against other components, creating friction and ultimately producing a burning rubber smell.

4. Visible Cracks

If you pop the hood and inspect the serpentine belt, you may also be able to see visible cracks or other signs of wear and tear on its surface. This is a sure sign that it’s time to replace the belt before it completely fails.

Replacing the serpentine belt on a Honda Odyssey is relatively straightforward. Here are the steps to follow:

1. Disconnect the negative battery cable from the battery terminal and set it aside in a safe place away from any moving parts.

2. Pop open the hood and locate the tensioner pulley near the passenger side of the engine bay. This should be easy to spot, as it has a large, round center groove with an adjustable arm coming out of it at an angle.

3. Once these components have been identified, you will need to remove the old belt from both pulleys. This can be done with a ratchet wrench or by loosening the tensioner bolt with a socket wrench. Be sure to note how the belt was routed around all of the pulleys before removing it.

4. Once the bolt is removed, you can pull on the tensioner pulley to relieve any pressure. This should allow you to easily slide the serpentine belt off all of its pulleys.

5. With the old belt out of the way, take a look at your new belt and familiarize yourself with how it should be routed. Pay special attention to any grooves or notches in the belt that will need to fit into certain components for proper installation. Slip on a new serpentine belt following its path exactly as it was originally installed.

Make sure that it fits snugly against each pulley without kinking or slipping off while installing it. With the new belt in place, tighten the tensioner bolt with a socket wrench to secure it in position. Now turn on your engine and check for any slipping or kinking as you rev up the RPMs. If everything looks good, your serpentine belt replacement is complete!

6. Start threading the new belt onto each of its corresponding pulleys from left to right (or vice versa). Make sure that each groove and notch fits snugly into its respective component.

7. Once the new belt is threaded onto all of its pulleys, it’s time to reattach the tensioner pulley. Line up the hole in the arm with the bolt hole on the engine block, and then use a socket wrench to tighten it back into place.

8. Finally, reconnect the negative battery cable, and your serpentine belt replacement is complete! Hop in your Honda Odyssey and enjoy smooth sailing from here on out.

That’s it! You now know how to replace a serpentine belt on a Honda Odyssey – nice job! If you have any questions or need any more help with this repair process, don’t hesitate to consult your local mechanic for assistance.
