2022 Honda Pilot Serpentine Belt Routing & Replacement Guide

As an ASE-certified master technician, I’ve seen countless drive belts wear out, stretch, and snap, leaving drivers stranded on the side of the road. Replacing the serpentine belt on your 2022 Honda Pilot (equipped with the 3.5L V6 engine) is an essential maintenance item that you can often tackle in your own driveway with the right tools and information.

Below is your complete guide to the 2022 Honda Pilot serpentine belt, including part numbers, routing, and replacement procedures.

Quick Answer: 2022 Honda Pilot Serpentine Belt Specs

Before you dive under the hood, here are the exact specifications and part numbers you need for the 3.5L V6 engine in the 2022 Honda Pilot. Note that since this vehicle features Electric Power Steering (EPS) and a timing belt-driven water pump, the serpentine belt is relatively short and only drives the alternator and A/C compressor.

• Belt Length: 65.6 inches (approximate)
• Rib Count: 6-rib design
• OEM Belt Part Number: Honda 31110-RLV-A02 (or 31110-RLV-A01)
• Aftermarket Cross-References: Gates K060656, Continental Elite 4060656, Dayco 5060656
• Auto-Tensioner Assembly Part Number: Honda 31170-RLV-A01 (includes tensioner pulley)
• Idler Pulley Part Number: Integrated into the tensioner assembly for this application.

Belt Routing

Pro-Tip: Always take a clear photograph of your existing belt routing with your smartphone before you remove the old belt. It is the best reference you can have if you get confused during reinstallation.

Because the 2022 Honda Pilot utilizes a modern J35 V6 with EPS and an internal timing belt-driven water pump, the serpentine belt routing is quite simple compared to older vehicles. The ribbed side of the belt will ride on the grooved pulleys (Crankshaft, Alternator, A/C), while the smooth side rides on the tensioner pulley.

Here is the step-by-step text description of the routing path:

1. Start by looping the ribbed side of the belt around the bottom Crankshaft Pulley.
2. Route the belt straight up and over the grooved Alternator Pulley at the top front of the engine.
3. Bring the belt straight down from the alternator and loop it under the grooved A/C Compressor Pulley at the bottom front.
4. Finally, pull the smooth back side of the belt around the smooth Auto-Tensioner Pulley (located between the crankshaft and alternator) to complete the loop.

How to Replace the Serpentine Belt

Replacing the drive belt on the 2022 Honda Pilot is straightforward but can be tight on space.

1. Gather your tools: You will need a dedicated serpentine belt tool or a long-handled 3/8" drive breaker bar (some tensioners require a 14mm or 19mm socket on the tensioner bolt; verify your specific tensioner casting).
2. Access the tensioner: Open the hood and locate the auto-tensioner on the passenger side of the engine bay.
3. Relieve tension: Place your tool on the tensioner pulley bolt or the square 3/8" drive slot (depending on the OEM/aftermarket tensioner design) and slowly rotate it counter-clockwise (towards the firewall) to compress the internal spring and relieve belt tension.
4. Remove the belt: Slide the old belt off the alternator pulley first, as it is the easiest to reach. Then, carefully release the tensioner back to its resting position and pull the belt completely out of the engine bay.
5. Install the new belt: Route the new belt following the path described above (Crank -> A/C -> Alternator), leaving the tensioner for last.
6. Apply tension: Compress the tensioner again, slip the smooth side of the belt onto the tensioner pulley, and slowly release the tool so the tensioner applies pressure to the new belt. Inspect all pulleys to ensure the belt ribs are seated perfectly in the grooves.

Replacement Interval

For the 2022 Honda Pilot, Honda recommends inspecting the serpentine belt during your regular "B" service intervals (Maintenance Minder system). However, as a rule of thumb, modern EPDM belts should be thoroughly checked starting at 60,000 miles and typically replaced between 75,000 and 90,000 miles. Always replace the tensioner assembly if you notice a bouncy tensioner arm or a noisy pulley bearing when doing the belt.

Signs of a Failing Belt or Tensioner

Don't wait for the belt to snap. Keep an eye (and ear) out for these common warning signs:

• Squealing or Chirping Noises: Especially on a cold startup or when accelerating. This indicates a loose belt, a stretched belt, or a failing tensioner spring.
• Visible Wear: Look for deep cracks (more than 3 per inch), missing chunks of ribbing, or a shiny, glazed appearance on the ribbed side.
• Accessory Malfunctions: If the belt is slipping, your A/C might blow warm, or your battery warning light may illuminate on the dashboard because the alternator isn't spinning fast enough.
• Rattling from the Passenger Side: A failed hydraulic/spring auto-tensioner will often vibrate violently, creating a metallic rattling noise.
