Product Overview
The 31100-RV0-A01 is a Honda OE-spec replacement alternator delivering 12V 130A output with a 6-rib (6PK) pulley, engineered for Honda Pilot, Odyssey and Ridgeline equipped with 3.5L V6 petrol engines. This Denso-pattern aftermarket unit matches the original charging-system specification for these large-capacity V6 platform vehicles.
Fitted with internal regulator design, this brand-new alternator is stocked in-house with a 1-year warranty and 30-day dispatch lead-time. The 130-amp high-output rating is factory-correct for stock electrical loads of 3.5L V6 powertrains, supporting multi-zone air conditioning, heated accessories, infotainment and factory electrical equipment for SUV, MPV and pickup models.
Key physical specs: net weight 5.65 kg, gross weight 5.95 kg, overall dimensions 240 x 180 x 170 mm, supplied inside neutral kraft inner carton.
The 3.5L V6 Engine Platform and 130A Charging System
The 3.5L V6 petrol engine is widely fitted across Honda Pilot, Odyssey and Ridgeline. These large-displacement vehicles carry heavier factory electrical loads, including multi-zone climate control and additional comfort accessories, which is why the charging system is rated at 130A rather than a lower output.
It is critical to distinguish alternator hardware between base-spec and higher-option vehicles. Some market-specific assemblies use lower amp output or a different pulley rib count. Those units are not directly interchangeable with this 130A-6PK alternator.
The 6-rib pulley matches the original accessory-belt layout for the Pilot, Odyssey and Ridgeline, driving alternator, water pump and power-steering pump. Installing a pulley with the wrong rib count will cause belt mis-tracking, slippage, premature belt wear and intermittent charging faults. Always cross-check against your old alternator before ordering.

Engine Compatibility and Cross Reference
This alternator fits Honda vehicles equipped with the 3.5L V6 petrol engines used in the Pilot, Odyssey and Ridgeline. Do not rely solely on vehicle model name for fitment validation; always verify engine code, old-part OE number, pulley rib-count and amp label on your original alternator.
| Vehicle | Engine Code | Notes |
|---|---|---|
| Honda Pilot | 3.5L V6 | SUV platform |
| Honda Odyssey | 3.5L V6 | MPV minivan |
| Honda Ridgeline | 3.5L V6 | Pickup truck |
Multiple Honda OE numbers appear across production batches and regional market specifications for this same alternator family. If your original unit bears one of the listed cross-reference numbers, 31100-RV0-A01 serves as a direct drop-in replacement.
What to Look for in a Replacement
Follow these five verification steps before placing your order to avoid wrong-part returns:
1. Check the amperage label on your old alternator: confirm it is rated for 130A. Lower-output units cannot substitute.
2. Count pulley ribs: this unit requires 6PK (6-rib). Units with a different rib count are incompatible for this accessory drive setup.
3. Confirm the engine family is the 3.5L V6. This alternator does not fit four-cylinder Honda engine families.
4. Match against OE / reference part numbers stamped on your original housing.
5. Weight cross-check: genuine matching unit weighs approximately 5.65 kg net; significant weight difference indicates wrong assembly.
Application Scenarios

Hobbyists with lightly modified vehicles retaining factory-style electrical systems.
FAQ
Q: Can I fit this alternator onto Honda four-cylinder engines?
A: No. Four-cylinder platforms utilise different alternator mounting points, pulley and terminal layout. Confirm engine code before ordering.
Q: My old alternator shows OE number 104210-1240, will 31100-RV0-A01 work?
A: Yes. These numbers belong to the same Denso alternator family for the 3.5L V6 platform, differing only by production revision and market specification. It serves as a direct replacement.
Q: What is the normal charging voltage after installation?
A: With the engine running at idle, battery terminal voltage should read 13.8V-14.5V; at 2000 rpm the target stabilises around 14.0-14.7V.
Q: Can I install this unit if my car has heavy audio or auxiliary-light modifications?
A: This is a stock-spec 130A alternator designed for factory electrical load. Heavy-draw accessories may exceed its capacity; consider a high-output upgrade solution in that case.
Q: What is your warranty and lead-time?
A: Goods are in stock with a 30-day dispatch lead-time. A 1-year warranty applies from installation date; warranty excludes damage caused by mis-installation, wrong belt tension, or vehicle-wiring faults.
In Practice
For technicians working on Honda 3.5L V6 platforms: Before removing the existing alternator, perform charging-system diagnostics. Measure battery terminal running voltage with a multimeter. Weak batteries, corroded ground connections or a faulty main harness can mimic alternator failure symptoms. Always disconnect the battery negative terminal before commencing removal work and wait several minutes for on-board system capacitors to discharge.
Take photos of wiring connectors and bolt positions during disassembly to avoid mis-routing during reassembly. Observe correct belt tension: 10-15 mm deflection when pressing the belt mid-span. Over-tightened belts accelerate alternator bearing wear; loose tension creates slipping and insufficient charging. Torque mounting bolts to Honda workshop-manual specifications.
Inspect the belt tensioner condition at the time of alternator replacement. Replace a worn or sticky tensioner together with the belt to prevent repeat failures. Inexperienced home mechanics are recommended to entrust replacement work to a qualified auto-electric repair shop. Incorrect wiring risks burning the alternator or vehicle-system components. After finishing, clear vehicle fault codes and perform a road test.
