Product Attributes

Product Details

Product Overview

The 104210-3880 is a Toyota OE-spec replacement alternator delivering 12V 100A output with a 7-rib (7PK) pulley, engineered for Toyota Camry, Highlander and RAV4 models with 2.4L petrol engines. This Denso-pattern aftermarket unit matches the original charging-system specification for these popular mid-size sedan and SUV platforms.

Fitted with internal regulator design, this brand-new alternator is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The 100-amp rating is factory-correct for stock electrical loads of these platforms, supporting climate control, heated accessories, infotainment and factory electrical equipment.

Key physical specs: net weight 5.65 kg, gross weight 5.85 kg, overall dimensions 240 x 180 x 170 mm, supplied inside neutral kraft inner carton.

The 2.4L Engine Platform and 100A Charging System

The Toyota Camry, Highlander and RAV4 share the 2.4L petrol engine family in several production generations, and the 100A 7PK alternator covers these applications, which keeps one part number serving multiple workshop jobs across the three model lines.

This Denso-pattern unit is specified as 12V 100A, matching the factory charging-system specification of these platforms. The 7-rib pulley matches the original accessory-belt layout, driving alternator, water pump and power-steering pump. Installing a pulley with the wrong rib count (for example a 6PK unit) will cause belt mis-tracking, slippage, premature belt wear and charging faults. Always cross-check against your old alternator before ordering.

Technical Specifications

Engine Compatibility and Cross Reference

This alternator fits Toyota Camry, Highlander and RAV4 vehicles equipped with the 2.4L petrol engine. 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.

Multiple Denso and Toyota 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, 104210-3880 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 100A. Different amp ratings are not interchangeable.

• 2. Count pulley ribs: this unit requires 7PK (7-rib). Units with a different rib count are incompatible for this accessory drive setup.

• 3. Confirm engine code (2.4L, commonly 2AZ-FE) and production year match the original fitment list.

• 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

• Independent repair shops and Toyota specialists servicing Camry, Highlander and RAV4 across Europe, Oceania, Asia-Pacific and Latin-American markets.

• Parts counters and jobbers stocking Japanese vehicle replacement electrical components for mid-size sedans and SUVs.

• Vehicle owners restoring and maintaining original-spec Toyota Camry, Highlander and RAV4 models.

• Used-car export traders supplying pre-owned Toyota vehicles to global secondary markets.

• Hobbyists with lightly modified vehicles retaining factory-style electrical systems.

FAQ

Q: Which Toyota models does this alternator fit?
A: It fits Toyota Camry, Highlander and RAV4 models with the 2.4L petrol engine. Always verify against the OE number, pulley and mounting layout of your original alternator before ordering.

Q: Is this a Denso-pattern alternator?
A: Yes. This unit matches the Denso-pattern charging system and carries the Denso numbers 104210-3880 / 104210-3890 together with Toyota OE numbers 27060-0H170 / 27060-0H200.

Q: My old alternator shows OE number 27060-0H170 or 104210-3890, will 104210-3880 work?
A: Yes. These numbers belong to the same alternator family, 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: What is your warranty and lead-time?
A: Goods are in stock with a 10-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 Toyota 2.4L 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.

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 Toyota workshop-manual specifications.

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.
