Product Overview
The WL2118300T is a Mazda OE-spec replacement alternator delivering 12V 80A output with a 2-groove (2PK) double V-belt pulley, engineered for Mazda vehicles using the WL diesel engine family. This Bosch-pattern aftermarket unit matches the original charging-system specification of these Japanese diesel 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 80-amp rating is factory-correct for the stock electrical load of these diesel vehicles, supporting starting-system recharging, lighting, and standard electrical equipment.
Key physical specs: net weight 5.2 kg, gross weight 5.5 kg, overall dimensions 240 x 180 x 170 mm, supplied inside neutral kraft inner carton.
The Mazda WL Diesel Platform and 80A Charging System
Mazda vehicles using the WL diesel engine family carry a compact charging-system architecture with a double V-belt driven alternator and internal regulator. The WL engine family covers 2.5-litre diesel applications on Mazda pickup and utility platforms.
This unit is specified as 12V 80A, matching the factory charging-system specification of these platforms. The 2-groove (2PK) pulley matches the original double V-belt accessory drive. Installing a single-groove or multi-rib pulley on a double V-belt drive will cause belt mis-tracking, slippage, premature belt wear and charging faults. Always cross-check against your old alternator before ordering.

Engine Compatibility and Cross Reference
This alternator fits Mazda vehicles using the WL diesel engine family. Do not rely solely on the vehicle model name for fitment validation; always verify engine code, old-part OE number, pulley type and amp label on your original alternator.
| Make / Model | Engine | Notes |
|---|---|---|
| Mazda (WL diesel engine platform) | WL diesel family (verify engine code) | Verify 2PK double V-belt, 80A and mounting layout |
Multiple Mazda, Bosch and supplier 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, WL2118300T 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 80A. Different amp ratings are not interchangeable.
2. Count pulley grooves: this unit requires a 2PK double V-groove pulley. Single-groove and multi-rib pulleys are not interchangeable with this accessory drive setup.
3. Confirm the exact Mazda model, engine code and production year of your vehicle.
4. Match against OE / reference part numbers stamped on your original housing.
5. Weight cross-check: genuine matching unit weighs approximately 5.2 kg net; significant weight difference indicates wrong assembly.
Application Scenarios
Independent repair shops and Mazda specialists servicing WL diesel models across Asia-Pacific, Africa, Latin-America, Europe and the Middle East.
Parts counters and jobbers stocking Japanese diesel charging-system components.
Vehicle owners restoring and maintaining original-spec Mazda diesel models.
Used-car export traders supplying pre-owned Mazda diesel vehicles to global secondary markets.
Owners with standard electrical loads who require a factory-spec charging system.
FAQ
Q: Which Mazda models does this alternator fit?
A: It fits Mazda vehicles using the WL diesel engine family. Always verify against the OE number, pulley and mounting layout of your original alternator before ordering.
Q: Is this a double V-belt alternator?
A: Yes. This unit has a 2-groove (2PK) pulley for double V-belt drives. It will not fit single V-belt or multi-rib belt systems.
Q: My old alternator shows OE number A002TA1099 or WL2118300A, will WL2118300T 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, output voltage should read approximately 13.8V-14.5V on this nominal 12V system.
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 Mazda WL diesel vehicles: 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 Mazda 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.
