Auto Alternator 27060-23010 27060-23070 DAN960 LRB00471 Fits Yaris Vitz Citroen Nemo

I. General Safety Preparation and Tool List

Core Safety Prerequisites

Required Tools

II. General Disassembly Steps (Removing the Old Alternator)

Create Adequate Working Space

• Toyota Yaris / Vitz: Remove the air cleaner housing, intake pipe and engine decorative cover. For some models, it is necessary to remove the right front wheel and wheel inner liner to work from underneath the vehicle.

• Citroën Nemo: Remove the engine decorative cover and part of the intake piping. Remove auxiliary components if necessary.

Disconnect the Wiring Harness (Sequence Must Not Be Altered)

Belt and Tensioner Operation

• Automatic tensioner type: Use a special tool to press the tensioner and release the belt tension slowly. Remove the belt and take photos to record its routing.

• Manual adjustment type: Loosen the adjustment bolt first, then the main mounting bolt. Swing the alternator to slacken the belt before removal.

Remove Mounting Bolts

• Toyota Yaris / Vitz: Remove the adjustment-side bolts first, then the main pivot bolt (commonly 12mm and 14mm). Take out the old alternator smoothly.

• Citroën Nemo: Remove auxiliary bolts according to the bracket layout, then the main mounting bolt, avoiding collision with surrounding components.

III. Model-Specific Installation Steps (Key Differences)

1. Toyota Yaris (Including Mainstream Versions Such as XP210)

2. Toyota Vitz (Based on the Old Yaris Platform)

• Installation and Positioning: Fit the new alternator, pre-tighten the main pivot bolt and adjustment arm bolt, leaving room for slight swinging.

• Belt Tension (Manual Adjustment Type): After fitting the belt, pry the alternator outward to tension it. The standard deflection is 5–10mm when pressing the middle of the belt with a finger. Tighten the adjustment bolt first, then the main pivot bolt.

• Wiring and Final Assembly: Same as Yaris. B+ nut torque: approx. 10N·m. Ensure the control connector is fully locked.

3. Citroën Nemo

• Installation and Positioning: Align the new alternator with the mounting holes, pre-tighten the main bolt and auxiliary bracket bolts. Ensure the alternator pulley is aligned with the crankshaft pulley and A/C compressor pulley.

• Belt and Tensioner: For models with an automatic tensioner, route the belt as recorded, press the tensioner to reset, then check that the belt is properly seated. For manual adjustment models, adjust tension to a deflection of 5–10mm.

• Wiring Connection: Clean the B+ terminal and tighten to approx. 10N·m. Lock the control connector securely. Route the wiring harness away from the exhaust pipe and rotating components.

• Final Assembly: Reinstall all removed components. Check that no tools are left behind and that no pipes are crushed.

I. General Core Safety Prohibitions (Applicable to All Three Models, Must Be Strictly Followed)

Mandatory Power Disconnection Throughout the Operation

Work Only After the Engine Has Cooled Completely

Maintain Complete Records of Component Positions

Tool and Protective Equipment Standards

II. General Precautions for the Disassembly Stage

Expand Working Space First; Forcible Prying Is Strictly Prohibited

• Toyota Yaris / Vitz: On most models, it is necessary to remove the air cleaner housing, intake pipe, and engine decorative cover. On some model years, the right front wheel and wheel inner liner must be removed to perform work from underneath the vehicle. Forcible prying from above will break intake pipes, scratch the condenser, and tear wiring harnesses.

• The sources of these precautions fall into three categories: core authoritative sources, supplementary reference sources, and practical integrated sources. The detailed source tracing and verification basis are as follows.

• I. Core Authoritative Sources (Core of Technical Parameters and Specifications)

• Toyota Service Manual

• Applicable to Toyota Yaris (including XP210 and other mainstream variants) and Vitz. It covers the complete alternator disassembly and assembly procedures, bolt torque specifications (such as 25N·m for the main pivot bolt and 9.8N·m for the B+ nut), wiring harness connection sequence, special service tool requirements, and other key specifications. For example, the service manuals for the Camry XV30 and Yaris XP210 clearly define the step-by-step procedures and safety standards for alternator assembly replacement. The corresponding model-year manuals can be retrieved via the Toyota Technical Information System (TIS) and professional automotive repair databases.

• Citroën Service Manual

• Applicable to the Citroën Nemo. It specifies the alternator mounting hole positions, pulley alignment requirements, B+ terminal torque specifications, and pipeline/wiring harness clearance guidelines, serving as the core authoritative basis for operations on the Nemo model.

• Toyota & Citroën Official Technical Training Materials

• Toyota’s advanced after-sales technician training textbooks and Citroën technical service documents emphasize safety specifications including power disconnection before operation, belt tension adjustment, and wiring harness protection. These materials supplement details not fully elaborated in the service manuals and ensure all operations comply with the official technical standards of the respective brands.
