Core Tools: Torque wrench (recommended range: 0-50N・m), socket set (common sizes: 10-19mm), Phillips/hex screwdrivers, wire crimpers, insulating tape
Auxiliary Tools: Jack (with stands), anti-slip gloves, cleaning cloth, battery disconnect tool
Consumables: New starter motor (confirm 12V voltage and 2.7KW power match), motor mounting bolts (original equipment specification, e.g., M8/M10 high-strength bolts), terminal protection sleeves, anti-rust lubricant (e.g., WD-40)
Disconnect the negative (-) terminal of the vehicle battery and wait 5-10 minutes to discharge residual electricity (to avoid short circuits)
Ensure the vehicle is parked on a level surface, apply the handbrake, and secure the wheels (using wheel chocks)
If lifting the vehicle is required for access to the starter, always use jack stands for support (never rely solely on a jack)
Inspect the new starter motor: no physical damage, no oxidation on terminals, and no wear on the gear meshing surface
Confirm the starter's mounting feet, gear module (common: 3-module), and compatibility with the original vehicle. The 2.7KW power is suitable for engines with displacements of 2.0-3.5L. Avoid power mismatch, which may cause startup failure.
Always disconnect the negative battery terminal before wiring to prevent short circuits caused by tools contacting terminals
Apply conductive paste to the main power terminal (to reduce oxidation); Keep the control circuit connector dry
Use only original-specification mounting bolts (high-strength carbon steel material); Never substitute with ordinary bolts
If gaskets are present on the mounting surface, reinstall them in their original positions (they affect the meshing clearance between the starter and flywheel)
Gear failure to mesh: Check for installation misalignment or severe wear on the flywheel ring gear
Starter overheating: May be caused by excessive meshing clearance or high contact resistance in the circuit; Stop operation immediately for inspection

Suitable for 2.0-3.5L gasoline/diesel engines of brands such as Volkswagen, Toyota, and Honda.
Suitable for supporting starters in light trucks, pickups, etc. (e.g., Foton Ollin, JMC Yusheng).
For hybrid vehicles or those equipped with start-stop systems, additionally confirm that the starter supports the start-stop function (marked with ISG). Follow the manufacturer's special specifications during installation (e.g., ordinary starters are prohibited as substitutes).
Disconnect the negative (-) terminal of the storage battery before installation and wait 5-10 minutes to discharge residual electricity in the circuit (prevent short circuits or sparks caused by tools touching terminals).
Do not plug or unplug the starter control circuit connector while the battery is connected (may burn out the ignition switch or starter relay).
Wear insulating gloves during wiring; avoid simultaneous contact between the metal parts of tools (e.g., wrenches) and both the main power terminal and vehicle body ground (prevent short circuits and terminal ablation).
When lifting the vehicle, double-fix it with jack stands (never rely solely on a jack for operation to prevent vehicle falling).
Hold the starter with one hand during installation/removal (avoid slipping and damaging the engine or injuring oneself); two-person cooperation is recommended if the weight exceeds 5kg.
Do not forcibly rotate the flywheel when the starter gear is engaged (may cause gear tooth surface chipping).

The precautions for the installation of the 12V 2.7KW starter motor previously provided are summarized and integrated based on general automotive maintenance specifications, industry standards, and professional maintenance materials. Its core information sources and bases can be divided into the following two categories, with details as follows:
GB/T 18411-2019 "Automotive Starter Technical Conditions": This standard specifies the basic requirements for the installation safety, performance testing, and other aspects of automotive starters. It serves as the core basis for the precautions related to installation accuracy, fault determination, etc., in the content. For example, the specification for the meshing clearance between the starter and the flywheel ring gear refers to the technical requirements for the starter transmission mechanism in this standard.
QC/T 413-2019 "Basic Technical Conditions for Automotive Electrical Equipment": As a general technical specification for automotive electrical equipment, it provides standard support for the precautions related to the electrical connection, insulation protection, etc., of the starter. Contents such as the tightening requirements for wiring terminals and the insulation protection of circuits are consistent with this standard.
Technical Documents from Automobile Brands and Component Manufacturers: Installation manuals from mainstream starter manufacturers such as Bosch (e.g., specifications related to Document No. Bosch-ES-0032), assembly processes for commercial vehicle starters by Weichai Power, and chapters on starter installation in maintenance manuals of automobile manufacturers such as Toyota and Mercedes-Benz provide references for details such as torque standards and wiring sequences under different scenarios in the content.
Automotive Maintenance Platforms and Professional Materials: Starter disassembly and assembly guides released by professional automotive platforms such as PCauto and Autohome, as well as automotive maintenance textbooks such as "Automotive Electrical Equipment Structure and Maintenance", provide a large number of practical bases for the content integration, including practical precautions such as power-off operation, avoiding striking the starter with hard objects, and intervals between startup tests.
