The installation of the 12V starter for Changan Automobile shall prioritize power-off safety, following the procedure of Positioning → Fastening → Wiring → Testing. The core requirements are meeting torque specifications, ensuring correct wiring, and proper lubrication, so as to avoid short circuits and component damage. The following are the general standard procedures and key points, applicable to mainstream Changan models (such as CS35/55/75, Eado, Yuesxiang, etc.). For specific torque values, refer to the maintenance manual of the corresponding model.
Safety and Power-offTurn off the vehicle engine, disconnect the negative cable of the battery (critical for preventing short circuits), and switch off the ignition. For models equipped with an engine control unit (ECU), this step is mandatory.
Tools and MaterialsPrepare socket wrenches (commonly 12–16mm), a torque wrench, flathead and Phillips screwdrivers, insulating tape, cleaning cloths, and high-temperature resistant grease (for the overrunning clutch and bushings).
Accessory VerificationConfirm that the model of the new starter matches the original one; inspect the overrunning clutch, solenoid switch, and wiring terminals for damage. Clean the mounting surface (the joint between the engine and transmission) to remove oil stains, rust, and impurities.
Reference to the Old UnitIf replacing the starter, record the positions of the fixing bolts and the routing of electrical connectors/terminals of the old starter to prevent incorrect installation.
Positioning and Pre-installation
Push the starter into the mounting position, ensuring that the drive gear aligns with the flywheel ring gear and the mounting holes are coaxial with the bracket holes on the engine side. Do not strike the starter; push it into place manually.
Apply a small amount of grease to sliding parts such as the drive bushing and helical spline to reduce running resistance.
Fastening the Fixing Bolts
Insert 2–3 fixing bolts and hand-tighten them initially (to prevent thread seizing).
Use a torque wrench to tighten the bolts symmetrically according to the torque specified in the vehicle maintenance manual (typically 18–25 N·m; e.g., approximately 22 N·m for Changan CS75). Over-tightening may cause housing deformation, while under-tightening can lead to vibration.
Electrical Wiring Connection (Follow the Exact Sequence)
First, connect the thin control wire connector on the solenoid switch (mostly a waterproof buckle; confirm locking by hearing a "click" sound).
Then, connect the main power cable (thick wire, connected to the large terminal of the battery positive electrode), fasten it with a nut and add a lock washer to ensure no looseness.
When routing the wires, keep them away from high-temperature and moving components (such as the exhaust manifold and pulley) to prevent abrasion and short circuits.
Power Restoration and Inspection
Confirm that all connectors and wires are securely fastened, no tools are left behind, and reconnect the negative cable of the battery.
After power-on, first perform a no-load test: turn the key to the "START" position; the starter should run smoothly without abnormal noise or slipping. Then conduct a start-up test: the engine should ignite smoothly, and the starter must disengage from the flywheel ring gear immediately after the engine starts.
These precautions are formulated in accordance with Changan Automobile's original factory maintenance specifications and industry standards, covering four core dimensions: safe operation, component protection, electrical specifications, and test verification. They are designed to prevent starter damage, vehicle short circuits, or potential safety hazards caused by improper installation.
Before installation, the negative cable of the battery must be disconnected and the ignition switch turned off. For models equipped with engine anti-theft systems or intelligent start-stop systems, wait 5–10 minutes after power-off to allow capacitors to discharge completely before proceeding, so as to prevent burnout of electronic components.
Live plugging or unplugging of wire connectors is prohibited throughout the process. Ensure the ignition switch is in the off position when connecting wires.
When pushing the starter into the mounting position, ensure that the drive gear is aligned with the flywheel ring gear and the mounting holes are coaxial. Striking the starter housing or solenoid switch is strictly prohibited, as this may cause deformation of internal rotors and coils, as well as jamming of the overrunning clutch.
Fixing bolts should be hand-tightened initially before being fastened with a torque wrench. Do not directly tighten them with an air impact wrench, to avoid thread slipping or housing cracking.
Apply only a small amount of high-temperature resistant grease to sliding parts such as the helical spline of the overrunning clutch and the drive bushing, with the dosage sufficient to cover the contact surfaces—do not over-lubricate.
Electrical components (brushes, wiring terminals, coil windings) must not come into contact with grease or moisture, otherwise poor contact, short circuits, or aging of insulation layers may occur.
First connect the thin control wire connector on the solenoid switch (ensure the waterproof buckle is locked in place with a "click" sound), then connect the thick main power cable. Reverse the sequence during disassembly to prevent damage to components from high-current sparks.
The main power terminal should be fitted with a lock washer; after fastening, shake it by hand to confirm no looseness. Route the wires away from high-temperature and moving components (such as the exhaust manifold and pulley), and secure them with cable ties to prevent abrasion of insulation layers and subsequent short circuits.
The torque of the starter fixing bolts shall be subject to the maintenance manual of the corresponding model (typically 18–25 N·m for mainstream Changan models). Excessive torque may cause housing deformation, while insufficient torque can lead to abnormal vibration noise during startup and even bolt detachment.
The torque of the terminal nuts should be controlled within 8–12 N·m to prevent terminal deformation or wire breakage.
After restoring power supply, first perform a no-load test: turn the key to the "START" position; the starter should run smoothly without metal friction noise, and the drive gear should extend and retract normally. The no-load running time shall not exceed 5 seconds to prevent overheating and burnout of the coil.
After confirming normal no-load operation, conduct a start-up test: the engine should ignite smoothly; the starter must disengage from the flywheel ring gear immediately after startup without any "gear clashing" sound. If startup fails, cut off the power supply immediately for troubleshooting—do not attempt repeatedly.

Original Factory Maintenance Manuals for Various Changan ModelsThese manuals cover the starter disassembly and assembly chapters of mainstream Changan models, including CS35/55/75, Eado, Yuesxiang, BenBen, etc. The core contents include power-off procedures, bolt torque parameters (18–25 N·m), wiring sequence, no-load/start-up test specifications, etc., serving as the primary source of the content. For example, the Changan CS75 maintenance manual clearly specifies the torque of starter fixing bolts and the wiring connection requirements for the solenoid switch.
Changan Automobile Technical Service BulletinsThese bulletins specify special installation requirements for starters equipped on models with start-stop systems and intelligent anti-theft systems, such as the capacitor discharge waiting time after power-off and the model matching requirements for dedicated starters.
