Power Disconnection: First disconnect the battery negative (-) cable, wait 5 minutes to ensure complete discharge (avoiding short circuits from residual capacitor voltage). Wear insulated gloves and safety goggles during operation to prevent electric shock or part splashing.
Vehicle Fixation: Park on a flat surface, engage parking brake, use wheel chocks. Manual transmission: shift to 1st gear; automatic transmission: shift to P position to prevent accidental movement.
Environment & Cooling: Clear engine bay work area of debris, ensure engine is completely cooled (wait 15 minutes if recently operated) to avoid burns.
Electronic System Protection: For Hongqi models with CAN bus systems, turn off all electrical devices (lights, air conditioning) before power disconnection to prevent electronic module errors after restart.
Socket wrench set (8mm, 10mm, 12mm, compatible with starter mounting bolts for both brands)
Torque wrench (0-50Nm, ensuring bolt tightening precision)
Insulated tools (insulated pliers, screwdriver, preventing electrical short circuits)
Cleaner (removing oil/ rust), high-temperature grease (optional, for mounting surface sealing)
Label paper, marker (marking wire positions), cloth/towel (cleaning)
Multimeter (electrical pre-checks)
Model-specific Compatibility:
Nissan: Check part number (e.g., Nissan OEM 23300-XXX, must match original), confirm clockwise (CW) rotation, compatible with Nissan HR16, MR20 engine flywheel rings.
Hongqi: Compatible with CA4GB, CA647 engines, confirm starter terminal layout (B+, S terminals) matches vehicle wiring harness to avoid CAN bus compatibility issues.
Mechanical & Electrical Checks:
Manually rotate starter gear: should turn freely without binding, no tooth wear
Check solenoid housing: no deformation, terminals no oxidation
Measure solenoid coil resistance with multimeter (normal range: 3-8 ohms, no short/ open circuit)
Mark each wire's connection to starter terminals (B+ main power, S control terminal, ground wire) with label paper. Terminals function similarly between brands but positions may differ.
Disconnection Sequence:
Remove B+ terminal main power cable (thick wire)
Remove S terminal control wire (thin wire, red for Nissan, blue for Hongqi)
Remove ground wire (Nissan often connects to starter housing, Hongqi some models connect to body ground point)
Starter typically secured by 2 bolts on engine block/ flywheel housing:
Nissan: Bolts usually 12mm, loosen diagonally (avoiding unilateral stress deformation)
Hongqi: Some models have mounting brackets, remove bracket bolts (10mm) first, then starter body bolts
Store bolts properly, record specifications for reuse or replacement.
Thoroughly clean engine flywheel housing mounting surface and starter flange, removing oil, rust, old gasket residue to ensure flat contact (preventing loosening or abnormal gear engagement). Check mounting hole threads: Nissan threads prone to vibration damage, Hongqi cast iron surfaces generally more stable. Apply small amount of high-temperature grease (optional) for better sealing and reduced vibration.
If original starter had gaskets, install new starter with same position and quantity (Nissan some models no gasket, Hongqi some models have one). Align new starter with mounting holes, gently push to engage gear with flywheel, rotate slightly if needed to align. Insert bolts, hand-tighten ensuring threads fully engaged.
Nissan: Attach ground wire to starter housing ground terminal, tighten to 7-10Nm.Hongqi: Connect ground wire to specified body ground point (left engine bay ground post), ensure clean contact to reduce voltage drop.
Connect S terminal control wire to starter's marked terminal, ensure tight contact (no oxidation/looseness), tighten to 5-8Nm. For Hongqi, route control wire away from engine heat sources (exhaust pipes) to prevent insulation aging.
Manually rotate engine crankshaft (via pulley), observe starter gear and flywheel ring gear engagement clearance: normal range 2-4mm, uniform without binding. Adjust if necessary: Nissan can slightly adjust starter position, Hongqi check gasket integrity.
Connect battery in sequence: first positive (+), then negative (-).
Test Sequence:
Initial Start: Start engine (max 5 seconds), observe smooth operation, no abnormal noise
Voltage Check: Measure battery voltage during start (≥10V normal), after running (13.8-14.2V charging voltage, standard for both brands)
Multiple Starts: Perform 3 start-stop cycles, verify consistent response
Hongqi Additional Check: After starting, check instrument panel for fault lights; clear CAN bus error codes with diagnostic tool if necessary.
No Live Operation: Never connect/disconnect wires without battery disconnection, risking damage to Nissan starter relay or Hongqi ECM.
No Impact: Avoid striking starter (internal coils and gears are precision components, prone to deformation or contact damage).
Connection Sequence Mandatory: Follow "ground → control → main power" for electrical connections, and "positive first, then negative" for battery. Reversed sequence on Hongqi may trigger anti-theft lock.
Nissan:
Some older models (e.g., Sylphy Classic) share starter and generator ground points; ensure secure connection to prevent weak starting.
Non-OEM starters may cause compatibility issues with Nissan ECM, resulting in delayed starting.
Hongqi:
Models with auto-start-stop systems (e.g., H5 hybrid) have dedicated control lines; verify starter supports this function and avoid mixing with standard S terminal wiring.
Hongqi electrical systems are voltage-sensitive; use diagnostic tools to clear fault codes after installation for proper starter recognition.
Weak Starting: Check battery voltage (≥11.5V), ground connections; for large displacement engines (e.g., Hongqi 2.0T), verify starter power match to prevent overload.
Starting Noise (Clicking): Usually gear misalignment or loose bolts; adjust clearance and tighten bolts (Nissan: slight position adjustment; Hongqi: check gasket).
No Start: Measure S terminal voltage during starting (should be 12V):
No voltage: Nissan: check starter switch, relay; Hongqi: check ECM control signal (may need diagnostic tool).
Voltage present: Starter internal coil failure, replace needed.
Overheating: 1.2KW starters have limited heat dissipation; if running longer than 5 seconds, check gear engagement tightness or ground conditions.

Nissan Official Standard: The Nissan Service Manual explicitly stipulates: "Before removing the starter, the ignition switch must be turned to the LOCK position first, then disconnect the battery negative (-) cable, followed by the positive (+) cable. Wait for at least 30 seconds to ensure the circuit is fully discharged."
Hongqi Official Standard: The Hongqi Vehicle Maintenance Manual requires: "Before inspecting or repairing the electrical system, disconnect the battery ground wire (negative terminal)." For Hongqi models equipped with CAN bus systems, a 5-minute wait is necessary to ensure complete discharge of capacitors.
Industry Standard: QC/T 413-2002 Basic Technical Conditions for Automotive Electrical Equipment specifies that electrical maintenance must follow the principle of "disconnecting the negative terminal first and waiting for complete circuit discharge" to prevent electric shock and short-circuit risks.
Nissan Standard: The Nissan Teana Service Manual designates the starter mounting bolt specifications as M8/M10, compatible with 10mm/12mm sockets.
Hongqi Standard: The Hongqi H5 Service Manual specifies that the starter mounting bolts are M8, requiring an 8mm socket for removal/installation.
