The installation process of the Great Wall 12V 1.1KW starter can refer to the general operating specifications of mainstream Great Wall models such as Haval H5 and Wingle 7, while complying with the operational requirements based on the characteristics of this specific starter. The detailed steps are as follows. Ensure safety protection and component protection during operation:
Prepare tools including an 8-17mm socket wrench, box-end wrench, Phillips screwdriver, and torque wrench. Meanwhile, prepare compatible accessories such as a 12V 1.1KW starter assembly, new gaskets, and insulating tape. Additionally, it is recommended to equip a multimeter, gloves, and goggles for subsequent testing and safety protection.
Park the vehicle on a flat and solid surface, turn off the engine, and pull the handbrake. Open the hood and must disconnect the negative battery cable to eliminate short circuits or electric shock hazards during installation. If the starter is hidden in some models, use a jack to lift the front of the vehicle and secure it with safety stands to ensure operational safety.
Wipe the starter mounting surface on the engine with a clean cloth to remove oil, dust, and residual impurities. Thoroughly clean any remaining old gaskets to ensure the new starter fits tightly against the mounting surface.
Align the new 12V 1.1KW starter with the mounting bracket on the engine. Adjust the angle so that the starter's drive gear faces the flywheel ring gear, ensuring the starter's mounting holes are accurately aligned with the bracket holes. Slowly fit the starter onto the mounting surface to avoid colliding with surrounding pipelines, intake manifold, or other components.
Insert the fixing bolts and manually screw them in 2-3 turns for initial fixation to prevent thread stripping. Then use a torque wrench to tighten all bolts in stages and symmetrically with a torque of approximately 37N·m. This ensures the starter is securely installed and prevents vibration during operation.
First, locate the power terminal on the starter. Connect the power cable from the positive battery terminal and tighten the large terminal nut, controlling the torque to approximately 9.8N·m.
Align the control wire interface and tighten the fixing nut on the control wire to ensure a secure connection. Insulating tape can be used for auxiliary reinforcement to prevent poor contact and sparking.
For models equipped with an intake manifold heat shield, reattach and tighten the shield's fixing bolts after wiring is completed.
If a jack and safety stands were used, slowly lower the vehicle and remove the stands and jack. Reconnect and tighten the negative battery cable, then confirm all components and wiring are in normal condition.
Turn on the ignition switch and attempt to start the vehicle. Observe if the starter operates smoothly without abnormal noise and if the engine starts successfully. After startup, use a multimeter to test the starter's operating voltage and current to ensure they are within the normal range. If issues such as weak starting or abnormal gear meshing noise occur, stop the engine and inspect the bolt tightness and wiring connections.
Wear insulating gloves and safety goggles throughout the operation to avoid electric shock when hands touch circuit terminals, scratches from metal components, or oil splashing into eyes. Do not wear metal accessories such as rings or bracelets during work to prevent accidental conduction.
Must disconnect the negative battery cable before installation (removal order: negative first, then positive; connection order: positive first, then negative). Live operation is strictly prohibited. After disconnection, wait 5-10 minutes to release residual electricity in the vehicle circuit, avoiding sparks caused by short circuits and damage to electrical components.
Vehicle support requirements: If the vehicle needs to be lifted, use a compliant jack with safety stands for fixation. Never work relying solely on a jack. When operating under the vehicle, ensure the ground is flat and solid; avoid operations on soft ground or slopes.
Keep the operating area well-ventilated and dry, and away from flammable and explosive materials (such as gasoline, diesel, alcohol, rags, etc.) to prevent fires caused by short-circuit sparks. Clear debris inside the hood to avoid accidents from falling tools or parts.
The starter weighs approximately 3-5kg. Lift it stably during installation to prevent slipping and damaging engine components or the operator’s feet. Push and place gently when aligning; violent impact on the mounting surface or surrounding parts is prohibited.
Confirm that the model, voltage (12V), and power (1.1KW) of the new starter match the original Great Wall specifications. Focus on verifying the mounting hole spacing, drive gear module, and number of teeth—they must fully match the flywheel ring gear to avoid abnormal meshing. It is recommended to choose original Great Wall accessories or compliant brand products; non-standard products are strictly prohibited.
Inspect the starter’s appearance: The housing should be free of cracks and deformation. The drive gear should move flexibly (can rebound smoothly when pressed manually) without jamming, rust, or tooth wear. Terminals should be free of oxidation and looseness, solenoid switch terminals should be intact, and wires should have no damage or aging.
Verify installation accessories: The specifications of fixing bolts must match the original factory (usually M10 high-tensile bolts). Never use bolts with mismatched specifications, fatigue, or rust. New gaskets should match the size of the mounting surface; replacing with new gaskets is recommended to ensure tight sealing and prevent loosening due to vibration.
Check the line status: The positive and negative battery wires should have no damage, the insulation layer should not be aged, and the terminals should be free of oxidation. If there is wire damage, repair or replace the wires first before installation.
When aligning the starter, manually rotate the flywheel (with the ignition switch disconnected) to ensure precise meshing between the flywheel ring gear and the starter's drive gear before fitting the starter to the mounting surface. This avoids tooth surface damage caused by hard collision. The mounting surface must be thoroughly cleaned, free of oil, rust, or residual old gaskets—otherwise, it will result in poor fit, leading to vibration and bolt loosening during operation.
First, manually screw the fixing bolts 2-3 turns to confirm no thread misalignment. Then, using a torque wrench, tighten them strictly according to the torque standard of 37N·m following the principle of "diagonal symmetry and step-by-step tightening". Over-torque tightening (prone to thread stripping and mounting surface deformation) or insufficient tightening (causing vibration and abnormal noise during operation) is prohibited.
Torque control for terminal nuts:
The large nut of the power terminal: 9.8N·m
The fixing nut of the control wire: 8-10N·m
Avoid over-tightening (which may damage wires or terminals) or under-tightening (leading to poor contact and sparking).

The precautions previously provided for the installation of the Great Wall 12V 1.1KW starter are explicitly cited from two sources. Detailed information and their correlation with the precautions are as follows:
This manual is a professional maintenance guide formulated for mainstream Great Wall models equipped with the 12V 1.1KW starter, such as the Haval H5 and Wingle 7. Many details in the precautions are derived from this manual, including:
The tightening torque of 37N·m for the starter fixing bolts;
The tightening standard of 9.8N·m for the power terminal nut;
Model-specific operational specifications such as starter alignment and avoidance of surrounding components.
These contents are fully consistent with the engine compartment structure and starter installation characteristics of the two models.
This is a universal technical specification in the field of automotive starters. The precautions are based on this standard for the following key points:
Detection standards for starter operating parameters (e.g., operating voltage of 10.5-12.5V);
Requirements to prevent starter overheating, such as limiting a single startup duration to no more than 5 seconds;
Tightening principles for threaded fasteners;
Inspection requirements for starter appearance and performance.
For example, the provisions on the short-time duty system of starters in the standard correspond to the precaution of controlling startup duration during post-installation testing to avoid component burnout.
