The installation procedures for 12V 1.4KW starters of Chery and Great Wall vehicles are basically the same. The core steps include power-off protection, precise alignment and fixation, and standardized circuit connection. Only the specific installation positions of the starter and the number of fixing bolts vary slightly among different models. The following is the general installation method. Before operation, it is recommended to refine the steps in accordance with the maintenance manual of the corresponding vehicle model.
First, check the model of the new starter to confirm that it is a 12V 1.4KW specification suitable for the corresponding Chery or Great Wall vehicle model, and inspect the starter for no external damage and complete components.
Prepare tools such as 10-12mm box-end wrenches, sockets, torque wrenches, Phillips screwdrivers, etc. Meanwhile, turn off the vehicle engine and park it on a flat ground, then disconnect the negative cable of the storage battery to avoid short circuit or accidental startup during operation.
The starters of Chery and Great Wall vehicles are mostly located at the junction of the engine and the transmission. After removing the old starter, use a cleaning agent or alcohol to remove oil stains, rust, and dust from the mounting surface. If there are severely rusted mounting holes, they can be lightly polished to ensure a flat mounting surface and prevent any impact on the fixing stability of the starter.
Accurately place the new starter into the installation position, align it with the reserved mounting holes, and insert the fixing bolts.
Tighten the bolts to the specified torque with a torque wrench; the recommended torque for the bolts is generally around 37N·m. Avoid over-tightening, which may damage the threads, or under-tightening, which may cause vibration during startup.
Some Chery and Great Wall vehicle models adopt double-bolt fixation, so the bolts should be tightened gradually in a diagonal sequence to ensure that the starter is closely attached to the mounting surface.
First, connect the power cable (thick wire) of the starter, which usually corresponds to the terminal marked "30", with the tightening torque of the nut being approximately 9.8N·m.
Then connect the control cable (thin wire, mostly the terminal of the electromagnetic switch), insert it firmly into the plug interface, and avoid reversing the circuit connection.
If the vehicle model is equipped with a wire harness bracket, fix it with bolts at the same time with a torque of about 8.4N·m, and install wire harness clips to organize the circuits and prevent shaking and friction.
Reconnect the negative cable of the storage battery and close the terminal cover.
Then turn the vehicle key to test, observe whether the starter can run normally, check for any abnormal noise, and see if the engine can be smoothly cranked to start.
If problems such as weak startup or no response occur, check whether the circuit connections are loose or the starter installation is offset. After troubleshooting and confirming no issues, perform the test again.
In addition to the routine operation requirements, the following precautions shall be focused on during the installation of 12V 1.4KW starters for Chery and Great Wall vehicles to ensure installation safety and equipment reliability:
The negative cable of the storage battery must be disconnected before installation, and it is strictly prohibited to reconnect the power supply until all mechanical and electrical connections are completed. If temporary power-on testing is required during the operation, ensure that the starter is not meshed with the engine flywheel to prevent mechanical damage or personal injury caused by accidental startup.
Before installation, thoroughly remove oil stains, rust, and carbon deposits from the engine-side mounting surface; lightly polish it with fine sandpaper if necessary. The mounting flange of the starter must be fully fitted to the engine surface without any gaps. Otherwise, it will lead to uneven stress on the bolts, vibration and abnormal noise during startup, and even damage to the threaded holes.
Tighten the fixing bolts gradually in a diagonal sequence, with the torque strictly controlled within the range of 35–40N·m. Over-tightening (which may cause housing cracking) or under-tightening (which may lead to loosening and displacement during startup) is not allowed.
If the bolts are stripped or deformed, replace them with high-strength bolts of the same specification immediately. The use of ordinary bolts as substitutes is prohibited.
The power cable (thick wire) shall be connected to the "30" terminal of the starter, and the control cable (thin wire) shall be connected to the "50" terminal. Reversing the positive and negative connections is strictly prohibited, otherwise it will burn out the electromagnetic switch or internal windings.
The tightening torque of the wiring nuts shall be controlled within 8–10N·m. After connection, wrap the exposed terminals with insulating tape to prevent short circuits caused by friction between the shaking wire harness and engine components.
The wire harness shall be fixed with original factory clips, and kept away from high-temperature components such as exhaust pipes to prevent aging and cracking of the wires.
When meshing the starter with the flywheel ring gear, if alignment is difficult, rotate the crankshaft to adjust the flywheel position. It is strictly prohibited to strike the starter housing or gears to prevent deformation of the overrunning clutch and armature shaft.
During installation, check whether the travel of the shift fork is normal to ensure that the overrunning clutch can be smoothly pushed out for meshing when powered on and fully reset when powered off.
If precision components such as the armature and stator windings are contaminated with oil stains, wipe them only with gasoline-dampened cotton yarn; do not wash them with water or rinse them directly with high-pressure cleaning agents to prevent damage to the insulating layer.
After installation, check whether the dust cover is intact to prevent sediment and oil stains from entering the starter interior, which may cause bearing wear or winding short circuits.
During the initial power-on test, turn the key briefly (single power-on duration shall not exceed 3 seconds), and observe the operation status of the starter: no abnormal noise, no jamming, and the engine can be cranked to start smoothly.
If idling occurs without meshing with the engine, it is mostly due to improper adjustment of the shift fork or a fault in the overrunning clutch. If jamming occurs after meshing, check whether the ring gear has broken teeth or whether the installation angle of the starter is offset.
If a burnt smell is detected or smoke is observed during the test, cut off the power supply immediately, troubleshoot the circuit connections or internal faults of the starter, and repeated testing is prohibited.
The installed starter must be fully consistent with the original factory specifications of the vehicle model (12V 1.4KW). Mixing and matching starters with different power or voltage ratings is prohibited, otherwise it will lead to abnormal starting current, storage battery power depletion, or weak engine startup.

The installation precautions for 12V 1.4KW starters of Chery and Great Wall vehicles mentioned earlier are compiled based on the general installation specifications for automotive starters and the installation characteristics of starters for corresponding Chery and Great Wall vehicle models. Their core basis comes from the following types of publicly available automotive maintenance knowledge sources:
Materials such as the starter replacement process for the 2009 Chery Tiggo 3 recorded in the Pacific Auto Encyclopedia, and the installation precautions for the Great Wall C50 starter detailed on the Auto Master platform, explicitly specify key points including the power-off operation sequence, prohibition of violent disassembly and assembly, and component cleaning methods. These contents serve as the fundamental basis for formulating starter installation guidelines suitable for the two vehicle brands. For example, the requirement to disconnect the battery ground cable first during the disassembly and assembly of the Chery Tiggo 3, and the stipulation to select a matching starter model during the installation of the Great Wall C50, have both been incorporated into the compiled installation precautions.
Knowledge about the general installation and replacement of starters published on platforms such as Pacific Auto and Autohome defines torque standards for starter installation (e.g., 37N·m for fixing bolts and 9.8N·m for terminal nuts) and cleaning taboos for components such as the armature. These universal specifications are applicable to 12V starters for most vehicle models including Chery and Great Wall, and act as an important reference for the torque requirements and component protection measures specified in the precautions.
