The following is the general installation method for Chery's 12V starter motor: •  Preparation work: Confirm that the starter motor model matches the vehicle. Prepare common tools such as wrenches, screwdrivers, and sockets. Park the vehicle on a flat and safe surface, turn off the engine, and disconnect the negative cable of the battery to prevent dangers such as electric shock or short circuit during the installation process.  •  Locate the installation position: The starter motor is usually located at the junction of the engine and the transmission, near the flywheel housing. It may be necessary to access the bottom of the vehicle or look inside the engine compartment; the specific position varies slightly depending on the vehicle model.Clean the installation position: Use a cleaning cloth or a special cleaning agent to clean the installation position of the starter, remove impurities such as dust, oil stains, and rust, and ensure that the installation surface is clean and flat so that the new starter can be installed stably.  •  Install the starter: Align the new starter with the installation holes, put it in slowly, and ensure that the gears of the starter are correctly meshed with the flywheel ring gear. Then, screw the fixing bolts into the corresponding screw holes, but do not tighten them.Tighten the fixing bolts: Use a torque wrench to tighten the starter's fixing bolts according to the specified torque value. Generally speaking, the tightening torque for the starter fixing bolts of Chery models may be around several tens of Newton-meters, and the specific value should refer to the maintenance manual of the corresponding model. When tightening, follow the diagonal or cross-tightening sequence to ensure that the starter is evenly stressed.Connecting electrical circuits: Firmly connect the electrical connecting wires of the starter to the starter in accordance with the marks made during disassembly or the correct connection method. Ensure that the connectors are tightly connected without looseness to prevent poor contact from affecting the normal operation of the starter.  •  Reconnecting the negative battery cable: After checking that the installation of the starter and the circuit connections are correct, reconnect the negative battery cable to the battery and ensure it is firmly connected.Testing the starter motor: Enter the cockpit, turn the ignition key to start the vehicle, and observe whether the starter motor can operate normally to drive the engine to start. At the same time, pay attention to any abnormal noises from the starter motor and feel whether the starting process is smooth. If the starter motor works normally, it indicates that the installation is successful; if there is an abnormality, timely troubleshooting should be carried out, such as checking the line connections and the tightness of the bolts.

When installing the Chery 12V starter motor, the following precautions should be noted:Before installationConfirm model matching: Carefully check whether the model of the starter motor matches the vehicle's requirements to avoid failure to install or use it normally due to mismatched models.Check component condition: Inspect the starter motor for external damage, such as cracked casing, loose terminals, etc.; at the same time, check whether the starter motor's gears are worn or have missing teeth. If there are any problems, replace them in a timely manner.Disconnect the vehicle power supply: Be sure to turn off the ignition switch first, then disconnect the negative cable of the battery to prevent dangers such as short circuits or electric shocks during the installation process, especially for vehicles with computer-controlled engines.Clean the installation location: Use a clean cloth or special cleaning agent to clean the installation location of the starter motor, removing impurities such as dust, oil stains, and rust to ensure the installation surface is clean and flat.During installation •  Avoid damaging components: For components with a tight fit, never use brute force such as hammering or knocking. Instead, use pulling and pressing tools for separation and installation to prevent damage to the components.  •  Ensure secure installation: Align the starter with the mounting holes and insert it slowly. Make sure the starter's gear properly meshes with the flywheel ring gear, then screw in the fixing bolts. Use a torque wrench to tighten the bolts according to the specified torque value and in a diagonal or cross-tightening sequence. Excessive torque may cause component deformation, while insufficient torque may lead to the starter becoming loose, affecting its normal operation.Correctly connect the wires: When connecting the electrical wires of the starter, ensure that the connectors are tightly connected without looseness, and pay attention to the connection sequence. Usually, during installation, you should first connect the positive battery cable on the solenoid switch, then connect the positive and negative battery cables. Moreover, before connecting the positive and negative battery cables, make sure the ignition switch is in the off state. At the same time, remember the positions and connection methods of each wire to avoid wrong connections.After installation •  Check tools and components: After the installation is completed, carefully check whether all tools have been taken out, and at the same time check whether there are any missing parts or debris around the starter.  •  Test the starter: After reconnecting the negative cable of the battery, enter the cockpit, turn the ignition key to start the vehicle, observe whether the starter can operate normally to drive the engine to start, listen for any abnormal noises from the starter, and feel whether the starting process is smooth. If the starter works abnormally, troubleshoot the problem in a timely manner, such as checking whether the line connections are correct and secure, and whether the bolts are tightened.

References：My content regarding the installation precautions for the Chery 12V starter is mainly referenced from platforms such as Autohome and PCauto. The details are as follows:Autohome: Multiple Q&A and articles on Autohome mention that before installing the starter, the negative pole of the battery should be disconnected to prevent short circuits, the ignition switch should be turned off, and the key should be pulled out. During the installation process, it is strictly prohibited to hit the starter with a hammer or wrench to avoid damaging parts. When tightening screws or nuts, it should be done evenly and symmetrically to prevent part deformation. After installation, check whether all tools have been taken out. These contents have provided me with practical operational experience. Relevant links include https://www.autohome.com.cn/ask/14010888.html, https://www.autohome.com.cn/

Pacific Auto Network: According to the information from Pacific Auto Network, when installing a starter motor, you should first connect the positive battery cable on the solenoid switch, then connect the positive and negative battery cables. Moreover, before connecting the positive and negative battery cables, ensure that the ignition switch is in the off state to protect the electronic devices on the vehicle. After the installation is completed, test the working condition of the starter motor: turn the key and listen to see if the starter motor can operate normally and if there are any abnormal noises. Its comprehensive introduction to the installation process and key points for attention is an important reference for me to sort out the precautions.
