The installation process of the 12V 1.7KW starter is generally similar across most Nissan and Mitsubishi models, with the core steps focusing on power-off protection, positioning and fixation, circuit connection, and test verification. However, there are minor differences due to variations in chassis or engine layouts among some models. Below is a universal installation method suitable for most mainstream models, along with model-specific key points:
Park the vehicle in a flat and solid area, ensure the engine is completely turned off and cooled down. Disconnect the negative cable of the car battery to prevent short circuits during installation, which could damage the starter or the vehicle’s electrical components.
Prepare tools such as a socket wrench, torque wrench, and pliers. If bolts are rusted, prepare penetrating solvent to assist in operation. Verify the parameters of the new starter to confirm it is a compatible 12V 1.7KW model. Meanwhile, prepare a small amount of calcium-based grease for lubricating the spiral spline part, and remove the shipping protective parts from the new starter.
The starter is usually located at the junction of the engine and transmission. For some models (e.g., Mitsubishi Montero) equipped with an engine splash guard or starter access cover, remove these components first. Afterwards, clean dust and oil stains from the installation base and its surrounding area, and use sandpaper to polish rust from the bolt holes to avoid affecting installation stability.
Place the 12V 1.7KW starter stably into the installation base, adjust the angle to align its fixing holes accurately with the vehicle’s mounting holes. Use a socket wrench to initially tighten the fixing bolts, then use a torque wrench to fasten them to the torque specified in the vehicle’s maintenance standards (generally controlled at approximately 20–25 ft-lb). This prevents bolt loosening, which could cause vibration or abnormal noise during operation.
According to the marks made during disassembly, reconnect the starter’s power cable, solenoid switch plug, and other connectors to their corresponding interfaces. Ensure the plugs are fully engaged and the terminals are not loose during connection. For models such as the Nissan Bluebird, special attention must be paid to fastening the cable connectors to prevent poor contact from affecting the transmission of the starting signal.
Evenly apply calcium-based grease to the spiral spline part of the starter; a moderate amount of grease can also be applied to the contact area between the shift fork and the drive gear to reduce friction and wear during operation. At the same time, check the distance between the end face of the drive gear and the end face of the flywheel ring gear—it should be maintained at 2.5–5mm. If it does not meet the requirement, adjust it by adding or removing gaskets.
If the engine splash guard, access cover, or other components were removed earlier, reinstall and fasten them one by one in the reverse order of disassembly to prevent loose components from falling off while driving.
Reconnect the negative terminal of the battery, turn the vehicle key to start the engine, and observe whether the starter can smoothly drive the engine to run without abnormal noise.
Release the starter switch immediately after starting to avoid idle wear of the starter. If the engine fails to start on the first attempt, wait for 1–2 minutes before trying again, and the single start time should not exceed 5 seconds. In addition, professional equipment can be used to check the current and voltage output of the starter to ensure it meets the operating standards of the 12V 1.7KW specification, with no issues such as unstable power supply.
Based on the structural characteristics and installation commonalities of the 12V 1.7KW starters for Nissan and Mitsubishi vehicles, the installation precautions can be categorized into four key dimensions: safety operations, component compatibility & assembly, circuit connection, and testing & usage. The details are as follows:
Before installation, be sure to turn the ignition switch to the LOCK position and disconnect the negative terminal of the battery. For some Nissan models involving control unit operations, it is also necessary to disconnect both positive and negative cables. After power disconnection, wait for at least 3 minutes to allow the vehicle’s capacitors to discharge completely—this avoids short circuits during operation that could damage the starter, ECU, or other components. During installation, never use pneumatic or electric tools near airbag sensors when the ignition switch is on, as vibration may trigger airbag deployment.
The area around the starter is filled with precision electrical components and pipelines. Operate gently during installation to prevent collisions with the starter housing, as well as wire harnesses, oil pipes, and other parts in the engine compartment. Additionally, wait for the engine to cool down completely before operation to avoid burns from high-temperature components. Check that the insulation layer of tools is intact before use.
Confirm that the new starter is a compatible 12V 1.7KW model. For Mitsubishi vehicles equipped with the M001T68381 starter, this specific specification must be strictly matched. Before installation, inspect the starter for no external damage, and ensure internal components such as brushes and commutators are in normal condition. Remove the shipping protective parts from the new starter.
When fixing the starter, use the cross-tightening method to install bolts to avoid deviation of the mounting surface. For some Mitsubishi models, the torque of certain fixing bolts must be controlled within the range of 4.4–12.7N·m; for Nissan models, the bolt tightening torque shall generally follow the specifications in the maintenance manual. Excessive torque may damage threads or the housing, while insufficient torque will cause vibration and abnormal noise during operation.
Before applying grease, remove old grease to prevent mixing of different types of grease (which may affect performance). For Mitsubishi models, Multemp PS2 grease is recommended—apply it to the gear shaft splines, overrunning clutch sliding parts, etc. Note that conductive parts such as the starter mounting surface and brushes must be kept free of grease. For Nissan models, calcium-based grease can be applied to the spiral splines, with focus on lubricating the contact area between the shift fork and the drive gear.

The precautions for installing the 12V 1.7KW starter in Nissan and Mitsubishi vehicles you referred to do not come from a single authoritative original text. Instead, they are summarized by integrating information from official maintenance manuals for Nissan and Mitsubishi models, as well as professional Q&A content on automotive vertical platforms. The specific source basis is as follows:
For Nissan models: The original factory maintenance manual of Dongfeng Nissan New Teana includes safety specifications for starter installation. For example, it mentions that before disassembling and installing the control unit, the ignition switch must be turned to the LOCK position, both positive and negative battery cables should be disconnected, and a wait of at least 3 minutes is required to prevent accidental airbag deployment. This serves as an important basis for the key points related to standardized power disconnection in the "Safety Operations" category of the summary.
For Mitsubishi models: Mitsubishi’s engine maintenance manuals (such as the manual corresponding to the 4M41 engine) contain basic operation specifications for starter disassembly, installation, and fastening. Its requirements for component installation accuracy and bolt tightening provide support for the precautions related to component assembly in the summary.
The Q&A related to starter replacement on Autohome (a major Chinese automotive platform) mentions that the starter motor should not be energized for more than 5 seconds each time, and an interval is required between consecutive starts. It also emphasizes that bolts must be tightened to the specified torque during installation. This content has been integrated into the "Testing & Usage" and "Component Compatibility & Assembly" categories of the precautions.
The Q&A related to starter maintenance on Pacific Auto (another key Chinese automotive platform) covers content such as the recommended tightening torque of terminal nuts (controlled at 14.7–17.7N·m) and the requirement to use the cross-tightening method for installing fixing screws. These points are also reflected in the key points related to circuit connection and component assembly in the summary.
