The installation position and details of the starter motor vary slightly among different Lamborghini models. Taking popular models such as the Aventador LP700 as examples, their 12V starter motors are mostly located at the rear of the engine. Due to the compact layout of the engine compartment, partial disassembly of surrounding components is required before installation. Below is a detailed installation method combined with the characteristics of supercar maintenance:
Prepare a torque wrench, 10-19mm socket set, insulating gloves, a jack with stands, undercarriage shield removal tools, a brand-new original 12V starter motor (e.g., model 7M911024A compatible with LP700), original-specification mounting bolts, terminal protection sleeves, insulating tape, and special coolant.
Park the vehicle on a level surface, apply the handbrake, and secure the wheels with wheel chocks.
Open the front trunk to remove the luggage compartment, disconnect the vehicle's main battery cable, and wait 5-10 minutes to discharge residual electricity.
Lift the vehicle with a jack and firmly support it with stands. Remove the undercarriage lower shield and bottom plate fixing crossbar.
If the starter motor is blocked by coolant hoses, disconnect the hoses, drain the coolant, and mark the pipelines to avoid misinstallation.
Find the starter motor mounting position at the rear of the engine. Clean oil stains and rust from the mounting seat surface to ensure a flat mating surface.
Align the new starter motor with the mounting holes, manually screw in 2-3 mounting bolts (do not fully tighten), and gently rotate the flywheel for auxiliary calibration to ensure precise alignment between the starter gear and the ring gear of the flexplate.
Gradually tighten the mounting bolts in a diagonal sequence using a torque wrench. Referring to the installation standards for similar supercar components, the recommended torque is approximately 37N・m. Avoid over-tightening (which may cause cracking of the mounting seat) or under-tightening (which may lead to vibration).
If the starter motor is equipped with a heat shield, install it on the side close to the exhaust manifold and catalytic converter for heat insulation protection.
First, connect the high-power cable of the starter motor to the copper terminal block, then connect the relay power supply feeder on the solenoid valve. When fixing terminal 30 with a nut, control the torque at 9.8N・m.
After completing all wiring, install terminal protection sleeves and reinforce with insulating tape to prevent interference between wires and rotating engine components.
Subsequently, install the wiring harness bracket with bolts (torque: 8.4N・m) and secure 2 wiring harness clips.
Reinstall the engine bracket and motor mounts in the reverse order of disassembly. Replace the original water hoses with new seals before reinstalling to prevent coolant leakage.
Fill the cooling system with original special coolant.
Reconnect the vehicle's main battery cable and close the terminal cover. Start the vehicle to allow coolant to circulate through the pipelines, then lift the vehicle again to check for coolant leakage from the undercarriage.
Test the starting performance by turning the ignition switch multiple times. Observe whether the starter motor operates smoothly without abnormal noise, and ensure the starter motor disengages immediately after the engine starts.
Use a diagnostic computer to clear fault codes, increase the vehicle speed to bring the engine to operating temperature, and recheck the starter motor wiring for overheating or looseness. After confirming no abnormalities, reinstall the undercarriage shield.
Given the compact engine layout of Lamborghini models (with the Aventador LP700 as a typical example), the characteristics of precision components in supercars, and the special processes required for starter installation, the following are more detailed precautions covering the entire process from preparation and operation to inspection and subsequent maintenance. These are designed to ensure installation safety and stable operation of the components, in addition to the key points mentioned earlier:
The starter must be an original equipment manufacturer (OEM) model tailored to the specific vehicle, such as model 7M911024A for the LP700 . Its material and performance are engineered to match the operating conditions of the supercar’s high-performance engine. The use of starters designed for regular vehicles is strictly prohibited, as this may easily lead to gear meshing failures or circuit burnout.
Small spare parts like mounting bolts and water pipe seals must comply with OEM specifications. Supercar engines generate intense vibrations, and non-OEM parts are prone to breakage and leakage. Professional torque wrenches with high precision should be used to avoid component damage caused by torque deviations.
Before disconnecting the coolant hoses, clearly mark each pipeline. The engine compartment of a Lamborghini is packed with intricate pipelines, and incorrect reinstallation can result in cooling system malfunctions. When draining the coolant, use a dedicated container for collection to prevent contamination and facilitate subsequent inspections of the coolant condition.
Components such as the removed engine brackets and motor mounts should be placed in the order they were disassembled and reinstalled in the reverse sequence . Meanwhile, check if the motor mounts are aged. If cracks are found, replace them promptly to prevent engine vibrations from transferring to the starter and shortening its service life.
When reinstalling the wiring harness, secure the wiring harness clips firmly. Ensure the wiring is kept away from high-temperature components like the exhaust manifold and catalytic converter, and does not come into contact with moving parts such as belts and gears. This prevents wire wear or melting.

The supplementary precautions regarding the installation of the 12V starter for Lamborghini are not derived from a single official original document or publicly available authoritative literature. Instead, they are compiled and organized based on supercar maintenance industry practices, maintenance cases of relevant Lamborghini models, and general automotive starter installation specifications. Its core information sources can be categorized into the following types:
The details in the content, such as the installation position of the starter in the Aventador LP700 and the need to disassemble the coolant hoses and undercarriage shield, are highly consistent with the practical replacement cases of the Lamborghini LP700 starter motor posted on platforms like Douyin. These cases are derived from the actual operation records of supercar repair shops and serve as crucial references for the detailed installation procedures of starters for such models. Practical key points, including the requirement to use an OEM - specified starter and properly mark pipelines during installation, are all summarized from the experience accumulated in these maintenance scenarios.
Content such as disconnecting the main battery cable to discharge residual electricity, tightening bolts in a diagonal sequence with torque control, and reinforcing insulation protection after wiring is consistent with the general assembly and disassembly precautions for automotive starters published on platforms like Autohome and PCauto. These general specifications form the basic guidelines in the automotive maintenance field and are applicable to various vehicle models including Lamborghini, providing a fundamental operational framework for the installation of supercar starters.
As a supercar, Lamborghini features a compact engine compartment layout, a sophisticated electrical system, and extremely high requirements for component compatibility. Key points emphasized in the content, such as "using OEM parts throughout the process", "prohibiting brute force striking", and "clearing fault codes with a diagnostic computer", are deduced based on the maintenance characteristics of precision supercar machinery. Although compatibility is also valued during the installation of starters for ordinary family cars, the high-performance operating conditions of supercars impose more stringent requirements on part specifications and operational accuracy. Such content represents targeted adjustments to general maintenance specifications, tailored to the unique characteristics of supercars.
