| Voltage | 12 Volts |
|---|---|
| Wattage | 1.4 KW |
| Amperage | 60 Amps |
| Number of Teeth | 10 |
| Rotation | Clockwise |
This A-Premium starter is a direct-replacement style unit built to fit 3.5L rear-wheel-drive Infiniti G35, M35, FX35 and Nissan 350Z models without a nose cone. It provides the basic functions of a starter motor: engage the flywheel, spin the engine to start, and then disengage reliably. Installation is straightforward for a DIYer or shop because it matches the factory mounting, electrical connections, and rotation direction.

Choosing the Right Infiniti G35 Starter Motor: Key Factors to Consider
Fitment and Mounting
Starter motors must match the G35's bell housing pattern, bolt spacing, and flange orientation to install without modification. Proper fitment prevents alignment issues that can cause premature wear on the starter drive and flywheel ring gear.
Verify that the replacement lists the Infiniti G35 specifically and includes any required mounting hardware or adapter plates. A correct mechanical interface reduces installation time and avoids the need for custom machining or adjustments that can introduce failure points.
Electrical Output and Torque
The starter's electrical characteristics, including rated torque and current draw, determine how quickly and reliably the engine will crank. Higher torque is beneficial for cold starts or higher-compression engines, while appropriate current draw ensures the vehicle's electrical system can supply the starter without excessive voltage drop.
Look for specification sheets showing torque ratings or amp draw under load. Matching the starter's electrical profile to the G35's charging system and battery capacity helps ensure consistent starting performance and reduces stress on wiring and connectors.
Solenoid and Drive Mechanism
The solenoid controls engagement between the starter drive and the flywheel. Reliable solenoid action prevents partial engagements that cause grinding or repeated starting attempts. Similarly, the starter drive mechanism should provide smooth, positive engagement and retraction to protect the flywheel teeth.
Inspect whether the replacement includes a robust solenoid design and a quality drive assembly. Rebuildable or replaceable solenoids and drives can make future repairs simpler and extend the overall life of the starter.
Durability and Materials
Starters operate in harsh environments with heat, vibration, and exposure to contaminants. Corrosion-resistant housings, sealed electrical connections, and quality internal components like bearings and brushes all contribute to longevity.
Prioritize units with reinforced housings and protection against moisture and road grime. Durable construction reduces the likelihood of premature failures and decreases the need for repeated replacements over the vehicle's service life.
Ease of Installation and Serviceability
Some starter motors are designed for straightforward bolt-in installation, while others may require partial disassembly of nearby components. Ease of installation affects labor time and the likelihood of installation errors that can cause future problems.
Choose starters that offer clear installation guidance, included hardware, and accessible serviceable parts. Units that allow replacement of common wear items like brushes or solenoids without removing the entire starter can save time and expense during maintenance.
Warranty and Support Documentation
A clear warranty and access to technical documentation indicate manufacturer confidence and make resolving issues easier. Warranties cover defects in materials and workmanship, giving protection against early failures.
Look for documented warranty terms and available installation or troubleshooting guides. Good technical support can help with questions on fitment, wiring, or testing procedures, reducing installation uncertainty and downtime.
How We Chose the Best Infiniti G35 Starter Motor
We focused on starter motors that match Infiniti G35 factory fitment and mounting points, ensuring direct replacement without modification. Electrical performance was assessed by looking at rated torque or amp draw where available, plus compatibility with the vehicle's 12-volt system to ensure reliable cranking and engagement. Durability and materials were prioritized, with attention to heavy-duty components such as reinforced housings, quality bearings, and corrosion-resistant finishes. We also considered solenoid reliability and overall mechanical design since these affect longevity and consistent operation under repeated starts. Ease of installation and availability of common replacement parts like solenoids and drive assemblies were included as practical selection criteria.Units were excluded if they required major modifications, lacked clear fitment information for the Infiniti G35, or did not provide basic electrical or mechanical specifications. We also excluded designs with known widespread fitment ambiguity or insufficient documentation on compatibility and mounting.
Our full evaluation process is outlined in our review methodology.
FAQ
What are common starter motor symptoms on an Infiniti G35?
Common symptoms often include slow or labored cranking, a single click or rapid clicking when you turn the key, or no response at all. You may also notice intermittent starting or grinding noises if the starter drive is not engaging properly. These signs usually point to electrical issues, a failing solenoid, or mechanical wear in the starter assembly.
How do I test a starter on an Infiniti G35?
Basic tests usually start with checking battery voltage and connections to ensure adequate power. A bench test or voltage drop test while cranking can indicate whether the starter is drawing excessive current or not engaging. Because several components can cause similar symptoms, combine electrical checks with a physical inspection of mounting, wiring, and the starter drive.
Can starter solenoid problems cause a clicking noise?
Yes, a weak or failing solenoid often produces a single click or repeated clicking when you try to start the car. Clicking may mean the solenoid is unable to fully actuate the starter drive or that the starter is not receiving enough current due to poor battery or connection issues. It is important to diagnose both the solenoid and the electrical supply before replacing parts.
Are starter motor replacement parts commonly available for the Infiniti G35?
Many of the common wear items such as solenoids, brushes, and drive assemblies are available as replacement parts for the G35's starters. Availability can vary by design and manufacturer, but choosing a unit with documented serviceability makes sourcing parts and future repairs easier. Confirm part numbers and compatibility before purchasing components.
Is starter motor installation difficult on an Infiniti G35?
Installation difficulty depends on the starter's design and the vehicle's layout, but many replacements are designed for direct bolt-in installation. Typical tasks include disconnecting the battery, removing electrical connections, and unbolting the starter from the bell housing. Some situations may require lifting the vehicle or removing nearby components to gain access.
Conclusion
When choosing a starter motor for an Infiniti G35, prioritize correct mechanical fitment and matching electrical output first. Those dimensions determine whether the unit will install cleanly and deliver reliable cranking performance with the vehicle's existing battery and wiring.Balance durability, solenoid quality, and ease of installation against serviceability and warranty coverage. Paying attention to these tradeoffs helps you select a starter that minimizes installation headaches and reduces the likelihood of repeat failures.
