Infiniti G37 Workshop Manuals and Repair Manuals

To check the battery in your Infiniti G37, start with ensuring the engine and all electrical accessories are turned off. Open the hood and locate the battery. Check for any visible signs of corrosion or loose connections on the battery terminals. Using a multimeter, set it to the DC voltage mode and connect the positive (red) lead to the positive terminal and the negative (black) lead to the negative terminal. A fully charged battery should read around 12.6 volts or higher. If the reading is significantly lower, it may indicate a weak or discharged battery that may need to be recharged or replaced.

To check the tire pressure in your Infiniti G37, first, ensure the tires are cold. Remove the valve cap from each tire and use a tire pressure gauge to measure the pressure. Compare the reading to the recommended tire pressure specified in the owner's manual or on the driver's side door jamb. Adjust the pressure as needed using an air compressor or let out excess air if necessary. Proper tire pressure promotes safety, improves handling, and helps maximize tire life.

To jump-start your Infiniti G37, first, park a vehicle with a fully charged battery close enough to reach both batteries with jumper cables. Connect the positive (red) jumper cable clamp to the positive terminal of the dead battery, then connect the other end of the positive cable to the positive terminal of the charged battery. Next, connect the negative (black) jumper cable clamp to the negative terminal of the charged battery and attach the other end of the negative cable to a metal surface away from the dead battery. Start the engine of the vehicle with the charged battery, and then attempt to start the Infiniti G37. Once started, remove the jumper cables in the reverse order. It is important to follow these steps precisely to avoid damaging the electrical system.

To replace a fuse in your Infiniti G37, locate the fuse box, usually found in the engine compartment or beneath the dashboard. Use the fuse box diagram provided in the owner's manual to identify the specific fuse for the desired component. Gently pull out the fuse using a fuse puller or needle-nose pliers and replace it with a new fuse of the same amperage rating. Properly functioning fuses are essential for protecting electrical circuits from damage caused by overloads or short circuits.

To replace a headlight bulb in your Infiniti G37, first, locate the headlight assembly behind the affected bulb. Disconnect the electrical connector from the bulb, then twist and remove the bulb from its socket. Insert the new bulb into the socket, ensuring it is securely seated, and reconnect the electrical connector. Finally, test the headlight to ensure proper operation. It is important to handle halogen bulbs with gloves or a clean cloth to avoid oil residue from the skin, which can reduce bulb life.

To reset the maintenance reminder in your Infiniti G37, turn the ignition switch to the ON position without starting the engine. Within 10 seconds, press and hold the trip odometer reset button until the maintenance reminder resets. This procedure may slightly vary depending on the model year, so referring to the vehicle's owner's manual is recommended. Resetting the maintenance reminder ensures accurate tracking of future service intervals.

It is recommended to change the oil in your Infiniti G37 every 5,000 to 7,500 miles or every 6 months, whichever comes first. Regular oil changes help keep the engine lubricated and clean, ensuring optimal performance and longevity. Neglecting oil changes can lead to engine damage and decreased fuel efficiency.

The air filter in your Infiniti G37 should be replaced every 15,000 to 30,000 miles or as recommended by the manufacturer. A clean air filter ensures proper air flow to the engine, improving fuel efficiency and reducing emissions. Neglected air filters can lead to reduced engine performance and increased fuel consumption.

The cabin air filter in your Infiniti G37 should be replaced every 15,000 to 25,000 miles or as recommended by the manufacturer. A clean cabin air filter ensures fresh and clean air inside the vehicle, improves HVAC system performance, and protects occupants from dust, pollen, and other airborne particles. Neglected cabin air filters can lead to unpleasant odors, reduced airflow, and potential HVAC system issues.

The spark plugs in your Infiniti G37 should be replaced every 60,000 to 100,000 miles, depending on the specific spark plug type and driving conditions. Worn or faulty spark plugs can lead to engine misfires, reduced fuel efficiency, and rough idling. Replacing the spark plugs at the recommended interval ensures proper combustion, smooth engine operation, and optimized fuel economy.

The recommended coolant for your Infiniti G37 is a mixture of ethylene glycol-based antifreeze and distilled water, in a 50:50 ratio. This coolant mixture provides adequate protection against freezing and overheating, helping to maintain the engine's optimal operating temperature. Regular coolant checks and exchanges are essential for preventing engine damage and maintaining the vehicle's cooling system efficiency.

The recommended tire rotation pattern for your Infiniti G37 is a simple front-to-back rotation. This means that the front tires are moved straight back to the rear, and the rear tires are moved straight forward to the front. This rotation pattern helps ensure even tire wear and prolongs tire life. It is recommended to perform tire rotations every 5,000 to 7,500 miles or as specified by the vehicle manufacturer.

The recommended oil for your Infiniti G37 is synthetic oil with a viscosity of 5W-30. Synthetic oil offers better protection and performance compared to conventional oils, especially in extreme temperatures. It is important to use the correct oil grade and quality to maintain the engine's reliability and efficiency.

The recommended transmission fluid for your Infiniti G37 is Nissan Matic-S automatic transmission fluid. Using the correct transmission fluid is crucial for smooth shifting, optimal performance, and overall longevity of the transmission. Regular checks and fluid exchanges help maintain proper lubrication and cooling of the transmission components.

Brake pads on your Infiniti G37 should be replaced when the friction material thickness is worn down to approximately 3mm. It is also recommended to replace them if you hear squealing or grinding noises while braking. Timely brake pad replacement ensures optimal braking performance and prevents damage to other brake components like rotors and calipers.
