What Is the Firing Order for the 2012 Infiniti G37?

The firing order for the 2012 Infiniti G37 is 1-2-3-4-5-6.

2012 Infiniti G37 Firing Order

The 2012 Infiniti G37 firing order is essential for its smooth running. Starting with the basics, the firing order is the sequence in which the cylinders of the engine fire. It has a direct effect on how your vehicle functions, as when misfiring happens, it can affect performance and even lead to costly repairs. This makes knowing the firing order crucial for your Infiniti G37s smooth operation.

For the 2012 Infiniti G37, ignition in a 6-cylinder engine comes clockwise from the passenger side front cylinder to back cylinder of that side, then continues on to driver side front cylinder and counterclockwise around to back cylinder. This is followed by the power strokes for each cylinder respectively, repeating four times for each full engine cycle: 1-4-2-6-3-5. Knowing this firing order and keeping up regular maintenance can help ensure that your Infiniti G37 will continue to run optimally without any unfortunate misfiring issues or worse.

2012 Infiniti G37 Firing Order

The 2012 Infiniti G37 is a luxurious midsize sedan that offers powerful performance and plenty of features. The G37 is powered by a 3.7-liter V6 engine, and its firing order is important to understand in order to get the most out of the vehicle. Here well take a look at the engine specifications, transmission system, firing order, and cross reference and compatibility information for the 2012 Infiniti G37.

Engine Specifications

The engine used in the 2012 Infiniti G37 is a 3.7-liter V6, which produces 330 horsepower and 270 lb-ft of torque. It utilizes a variable valve event and lift system (VVEL) for improved performance, fuel efficiency, and emissions control. The engine also features Nissans advanced EGR system for reduced emissions.

Transmission System

The 2012 Infiniti G37 comes with a standard six-speed manual transmission or an optional five-speed automatic with Adaptive Shift Control (ASC). The manual transmission offers crisp shifts and provides improved fuel economy compared to the automatic transmission. The automatic transmission also has an available Sport mode for more aggressive shifting when desired.

Firing Order

The firing order for the 2012 Infiniti G37 is 1-2-3-4-5-6 for both the V6 3.7L engine (VQ37VHR) and the VQ35HR engines used in earlier model years of the G37. This firing order ensures that each cylinder receives its spark at the correct time so that all cylinders fire in sequence as designed by Nissan engineers.

Firing Sequence

For both engines, each spark plug fires one time per revolution of the crankshaft, starting with cylinder 1 on compression stroke one (TDC), then cylinder 6 on compression stroke two (TDC + 180). This pattern continues until all six cylinders have fired once per revolution of the crankshaft, resulting in smooth operation of your vehicle’s engine.

Ignition Timing Adjustment

It’s important to note that when resetting or adjusting your ignition timing, you should always start with cylinder 1 at TDC compression stroke one before advancing or retarding any other cylinders in order to ensure accurate timing across all cylinders as per Nissan’s specifications. Failing to do so could result in misfires or poor running performance from your vehicle’s engine due to incorrect ignition timing values being set across all cylinders.

Cross Reference & Compatibility Information

When replacing any components related to your vehicle’s firing order such as spark plugs & wires or distributor caps & rotors it’s important to make sure they are compatible with your specific year & model of vehicle as well as its engine type (VQ35HR or VQ37VHR). Doing so will ensure proper fitment and operation of these components as designed by Nissan engineers while also avoiding any potential issues related to improper installation such as misfires or poor running performance from your vehicles engine due to incorrect components being used during installation or replacement procedures.

Common Issues & Troubleshooting With G37 Firing Order

In some cases it may be necessary to troubleshoot any issues related to your vehicles firing order such as misfires or poor running performance from its engine due to incorrect ignition timing values being set across all cylinders caused by worn out spark plugs/wires or problematic distributor caps & rotors not properly distributing voltage across all cylinders correctly resulting in inconsistent ignition timing values being set across all cylinders causing misfires under certain driving conditions due improper electrical signal distribution from these components resulting in incorrect firing sequences through each cylinder during operation causing issues with running performance from your vehicles engine under certain driving conditions.

Maintenance Schedule and Requirements

The 2012 Infiniti G37 Firing Order requires regular maintenance to ensure the engine is running properly. It is important to check all components of the engine, including the spark plugs, fuel injectors, ignition coils, and other related components. The firing order should be checked regularly and changes should be made if necessary. Professional diagnosis is highly recommended before making any changes to the firing order.

A few of the most important maintenance tasks for the G37 firing order include:

  • Spark Plug Inspection: Inspect spark plugs for wear or corrosion and replace them if necessary. This will help ensure that the engine runs smoothly.
  • Fuel Injector Cleaning: Clean fuel injectors regularly to prevent clogging and ensure proper fuel delivery.
  • Ignition Coil Check: Check ignition coils for any signs of damage or wear and replace them if necessary.
  • Valve Adjustment: Valves should be adjusted periodically to ensure they are operating correctly.

It is also important to check all hoses, belts, filters, and other components on a regular basis. This will help prevent damage or wear due to age or environmental conditions. Regularly checking these components can also help identify problems before they become more serious.

Professional Diagnosis Recommended Before Changes

When making any changes to the firing order of a 2012 Infiniti G37, it is highly recommended that you have a professional diagnose the issue first. A professional mechanic can identify any potential problems with your engine’s performance and make recommendations for corrections or repairs if needed.
