Raise the car and drain the oil

To remove the oil pan of a 2006 Infiniti G35 Coupe, you will first need to raise the car and drain the oil. Here is a step-by-step guide on how to do this:

Step 1: Prepare the Car and Gather Tools

Before you begin, it is important to have the right tools and a clear workspace. Make sure you have a car jack, jack stands, wheel chocks, and a container to catch the drained oil. Check that you are working on a flat surface, such as a garage floor, driveway, or street parking. It is also recommended to refer to your car's owner's manual to identify the specified jack points and weight of your vehicle.

Step 2: Position the Car Jack and Wheel Chocks

Place wheel chocks in front of the tires that will remain on the ground. This is especially important when the rear of the car is lifted as emergency brakes only work on the rear wheels. Position the car jack underneath the frame, preferably at the specified jack points.

Step 3: Raise the Car

Slowly raise the jack until it meets the jack point and becomes slightly difficult to raise. Check that the head and jack point are aligned correctly, and then continue raising the jack. Lift the car slowly and steadily until you reach the desired height. Remember to lift the car only one wheel at a time.

Step 4: Place Jack Stands

Once you have reached the desired height, place jack stands underneath non-articulating points under the car, such as the frame, subframe, or engine cradle. Adjust the jack stands to the desired height to keep the vehicle securely lifted. Gently lower the jack by twisting the pump-action handle or the knob, allowing the frame to rest on the jack stands.

Step 5: Check Stability and Safety

Before proceeding, it is crucial to ensure your safety and the stability of the vehicle. Shake the car slightly to make sure it is firmly set on the jack stands. Never work underneath a vehicle when it is supported only by a jack. Always use jack stands to secure the vehicle.

Step 6: Drive and Cool the Car

Before draining the oil, drive the car for 5-10 minutes and then let it cool for about 10 minutes. This will help the engine oil drain faster.

Step 7: Drain the Oil

Place a container under the car to collect the drained oil. Using a 14mm socket, open the drain plug, which is located under the car. Allow the oil to drain completely, which should take about 10-15 minutes. Close the drain plug when finished.

By following these steps, you will have successfully raised the 2006 Infiniti G35 Coupe and drained the oil, preparing you for the next steps in removing the oil pan. Remember always to work safely and refer to your car's manual for additional information.

Remove the skid plate and bolts

To remove the skid plate and bolts, follow these steps:

First, you will need to raise your Infiniti G35 Coupe on a lift, jack stands, or ramps. Ensure the car is stable when in the air before going underneath it. Next, drive the car for 5-10 minutes and then let the engine cool for about 10 minutes so that the oil drains faster.

Now, locate the engine oil drain plug under the car and place a container underneath it to collect the old oil. Using a 14mm socket, open the drain plug. Then, open the inlet cap in the engine bay to allow the oil to drain faster. The oil should drain out in about 10-15 minutes. Once the oil has drained, close the cap.

At this point, you can remove the skid plate or plastic splash guard/shroud. To do this, you will need to remove the bolts using a 10mm socket. The bolts must be removed in reverse order, as shown in your vehicle's manual. Once all the bolts are removed, carefully pull off the skid plate.

Now, you can access the oil pan and proceed with the rest of the oil pan removal process.

Clean the upper oil pan

To clean the upper oil pan of your 2006 G35 Coupe, you will first need to remove the oil pan. This can be done by following these steps:

• Use jacks and jack stands to lift and support your vehicle.
• Ensure that an oil pan is placed just below the tank from where the oil will flow.
• Remove the mounting bolts and drain the oil.
• Loosen the old pan using a socket.
• Remove the existing oil pan.
• Use a clean rag to wipe away any metal debris.

Once the oil pan has been removed, you can begin cleaning the upper oil pan surface. Here are the steps:

• Use a soft scrubber like a dish sponge or a Scotch-Brite pad to clean the surface.
• Wipe down excess oil using a shop towel.
• Spray a detergent that breaks down oil (such as Simple Green) onto the surface and wipe with a paper towel or shop cloth.
• Remove any remnants of the old gasket. You may need to use tweezers to pull out bits from the bolt holes. Be careful not to scratch the surface.
• Ensure that the surface is thoroughly dried before proceeding to the next step.
• If needed, use a plastic or composite scraper to remove any stubborn deposits or remnants of the old gasket. Do not use metal tools as they can damage the soft aluminum surface.
• Once the surface is clean and dry, you can proceed to install the new gasket and oil pan following the manufacturer's instructions.

It is important to note that working with engine oil can be toxic, so it is advised to use gloves and eye protection during this process.

Install the new oil pan and gasket

To install the new oil pan and gasket for your 2006 G35 Coupe, follow these steps:

Firstly, ensure that the new oil pan is the correct replacement for your car. The oil pan should be compatible with the Infiniti G35 Coupe V6 3.5L AWD model from 2004-2006. The oil pan should not include the oil filter stud or the oil filter check valve.

Now, before installing the new oil pan, clean the surface of the upper oil pan using a soft scrubber, such as a dish sponge or a Scotch Brite pad. Remove any excess oil with a shop towel, then use the pad to wipe down the area. Ensure that all remnants of the old gasket are removed, including from the bolt holes. Use tweezers if necessary to remove any small bits. Be careful not to scratch the surface.

Next, prepare the new gasket. If you are using a liquid gasket, apply it to the new oil pan according to the manufacturer's instructions. If you are using a pre-made gasket, ensure that it aligns perfectly with the bolt holes.

Now, carefully lift the new oil pan into position, ensuring that the holes for the bolts in the gasket and pan match each other. Start installing the bolts by hand, following the correct torque pattern and values specified in your car's manual. Tighten the bolts with a socket wrench, being careful not to overtighten them.

Once the oil pan and gasket are securely in place, you can proceed to refill the engine with new oil. Add the recommended amount of oil for your engine, close the oil filler cap, and check for any leaks. Run the engine for a short period and re-check for drips or leaks. If any leaks are detected, re-tighten the bolts and check again.

Finally, lower the vehicle from the jack stands or lift, ensuring that it is stable before moving on.

This installation guide provides a general overview of the process. For more detailed instructions and torque specifications, refer to a repair manual specific to your vehicle.
