Remove the old oil pan drain plug

Removing the old oil pan drain plug from your 2008 Nissan Quest is a simple task that can be done in a few steps. Firstly, ensure that your car is parked on a stable and level surface. Using a hydraulic jack or a manual jack, lift the car to provide adequate clearance to access the oil drain plug. The oil drain plug is typically located at the lowest point of the oil pan, which is situated at the bottom of the engine.

Once you have located the oil drain plug, the next step is to loosen it. Using a correct-sized socket wrench, turn the oil drain plug in an anticlockwise direction to loosen it. If the plug is stuck, there are a few techniques you can try. Firstly, try warming up the car by letting it idle or taking a short drive. This can help to loosen any sludge or buildup around the plug. Another method is to use a hammer to gently tap the oil drain plug in the right direction to loosen it, being careful not to damage the plug or its teeth.

If the plug is still stuck, you can try using a rust remover or lubricant by spraying it onto the plug and waiting a few minutes before attempting to remove it again with the socket wrench. You can also try using a Gator Grip, which is a universal wrench socket that works with various plugs, sockets, and bolts.

If the plug is stripped, you may need to use a flathead screwdriver and a hammer to apply some taps on the head of the plug to create sheer force. Additionally, applying heat to the plug with a heat gun can cause it to expand, making it easier to remove once it cools down. This process also helps break down rust bonds.

If all else fails, don't hesitate to seek professional help. A qualified mechanic will have the necessary skills and tools to safely remove the stuck oil drain plug and advise on any further repairs that may be needed.

Clean the mating surfaces of the transmission and oil pan

To clean the mating surfaces of the transmission and oil pan, first, carefully remove all the gasket material from the transmission oil pan and the mating surface on the transmission. A razor blade may be useful for this step.

Next, clean the mating surfaces. You can use a wire brush to remove any residue. Alternatively, you can use a metal brush-like sandpaper or a brush wheel bit attached to a drill. You can also use brake cleaner to clean the mating surfaces.

Finally, apply a light coat of high-tack gasket sealant to the transmission oil pan. Carefully place the gasket on the pan, lining up the holes on the gasket with the holes on the pan. Allow the sealant to set for a few minutes so that the gasket won't shift during installation.

Replace or reuse the gasket

When replacing the oil pan gasket, it is important to refer to a service manual for your specific vehicle. This will help you identify all the oil-pan bolt locations, as some may be obscured behind other parts. The service manual will also describe vehicle-specific procedures, such as if the crankshaft needs to be rotated before the pan can be removed.

Before removing the oil pan, it is recommended to clean the engine with a degreaser to easily trace any external oil leaks to their source. If the evidence leads to the top of the oil pan, the solution will be more labour-intensive.

• Obtain the appropriate oil pan gasket replacement. Gasket materials vary depending on the type of metal they are intended to seal. Name-brand gaskets typically come with any necessary sealants.
• While the oil is draining, remove the splash shield and bell housing cover.
• In front-wheel-drive vehicles, the oil pan is often mated to the transaxle. Other accessories, such as the exhaust manifold support and air-conditioning bracketry, might need to be detached.
• Identify all oil-pan bolt locations using the service manual.
• Remove the wheel-well-liner pieces to ease access to the bolts.
• Once all bolts are removed, the pan can be dropped. If necessary, tap it lightly with a mallet to break the seal.
• Scrape off any gasket residue and clean all sealing surfaces thoroughly with a solvent. Also, clean the inside of the oil pan and inspect it for cracks.
• Install the new gasket according to its instructions. Some gaskets use regular grease to hold them in position.
• Use a thread sealer, if specified, then torque the oil pan bolts to the specified torque in a spiral pattern, beginning in the centre.
• Reattach any accessory brackets, refill the crankcase with oil, start the engine and inspect for leaks.

Regarding reusing the gasket, some sources suggest that it is generally safe to reuse copper gaskets several times. Copper gaskets can be annealed to restore their original softness and sealing ability. This involves heating the gasket with a small torch until it is red-hot, then allowing it to cool naturally or quenching it in water. However, quenching copper in water is typically done to harden the metal, which is not desirable in this case.

Other sources recommend replacing the gasket with each oil change, especially for crush washers, which are meant to be replaced each time. Reusing the washer can result in tighter torquing of the bolt to prevent leaks, which can lead to stripped pan threads.

In conclusion, while reusing a copper gasket may be possible after annealing, it is generally recommended to replace the gasket with each oil change, especially for crush washers, to ensure a proper seal and prevent damage to the oil pan threads.

Install the new oil pan drain plug

Now that you have removed the old oil drain plug, it's time to install the new one. This process is fairly straightforward but requires careful attention to detail to avoid any leaks. Here is a step-by-step guide on how to install a new oil pan drain plug in your 2008 Nissan Quest:

• Prepare the new drain plug and gasket: Before you begin, make sure you have the correct replacement parts for your vehicle. You will need a new drain plug and a gasket. The gasket can be made of copper, aluminum, or rubber. It is important to use the right type of gasket specified for your vehicle.
• Clean the oil pan: Before installing the new drain plug, clean the oil pan thoroughly to remove any dirt, debris, or residue. This will help ensure a proper seal and prevent leaks.
• Insert the new drain plug: With the oil pan clean, take the new drain plug and insert it into the opening in the oil pan. Make sure it is positioned correctly and securely in place.
• Tighten the drain plug: Using a socket wrench or your hand, tighten the drain plug. It is important not to overtighten the plug, as this can strip the threads or damage the gasket. Refer to your Nissan Quest service manual for the recommended torque specifications.
• Check for leaks: Once the new drain plug is installed, check the area for any signs of leaks. If the gasket was installed correctly and the drain plug is tightened properly, there should be no leaks.
• Refill engine oil: After confirming that the new drain plug is secure and there are no leaks, you can proceed to refill your engine with new oil. Follow the recommended oil type and quantity specified for your Nissan Quest.
• Run the engine: Start your engine and let it run for a few minutes. This will allow the oil to circulate and build up pressure. Check the oil pressure gauge to ensure it is within the normal range.
• Check oil level: After running the engine, turn it off and allow the oil to drain back into the pan for about 5-10 minutes. Check the oil level and adjust it accordingly to reach the recommended level.
• Test drive: Once you have confirmed that the oil level is correct and there are no leaks, take your Nissan Quest for a short test drive. This will help you ensure that the oil system is functioning properly and that there are no unusual noises or issues.
• Final check: After your test drive, check the oil level again and inspect for any signs of leaks. If everything looks good, you have successfully installed your new oil pan drain plug!

Remember to dispose of the old engine oil and the drained oil properly at a designated location or recycling center. Always refer to your vehicle's service manual for specific instructions and torque specifications to avoid any damage during the installation process.
