What You'll Learn
The 1998 Nissan Maxima oil pan is attached to the bottom of the motor
The oil pan is an important component of the car's engine, and it needs to be kept clean and well-maintained to ensure the engine functions properly. Over time, oil pans can develop leaks, which can be caused by a variety of factors such as gasket failure or seal deterioration. If you notice any leaks, it is important to address them promptly to prevent further damage.
When removing the upper oil pan from a 1998 Nissan Maxima, it is important to follow the correct procedure to ensure a safe and efficient process. Firstly, it is recommended to clean the engine and engine bay thoroughly. This can be done using a suitable cleaner, such as Berryman's B12 carb and throttle body cleaner. However, it is important to exercise caution when drying off painted surfaces to avoid any potential damage.
The next step is to scrape away any old gasket material from the crevices of the oil pan. This step is crucial to ensure that the new liquid gasket can adhere properly to the metal surface. Once the surface is clean and prepared, a small amount of liquid gasket can be applied to hold the new upper oil pan in place.
It is worth noting that the oil pan removal process can be time-consuming and may vary in duration depending on one's level of experience. Additionally, different models of the Nissan Maxima may have variations in their oil pan design, so it is always a good idea to consult a professional or a trusted mechanic for guidance on specific models.

Rubber sealing strips are used in the two-piece oil pan
The 1998 Maxima features a two-piece oil pan, which differs from the conventional one-piece oil pan in that it uses rubber sealing strips instead of a standard oil pan gasket. These rubber sealing strips are placed along the crankshaft saddles at the front and rear of the engine block. This design choice is intended to prevent oil leaks, a common issue with oil pans.
When removing the upper oil pan of a 1998 Maxima, it is important to be prepared to spend a significant amount of time, potentially several hours, under the car. It is also recommended to clean the engine and engine bay during the process, using a suitable cleaner such as Berrymans B12 carb and throttle body cleaner.
To remove the upper oil pan, start by draining the engine oil and removing the oil filter. Then, remove the Y-Pipe and its associated nuts, being careful not to break a stud as they may be rusted on. Use a suitable floor jack or an engine hoist to support the transmission during this process.
The next step is to remove the ten 10mm bolts holding the steel oil pan in place, followed by the removal of the oil strainer and its bolts. At this point, you can begin to apply the liquid gasket. Scrape out any old gasket material from the crevices and apply a small amount of liquid gasket to hold the new gasket in place while installing the upper oil pan.
It is important to note that the rubber sealing strips used in the two-piece oil pan design of the 1998 Maxima are not standard oil pan gaskets. These strips are specifically designed to seal the crankshaft saddles at the front and rear of the engine block. Therefore, when reinstalling the upper oil pan, ensure that you use the appropriate liquid gasket sealant on the sealing surfaces between the sides of the engine block and the upper oil pan, as well as between the upper and lower oil pan sections.

Removing the oil pan can take 5-7 hours
The oil pan is an essential component of your car's engine lubrication system. It holds the oil, allowing it to circulate and keep the engine components lubricated and cool. Removing the oil pan from a 1998 Maxima can take anywhere from 5 to 7 hours, depending on your experience and the condition of the oil pan. Here's a step-by-step guide to help you through the process:
Step 1: Drain the Engine Oil
Place a drain pan under the oil pan and unscrew the drain plug to let the oil out. Once the oil has drained completely, screw the plug back in lightly to keep dirt and debris out.
Step 2: Remove Bolts and the Oil Pan
Using a wrench, remove the bolts around the oil pan. If the pan is difficult to remove, gently tap it with a rubber mallet to loosen it. Be cautious not to damage any surrounding components.
Step 3: Clean the Gasket Surface
Remove any old gasket material from the surface where the oil pan meets the engine block. It is crucial to clean this surface thoroughly to ensure a proper seal with the new pan.
Step 4: Prepare the New Gasket
Depending on the type of new gasket you have, you may need to apply a liquid gasket sealant. Follow the manufacturer's instructions for proper application.
Step 5: Install the New Oil Pan
Line up the new oil pan and start bolting it into place. Refer to the tightening sequence recommended in your car's manual, and be careful not to over-tighten the bolts.
Step 6: Refill the Engine Oil
With the new oil pan securely in place, remove the drain plug again and refill the engine with the correct type and amount of oil.
Step 7: Test for Leaks
Start the engine and let it run for a few minutes. Inspect the new oil pan and drain plug for any signs of leaks. If no leaks are detected, turn off the engine and carefully lower the car back to the ground.
Remember, taking your time and doing the job right is more important than rushing through it. If you encounter any issues or are unsure about a step, don't hesitate to seek advice or assistance from a professional.

A universal joint is required for removal
To remove the upper oil pan on a 1998 Maxima, a universal joint is required. This is because the upper oil pan is located at the bottom of the engine, and the universal joint is needed to reach and remove the various bolts and nuts holding the pan in place.
The process of removing the upper oil pan on a 1998 Maxima is a complex and time-consuming task, which may take several hours to complete, even for those with experience. It is important to be prepared to spend a significant amount of time under the car, and to have the necessary tools and equipment ready. In addition to a universal joint, other tools required include a 1/4" ratchet extension breaker bar, 10mm, 12mm and 14mm sockets (shallow and deep), a gasket scraper, a flat-head screwdriver, and a rubber mallet.
The first step is to drain the engine oil and remove the oil filter. Next, the fan and fan shroud need to be removed, and the motor mount bolts must be loosened or removed. It is important to be careful not to damage the oil level float sensor or other sensitive components. Once the fan and shroud are removed, the engine can be jacked up by the crank pulley to access the upper oil pan.
The upper oil pan is held in place by multiple bolts and nuts, which must be removed carefully. This includes the 10mm bolts holding the steel oil pan, the 12mm bolts for the oil strainer, and the 12mm nuts for the Y-Pipe. In some cases, liquid wrench may be needed to loosen rusted nuts. After removing these components, a floor jack or engine hoist can be placed in a safe location to support the transmission during the next steps.
Finally, the upper oil pan can be removed by carefully prying it off using a flat-head screwdriver or a specialized tool recommended by the dealer. It may take some time and patience to remove the pan completely, as it may be stuck in certain spots. Once removed, the old gasket material should be scraped off, and the new liquid gasket can be applied to install the new upper oil pan.
