• Ratchet: A ratchet is a handle that snaps into one end of a socket and allows you to tighten or loosen fasteners. It has a mechanism that lets you engage and tighten the fastener when swung clockwise and turn freely when swung counterclockwise.
• Pry bar: This is used in conjunction with sockets and extensions to remove certain bolts and nuts.
• Other tools: You'll also need a screwdriver, scraper, gasket, motor oil, drain plug gasket, and 3M spray adhesive.

It's important to have the right tools and equipment when working on your Honda Accord to ensure a safe and successful repair or replacement.

Jack up the car, drain the oil, and remove the oil drain plug

Jacking up your car is an essential step in replacing the oil pan of your 97 Honda Accord. Here is a detailed, step-by-step guide to help you through the process of jacking up the car, draining the oil, and removing the oil drain plug.

Jacking Up the Car

First, find a safe place to pull over. Get off the road and away from traffic. Ideally, you want to be on solid, level ground, such as a parking lot. Turn off the engine, put the car in park, and engage the parking brake. If possible, use something like a brick or a large rock to block the tire opposite the corner you'll be jacking up. This adds an extra layer of security to prevent the car from rolling.

Now, locate the jack and jacking points. The jack is usually stored in the trunk or under the cargo-floor cover in an SUV. The jacking points are reinforced metal ribs specifically designed to lift the vehicle and are typically located under the car's rocker panels, near the front and rear wheels. Consult your Honda Accord's owner's manual for the exact locations.

Once you've located the jack and jacking points, position the jack. Most car jacks have a slot that slips onto the jack point's reinforced rib. However, your car may vary, so check your owner's manual. If necessary, spin the jack down first so it fits under the car.

Now, it's time to jack up the car. Turn the jack handle clockwise slowly until the desired tire is off the ground. Ensure that the jack remains straight up and down as it lifts the car. If you plan to work under the car, it's crucial to place a jack stand under the rocker panel for added safety.

Draining the Oil

To drain the oil, locate the oil drain plug. It is typically found at the lowest point on the oil pan, which is attached to the bottom of the engine. It may be on the bottom or side of the oil pan.

Before removing the plug, place a pan underneath to catch the draining oil. Then, use a 17 mm wrench or socket to remove the oil drain plug. Allow the oil to drain completely. If the oil is still relatively new and in good condition, you can reuse it. Otherwise, install a new oil filter and fresh oil.

Removing the Oil Drain Plug

After the oil has drained, reinstall the oil drain plug. First, clean the plug and threads, checking for any damage or wear. If there is any damage, replace the gasket or washer. Then, tighten the plug by hand as far as you can; you don't want to force it and risk stripping the threads. Finally, torque the plug to the specified tightness using the correct tools.

By following these steps, you can safely jack up your 97 Honda Accord, drain the oil, and remove the oil drain plug, setting the stage for replacing the oil pan. Remember to always exercise caution when working on your vehicle and refer to your owner's manual for specific instructions pertaining to your car.

Remove the exhaust pipe and any stiffening braces

To remove the exhaust pipe and any stiffening braces from your 1997 Honda Accord, you'll need to follow a few careful steps. Here's a detailed guide to help you through the process:

Firstly, make sure you have the necessary tools and safety equipment. For this task, you'll need a 14 mm socket, an extension, a pry bar, and a suitable jack to raise the front of your car. It's also recommended to have a pry bar and a torque wrench. As always, ensure you are wearing appropriate safety gear, including gloves and eye protection, and that your car is securely raised and blocked before you start.

Begin by spraying WD-40 on the front and rear front exhaust pipe nuts. Let it soak in for a while. Then, use your 14 mm socket, extension, and pry bar to remove these nuts. There should be six in total. Once they are removed, you can carefully pry off the front exhaust pipe. You may need to use a screwdriver to help remove it completely.

Next, locate the lower bracket nuts for the front exhaust pipe to block. These are just behind the oil pan. Use a 12 mm socket and ratchet to remove these nuts. With these nuts removed, you can now detach any stiffening braces attached to this area. Braces are often used to reinforce the chassis and suspension of a car, so be sure to identify and remove any braces connected to the exhaust or oil pan.

At this point, you should have successfully removed the exhaust pipe and any associated stiffening braces. It's important to work slowly and carefully to avoid damaging any other components or the car's body. Now you can continue with the next steps in your oil pan replacement procedure. Remember to refer to a qualified mechanic or a detailed Honda Accord repair manual for further guidance if needed.

Finally, when you're ready to reinstall the components, ensure that you follow the correct torque specifications for the bolts and nuts. For the oil pan bolts and nuts, the recommended torque is 10 ft-lbs. It's also important to tighten them in a criss-cross pattern from the middle to the outside, being careful not to overtighten.

Remove the oil pan bolts and drop down the oil pan

To remove the oil pan bolts and drop down the oil pan of your 1997 Honda Accord, follow these steps:

First, make sure the car is properly supported and elevated, so you can safely work underneath it. You don't want the car to be supported only by a flimsy jack.

Next, remove the oil drain plug using a 17 mm wrench or socket. Once the oil has drained out, you can start to remove the oil pan bolts.

Use a 14 mm socket, extension, and pry bar to remove the front and rear front exhaust pipe nuts. There should be six in total. Then, use a 12 mm socket and ratchet to remove the lower bracket nuts for the front exhaust pipe to block, which is just behind the oil pan. You may need to use a screwdriver to pry on the bracket.

Now, use a 14 mm socket, extension, and pry bar to remove the bolts for the front and rear beam. Then, use a 10 mm socket to remove the bolts for the flywheel cover. If your car is an automatic, you will also need to remove the three 12 mm bolts for the transmission shifter cable cover.

At this point, you should be able to remove all the bolts and nuts for the oil pan. The oil pan should drop down, but in some cases, you might need to gently pry it a bit.

It is important to clean the oil pan and the block surface thoroughly before installing a new gasket. Make sure that the little metal rings at the corners do not stick up on the block, as this can cause an oil leak. You can use a propane torch to heat up and soften any old pan gasket that is baked onto the pan.

Clean the oil pan and block surface, and apply a new gasket

To clean the oil pan and block surface, and apply a new gasket, follow these steps:

Firstly, make sure you have the right tools for the job. You will need a variety of metal and plastic scrapers to aid in removing the old gasket material. Flat-blade paint removal-type scrapers are the most popular, along with carbide scrapers. You can also use a razor blade (metal or plastic) mounted in a holder to remove any remaining gasket material. When cleaning aluminum surfaces, be sure to use a plastic scraper or plastic razor blade to avoid damaging the soft metal.

Next, prepare the oil pan and block surface by removing any old gasket material, carbon, and dirt. Use the scrapers to carefully scrape away the old gasket, being careful not to gouge the surface. You can also use a wire wheel in a die grinder for heavy cleaning, but be cautious and "feel" the surface to preserve the finish. A coarse wire wheel can be used on cast iron surfaces, while a fine wire wheel is suitable for both cast iron and aluminum.

Once the surface is clean, use a degreaser to remove any remaining oil or grime. Spray the degreaser onto the surface and let it sit for a few minutes to break down the oil. Then, use a stiff-bristled brush to scrub the surface clean, making sure to get into all the nooks and crannies. Rinse the surface with water to remove any remaining degreaser.

Before applying the new gasket, use sandpaper to rough up the surface. This will help the new gasket material adhere better. Be sure to sand both surfaces evenly.

Now you are ready to install the new gasket. Follow the instructions that came with your gasket kit, and be sure to torque the bolts to the correct specifications. Apply a small amount of Honda bond to the curved edge of the pan gasket that will mate to the block and the opposite side. Stick the pan gasket onto the block, making sure to line up all the holes properly.

Finally, reinstall the oil pan, making sure all the bolts and nuts are started before tightening them. Tighten the bolts in a criss-cross pattern from the middle to the outside, being careful not to overtighten. Once all the bolts are tightened, reinstall the rest of the components you removed and add oil. Start the engine and let it run to check for any leaks.
