Changing Oil Pan On A 2000 Honda Accord: Step-By-Step Guide

Replacing the oil pan on a 2000 Honda Accord is a complex task that requires a range of tools and mechanical expertise. The process involves raising the car, removing the old oil pan, and installing a new one, along with a new gasket or sealant. This job is made more challenging by the limited space to work underneath the car, and the need to remove or adjust various components, such as the exhaust pipe, engine mount, and subframe bolts. It is crucial to ensure the car is properly supported to avoid serious injury or death if it falls. While it is possible for a skilled amateur to replace the oil pan, it is a time-consuming and physically demanding task, and incorrect installation can lead to oil leaks.

Remove the exhaust pipe and some stiffening braces

To remove the exhaust pipe and stiffening braces from your 2000 Honda Accord, you'll need to follow a few careful steps. Firstly, it's important to note that this is a complex task and you may require additional tools and equipment, so ensure you have everything you need before beginning.

Begin by raising your car on a hoist or jack to give you enough space to work underneath. You will also need to drain the engine oil. Once this is done, disconnect the negative cable from the battery, followed by the positive cable. Remove the battery and the air cleaner assembly.

Next, you'll need to remove the transmission mount/bracket assembly and the front and rear mount bolts. You may also need to remove the suspension lower arm ball joint and the driveshaft on the left side, as well as the nuts securing the transmission lower front and rear mounts.

At this point, you should be able to lift the transmission slightly using a jack. This will give you access to the stiffening braces. Stiffening braces, or strut braces, are metal bars that connect the left and right strut towers of a car, reinforcing the frame and reducing chassis flex. To remove them, you may need to pry or cut them, depending on their condition and your tools.

With the braces removed, you can now focus on the exhaust pipe. Exhaust pipes can be tricky to remove, and you may need to consult a mechanic or a specific guide for your car model. However, the basic process involves unbolting the pipe from the manifold and carefully lowering it away from the vehicle. Ensure you have a clear workspace and that the exhaust system has cooled down before beginning this step.

Once the exhaust pipe and stiffening braces are removed, you can continue with the rest of the oil pan replacement process. Remember to consult a professional or a detailed guide if you're unsure about any steps, and always put safety first when working on your vehicle.

Remove the engine mount and raise the engine

To remove the engine mount and raise the engine of a 2000 Honda Accord, follow these steps:

First, ensure you have the necessary tools and a replacement engine mount. You will need a floor jack, jack stands, a scrap piece of 2x4 wood, a ratchet, angle pliers, and the appropriate sockets and extensions for your ratchet. It is also recommended to have a new vacuum hose and bolt that goes through the front engine mount. Additionally, you may want to place a box under the engine to catch any dripping fluids.

Next, safely lift your Accord. Place jack stands under the reinforced metal parts of the vertical crossbeams, following the jacking instructions in your owner's manual. Ensure your parking brake is set and the car is in gear or in park if it is an automatic.

Now, you can begin to remove the engine mount. Pop off the old vacuum hose connected to the faulty front engine mount using angle pliers. Then, go into the engine bay and remove the coolant reservoir and the front mount strap. Remove the mounting bolt that goes into the engine, followed by the four bolts holding the mount in place.

At this point, you can gently crank up the floor jack to lift the engine off of the engine mounting. Be careful, as it is a tight fit with all the hoses and fans around the part. Once the engine is lifted, remove the old engine mounting.

To install the new engine mount, simply follow the above steps in reverse. Make sure to torque the bolts to the manufacturer's specifications.

Use a sealant or a gasket

When replacing the oil pan on a 2000 Honda Accord, you have the option to use a sealant or a gasket to secure the oil pan. The original oil pan on a 2001 Honda Accord EX 4-cylinder was secured using only a sealant. You can choose to use a rubber gasket with a little sealant on the corners or just the sealant on its own.

If you decide to use a sealant, it is recommended to use a red high-temp sealant such as Permatex. You should let the sealant skin over for about 20 minutes before putting the pan back on.

If you prefer to use a gasket, you can use a FelPro oil pan gasket. The Honda shop manual calls for a gasket with a tiny amount of RTV (Room Temperature Vulcanizing) sealant to secure the gasket to the pan for handling purposes.

Remove the oil drain plug

To remove the oil drain plug from a 2000 Honda Accord, first locate the oil pan and drain plug. The drain plug is usually located at the lowest possible point on the oil pan, which is attached to the bottom of the engine. It may also be located on the side of the oil pan to better protect it from damage.

Once you've located the drain plug, use a 17mm wrench or socket to loosen it. Only use the wrench for about half a turn. Position an oil drain pan underneath the drain plug, and then loosen the drain plug by hand until it is free and oil begins to flow out.

Watch the draining oil for any shiny specks, as metal flakes in the oil could indicate a serious problem inside the engine. While the oil is draining, wipe down the drain plug with a clean rag or towel, and remove the drain plug gasket. Replace the drain plug gasket with a new one, ensuring that the new gasket fits over the threads and sits against the head of the bolt.

Wipe the area on the oil pan around the drain plug hole with a clean rag or towel. Reinstall the drain plug and tighten it with a wrench until it is snug. Do not overtighten the drain plug, as this may strip the threads or crack the oil pan.

Remove the oil filter

To remove the oil filter from a 2000 Honda Accord, you will need to follow these steps:

Firstly, locate the oil filter. The oil filter on a Honda Accord is located just aft and above the oil pan. It is positioned at the back of the engine, almost directly above the drain plug.

Next, place an oil drain pan underneath the oil filter to catch any dripping oil. You may need to use an oil filter removal tool if the filter is stuck. Turn the oil filter counter-clockwise to loosen and remove it. Ensure that you are wearing clean gloves, as you will need to dip your finger into the new oil and evenly rub a thin layer of oil around the rubber gasket of the new oil filter.

Now, use a clean rag or towel to wipe down the oil filter threads and contact area on the engine. This will ensure that the new oil filter is installed correctly and securely.

Finally, use your hand to screw the new oil filter into place over the oil filter threads. Hand-tighten it until it is snug. Do not over-tighten, as you will still need to be able to remove it by hand next time.

You have now successfully removed and replaced the oil filter on your 2000 Honda Accord.
