Replacing Oil Pan On Toyota T100: Step-By-Step Guide

Changing an oil pan on a Toyota T100 pickup can be a challenging task. The process involves locating and removing the oil pan bolts/nuts, as well as addressing any sealant or glue that may be holding the pan in place. In some cases, it may be necessary to remove additional components, such as the cross member, steering parts, or the front differential, to access and remove the oil pan. It is important to consult repair manuals or seek advice from experienced mechanics to ensure the job is done correctly and to prevent damage to the vehicle.

Locating and removing the oil drain plug

To locate and remove the oil drain plug of your Toyota T100, follow these steps:

Begin by opening the hood of your Toyota T100 and locating the oil drain plug underneath the vehicle. It is essential to position yourself safely under the vehicle, ensuring you are wearing safety glasses to protect your eyes from any dripping fluids. Engine coolant, brake fluid, and battery acid can be harmful.

Once you have located the oil drain plug, set up your workspace. Place a drain pan or container underneath the plug to catch the draining oil. Before removing the plug, ensure you have the correct replacement part readily available. The Toyota T100 uses an M12 x 1.25 thread oil drain plug.

Now, remove the oil drain plug using the appropriate-sized socket or wrench. Turn the plug counterclockwise to loosen and remove it. Allow the oil to drain completely, ensuring not to spill any on surrounding components.

After the oil has finished draining, replace the oil drain plug. It is recommended to apply a new gasket or washer to the plug before reinstalling to ensure a tight seal. Tighten the plug securely, being careful not to overtighten, as this can cause damage to the oil pan.

Finally, dispose of the drained oil responsibly at a designated location or recycling center. Do not pour used oil down drains or into the environment.

Remember to wear appropriate safety gear and follow safe jacking procedures if your vehicle is too low to access the drain plug.

Draining the oil

To drain the oil from your Toyota T100 pickup, follow these steps:

First, prepare your workspace and gather the necessary tools. You will need an oil drain pan, jack stands, safety equipment, and the correct oil type for your vehicle. It is important to work safely and protect yourself from any fluids that may drip down. Wear safety glasses and gloves to avoid contact with harmful substances such as engine coolant, battery acid, or brake fluid.

Next, open the hood of your T100 and prop it open. Locate the oil drain plug underneath the vehicle. Position your drain pan under the drain plug to catch the drained oil. Before draining the oil, you may need to remove the oil filter, as it is often easier to remove before the oil is drained.

Now, remove the oil drain plug using the appropriate tool. Allow the oil to drain completely into the pan. This may take several minutes. Once drained, replace the drain plug securely. Do not overtighten the plug, as this can cause damage.

If you have not already done so, remove the oil filter. The oil filter on a T100 can usually be removed by hand, but if needed, use an oil filter wrench. Be careful not to damage the sealing surface when removing the filter. Once removed, wipe down the mounting surface to ensure it is clean and free of debris.

After draining the oil and replacing the drain plug, you can now add new oil to your vehicle. Locate the oil fill cap and remove it. Determine the correct oil type and amount for your vehicle, and slowly pour the oil into the fill hole. Use a funnel if needed to avoid spills. Do not overfill the engine with oil. Once the correct amount of oil has been added, replace the oil fill cap securely.

Finally, start your vehicle and inspect for any leaks. Check the oil level with the dipstick and ensure it is at the correct level. If necessary, adjust the oil level accordingly. Remember to dispose of the used oil and filter properly at a designated location or recycling center.

Locating and removing the oil filter

To locate and remove the oil filter on a Toyota T100 pickup, follow these steps:

First, you will need to raise the vehicle and place a drain pan under the plug to catch any falling oil. Next, locate the oil filter, which should be near the drain pan. Before removing the oil filter, it is important to have a drain pan ready to catch any oil that may spill. Once you have located the oil filter, use a wrench to loosen it. Be careful not to drop the oil filter as it may be hot. Place the oil filter in the drain pan to allow any remaining oil to drain.

Now, you can begin cleaning the block surface of the engine. This is an important step to ensure that any dirt or debris is removed before installing the new oil filter. Compare the old and new oil filters to ensure that you have purchased the correct replacement. Lubricate the new oil filter's gasket by applying a small amount of new oil to the gasket surface. This will help to create a tight seal and prevent leaks.

Finally, you can install the new oil filter by hand-tightening it. Ensure that it is secure, but be careful not to overtighten it, as this could damage the gasket and cause leaks.

Adding oil to the new oil filter

To add oil to the new oil filter, follow these steps:

• Purchase a new oil filter and engine oil.
• Jack up the car or place it on ramps to access the oil filter and drain plug.
• Locate the oil filter and drain plug on the passenger side of the front of the car.
• Place a drain pan underneath the drain plug and filter to catch the drained oil.
• Remove the drain plug using a 14mm socket. Allow the oil to drain completely.
• Loosen the filter plug using a 3/8" drive socket wrench and extension if necessary. Remove the plug and set aside.
• Insert a 3/4" OD tube into the hole in the filter housing to drain excess oil. This step is optional and can be skipped if you plan to remove the entire housing with the oil pan drain plug.
• Use a 15/16" socket wrench and the filter cap tool to loosen and remove the filter housing.
• Take out the old filter element and O-ring, cleaning the inside of the housing and engine-side of the housing of any excess oil.
• Install the new filter element and large O-ring, ensuring the O-ring is lubricated and installed correctly.
• Reinstall the filter housing using the filter cap tool and a 15/16" socket. Tighten the housing to 19 ft-lb (228 in-lb).
• Replace the small O-ring in the groove of the filter plug if it fell out during removal. Lubricate the new O-ring and insert it into the groove.
• Reinstall the filter plug and tighten it to 9.5 ft-lb (114 in-lb).
• Reinstall the drain plug and gasket, tightening it to 30 ft-lb (360 in-lb).
• Remove the oil fill cap and add the recommended amount of new oil for your vehicle.
• Reset the "Maintenance Required" light by turning the ignition to "ON" and ensuring "Trip A" is displayed. Turn the ignition "Off" and push and hold the trip button while turning the ignition back to "ON".
• Start the car and check the oil level with the engine at operating temperature to ensure it is at the correct level.

By following these steps, you can successfully add oil to the new oil filter and complete the oil change process for your Toyota T100 pickup.

Reinserting the oil filter

When reinserting the oil filter, you may lose up to a quart of oil depending on your car. This is not harmful to the car and will not speed up the need for another oil change. After changing the filter, top off your oil with a suitable replacement and ensure the levels are correct with the dipstick.

Start the car and check for any leaks. If there are no leaks, you should be good to go.

Some people recommend that you prime your filter first, but this is not necessary for cars with small oil filters. If your filter is easy to reach, there is no harm in doing this. However, if it is not easy to reach, things might get messy.

To avoid a mess, use a plastic cup when you unscrew and take off the filter. This will catch most of the excess oil. You can also prefill the replacement filter with new oil before installing it.
