Preparation:
1. Park the vehicle on a level surface and make sure the engine is cool.
2. Put on safety goggles and gloves to protect yourself.
3. Gather your tools, including an oil drain pan, a ratchet, a socket wrench, and a flat-head screwdriver.
Step 1: Drain the Oil
1. Locate the oil drain plug on the bottom of the oil pan. It is usually a 17mm bolt.
2. Place the oil drain pan underneath the oil drain plug to catch the draining oil.
3. Loosen the oil drain plug with the ratchet and socket wrench. Allow all the oil to drain into the pan.
4. Replace the oil drain plug once the oil has completely drained. Tighten it securely.
Step 2: Remove the Oil Pan Bolts
1. Locate the oil pan bolts around the perimeter of the oil pan. They are usually 10mm bolts.
2. Use the ratchet and socket wrench to loosen and remove all the oil pan bolts. Be careful not to drop any of the bolts into the oil pan.
Step 3: Remove the Oil Pan
1. Once all the oil pan bolts are removed, gently pry the oil pan off the engine block using the flat-head screwdriver.
2. Be careful not to spill any remaining oil.
Step 4: Clean the Oil Pan
1. Clean the oil pan thoroughly using a degreaser and a rag.
2. Remove any old gasket material from the oil pan and the engine block.
Step 5: Install the New Oil Pan Gasket
1. Apply a thin bead of RTV silicone gasket maker to the new oil pan gasket.
2. Place the new oil pan gasket on the engine block. Make sure it is seated correctly.
Step 6: Reinstall the Oil Pan
1. Gently place the oil pan on the engine block, aligning the gasket with the bolt holes.
2. Reinsert the oil pan bolts and tighten them securely with the ratchet and socket wrench.
Step 7: Refill the Oil
1. Locate the oil filler cap on the top of the engine. It is usually marked with an oil can symbol.
2. Remove the oil filler cap and use a funnel to pour in new engine oil.
3. Refer to your vehicle's owner's manual for the recommended oil type and amount.
Step 8: Check for Leaks
1. Start the engine and let it run for a few minutes.
2. Check underneath the vehicle for any leaks from the oil pan. If there are leaks tighten the oil pan bolts a little more.
Once you have completed these steps, the oil pan on your 1995 Toyota 4Runner should be successfully removed and replaced. Remember, if you are not comfortable performing this task, it is best to consult a professional mechanic.
