What You'll Learn
What is an oil pan?
An oil pan is a vital part of a vehicle's engine lubrication system. It is attached to the bottom of the engine and holds the oil that will be circulated through the engine to keep its parts lubricated and reduce friction, allowing everything to work smoothly and prevent damage. The oil pan is large enough to hold all the oil in the engine.
The oil pan has an oil drain plug, which is removed when draining the oil. On all engines, there is an oil pickup located in the pan that is connected to the oil pump. On some engines, the pump pickup tube is also located inside the oil pan. The oil pan is sealed with an oil pan gasket to prevent oil leaks. Gaskets can wear out over time, and oil pans can be damaged by external impacts, which can cause leaks.
Oil pans are usually only replaced when they are damaged, and they rarely need to be replaced otherwise. They can last for the lifetime of the vehicle. However, a leaking oil pan can cause serious issues, so it is important to regularly inspect the oil pan for any signs of damage or leaks and replace it if necessary.

When to replace an oil pan
The oil pan is a durable part that can last the lifetime of a Toyota Corolla. However, it may need to be replaced due to external damage, such as a sharp impact with a hard surface at high speed. The main symptom of a damaged oil pan is an oil leak underneath the engine of your car. The oil that leaks will range from dark brown to dark black. If the leak is large enough, the oil pressure or low oil level warning light will come on.
If you see oil puddles or streaks of oil underneath your vehicle, you should get your oil pan inspected by a professional mechanic. Oil pan issues can lead to catastrophic engine damage if left unattended.
The cost of replacing an oil pan in a Toyota Corolla varies depending on the model year and location, but it typically ranges from $411 to $1281.35. The labour costs are estimated to be between $196 and $259, while the parts are priced around $102 to $206.

How to replace an oil pan
The oil pan is located at the bottom of the engine and is responsible for holding the engine oil. The oil pan is typically durable and can last the lifetime of the car. However, it may need to be replaced due to external damage or a worn-out oil pan gasket. Here is a step-by-step guide on how to replace an oil pan:
Step 1: Drain the Oil and Remove the Old Oil Pan
Start by draining the oil from the engine. Locate the oil drain plug at the bottom of the oil pan and undo it to allow the oil to drain completely. Once the oil has drained, proceed to remove the old oil pan. Identify the oil pan bolt locations on the motor mount and gently remove the bolts to detach the oil pan.
Step 2: Clean the Engine Block Surface
After removing the old oil pan, thoroughly clean the engine block surface. Use a chisel or appropriate tool to remove any debris or residue from the engine block, being careful not to damage the engine components.
Step 3: Prepare the New Oil Pan
Scrape off any residual matter or debris from the old oil pan gasket on the engine block. Refer to the manufacturer's recommendations for the type of new oil pan gasket or seal to use. Ensure you have a new oil filter and motor oil ready for installation.
Step 4: Install the New Oil Pan
Align the new oil pan correctly and tighten each bolt according to the manufacturer's specifications. Refer to the user manual or a repair guide for the correct torque settings and bolt tightening sequence.
Step 5: Refill the Oil and Check for Leaks
Once the new oil pan is securely installed, refill the engine with new motor oil. Start the vehicle and check for any oil leaks around the oil pan and gasket. Ensure the oil pressure light is off and the oil level is correct.
Notes on Oil Pan Replacement:
- Oil pan replacement can vary in difficulty depending on the vehicle. Some vehicles may require raising the car or removing the front subframe for access.
- Along with the oil pan, it is recommended to replace the oil filter, oil drain plug, and gasket.
- Always refer to the manufacturer's guidelines and torque specifications for your specific vehicle when replacing the oil pan.
- Oil pan replacement can be a messy job, so ensure you have the necessary tools and safety equipment before starting the repair.

Symptoms of a faulty oil pan
The oil pan, or oil sump, is where the oil in your car is stored. It is usually made from metal or hard plastic and is located under the car. The oil in the pan helps to lubricate the car's engine and keep its components cool. Over time, the oil pan can become damaged and may need to be replaced. Some common symptoms of a faulty oil pan include:
- Puddles of oil under the car: Small leaks can gradually get worse and lead to significant engine damage if left unattended.
- Leaks around the oil drain plug: The oil drain plug can become damaged over time and may begin to leak.
- Visible damage to the oil pan: The oil pan can be hit or dented when passing over low-lying parts of the road, leading to a fast leak or a steady drip.
- Engine noises: A cracked oil pan can cause the engine to make loud knocking or ticking noises due to insufficient oil.
- Warning lights: The oil pressure warning light on your dashboard may indicate a drop in oil levels, potentially due to a faulty oil pan.
- Decreased performance: Low oil levels or inadequate oil pressure can affect the vehicle's performance due to increased friction and the engine's inability to operate optimally.
- Streaks of oil behind the oil pan: If you notice streaks of oil underneath your vehicle, directly behind the oil pan, it could indicate a leak from the pan or the gasket.
- Oil coating on the undercarriage: An oil coating or greasy residue on the undercarriage of your vehicle may indicate a leaking oil pan.
- Low oil levels: If you notice that your engine's oil level is decreasing rapidly, it could be due to a leak in the oil pan.
