Hey guys! Changing the oil in your 2007 Scion tC is a simple maintenance task that can save you money and keep your ride running smoothly. This guide provides a detailed, step-by-step walkthrough to help you confidently perform this service at home. Let's dive in!

Why Change Your Oil?

Before we get started, let's quickly cover why regular oil changes are crucial. Your engine oil lubricates all the moving parts within the engine, reducing friction and wear. Over time, oil breaks down, becomes contaminated with dirt and debris, and loses its ability to protect your engine effectively. Neglecting oil changes can lead to serious engine damage, reduced performance, and costly repairs. Think of it like this: your engine is a complex machine, and oil is its lifeblood. Keeping that lifeblood clean and fresh is essential for longevity and optimal performance.

Regular oil changes ensure:

• Reduced engine wear
• Improved fuel economy
• Optimal engine performance
• Extended engine life

What You'll Need

To perform an oil change on your 2007 Scion tC, gather the following items:

• New Oil: The 2007 Scion tC typically requires approximately 4.7 quarts of SAE 5W-30 engine oil. Always refer to your owner's manual to confirm the exact specification and quantity. Using the correct oil is crucial for proper engine lubrication and performance. Different oils have different viscosities and additives, and using the wrong type can lead to engine damage.
• New Oil Filter: A new oil filter is essential to remove contaminants from the oil. Use the correct oil filter for your 2007 Scion tC; a Purolator PL14477, Mobil M1-103, or Wix 51394 are common choices. Check online retailer websites to confirm compatibility with your specific vehicle model and year. The oil filter is responsible for trapping dirt, debris, and other contaminants that can damage your engine. Replacing it with each oil change ensures that your new oil stays clean and effective.
• Wrench for the Oil Filter: An oil filter wrench is needed to remove the old oil filter. These wrenches come in various styles, so choose one that fits your filter and is comfortable to use. Some common types include cap-type wrenches, band-type wrenches, and adjustable pliers-style wrenches. Make sure the wrench you choose provides a secure grip on the filter to prevent slippage.
• Socket Wrench and Socket (usually 14mm or 15mm): You'll need a socket wrench and the correct size socket to remove the oil drain plug. Refer to your vehicle's repair manual or online resources to verify the correct socket size for your specific model year. The drain plug is located on the bottom of the oil pan and needs to be loosened to drain the old oil.
• Drain Pan: A drain pan is necessary to catch the old oil as it drains from the engine. Choose a pan with sufficient capacity to hold all the oil and a wide opening to prevent spills. Position the drain pan carefully under the drain plug before removing it to avoid making a mess.
• Funnel: A funnel will help you pour the new oil into the engine without spilling. Using a funnel makes the process cleaner and easier, especially in tight engine compartments. Make sure the funnel is clean and dry before using it to avoid contaminating the new oil.
• Gloves: Wear gloves to protect your hands from the dirty oil. Oil can be messy and contain harmful chemicals, so wearing gloves is essential for safety and cleanliness. Choose gloves that are resistant to oil and provide a good grip.
• Rags or Shop Towels: Have plenty of rags or shop towels on hand to clean up any spills or drips. These are essential for keeping your work area clean and preventing oil from spreading to other parts of the vehicle.
• Jack and Jack Stands (or Ramps): You'll need a jack and jack stands (or ramps) to safely lift the vehicle and access the oil drain plug. Always use jack stands to support the vehicle after lifting it with a jack. Never work under a vehicle supported only by a jack, as this is extremely dangerous. Ramps are a convenient alternative to a jack and jack stands, but make sure they are rated to support the weight of your vehicle.
• Wheel Chocks: Use wheel chocks to prevent the vehicle from rolling while it's lifted. Place the chocks behind the wheels that are opposite the ones you're lifting. This adds an extra layer of safety to the process.

Step-by-Step Instructions

Now that you have all the necessary tools and materials, let's get started with the oil change.

Step 1: Prepare the Vehicle

1. Warm up the engine: Run the engine for a few minutes to warm the oil. Warm oil flows more easily, allowing it to drain more completely. However, be careful not to overheat the engine, as hot oil can cause burns. A few minutes of idling is usually sufficient.
2. Secure the vehicle: Park the car on a level surface, engage the parking brake, and use wheel chocks behind the rear wheels. This ensures that the vehicle will not move while you are working on it.
3. Lift the vehicle: Use a jack to lift the front of the car and securely place jack stands under the frame rails. Alternatively, drive the car onto ramps. Ensure the vehicle is stable before proceeding. Safety is paramount, so double-check that the jack stands are properly positioned and the vehicle is securely supported.

Step 2: Drain the Old Oil

1. Locate the oil drain plug: The oil drain plug is located on the bottom of the oil pan. Consult your vehicle's repair manual if you're unsure of its exact location. It's usually a large bolt with a hexagonal head.
2. Position the drain pan: Place the drain pan directly under the oil drain plug to catch the old oil. Make sure the pan is large enough to hold all the oil and is positioned to prevent spills.
3. Loosen the drain plug: Use the socket wrench and the correct size socket to loosen the drain plug. Be careful not to strip the plug by applying too much force. Once the plug is loose, you can usually unscrew it by hand.
4. Remove the drain plug: Carefully remove the drain plug, allowing the old oil to drain into the pan. Be prepared for a steady stream of oil, and avoid touching the hot oil with your bare hands. Allow the oil to drain completely, which may take 15-20 minutes.
5. Inspect the drain plug: Check the drain plug for any damage or wear. If the threads are damaged, replace the plug with a new one. Also, inspect the drain plug gasket or sealing washer and replace it if necessary. A damaged or worn gasket can cause oil leaks.

Step 3: Replace the Oil Filter

1. Locate the oil filter: The oil filter is usually located near the engine block. Consult your vehicle's repair manual if you're unsure of its exact location. It's a cylindrical canister that's screwed onto the engine.
2. Position the drain pan: Place the drain pan under the oil filter to catch any oil that spills when you remove the filter. Oil filters usually contain a small amount of oil, so be prepared for some spillage.
3. Loosen the oil filter: Use the oil filter wrench to loosen the old oil filter. You may need to apply some force to break it free. Be careful not to damage the surrounding components.
4. Remove the oil filter: Unscrew the oil filter by hand. Be prepared for some oil to spill as you remove it. Dispose of the old oil filter properly according to local regulations.
5. Prepare the new oil filter: Lightly lubricate the rubber gasket on the new oil filter with fresh engine oil. This will help create a good seal and prevent leaks. Also, fill the new oil filter with a small amount of fresh oil. This will help prime the oil system and ensure that the engine receives oil quickly after the oil change.
6. Install the new oil filter: Screw the new oil filter onto the engine by hand until the gasket makes contact with the engine block. Then, tighten it an additional ¾ turn, or according to the instructions on the filter. Do not overtighten the oil filter, as this can damage the gasket and cause leaks.

Step 4: Reinstall the Drain Plug

1. Clean the drain plug: Clean the drain plug and the surrounding area on the oil pan. This will help ensure a good seal and prevent leaks.
2. Install the drain plug: Reinstall the drain plug, making sure the gasket or sealing washer is in place. Tighten the drain plug to the correct torque specification, as specified in your vehicle's repair manual. Overtightening the drain plug can damage the oil pan, while undertightening it can cause leaks.

Step 5: Add New Oil

1. Locate the oil filler cap: The oil filler cap is usually located on the top of the engine. Consult your vehicle's repair manual if you're unsure of its exact location. It's usually marked with an oil can symbol.
2. Remove the oil filler cap: Remove the oil filler cap and insert the funnel into the opening.
3. Add the new oil: Pour the correct amount of new oil into the engine through the funnel. Refer to your owner's manual for the exact quantity. Start by adding slightly less than the recommended amount, as you can always add more later. For the 2007 Scion tC, this is typically around 4.7 quarts.
4. Check the oil level: After adding the oil, wait a few minutes for it to settle. Then, check the oil level using the dipstick. The dipstick is usually located near the oil filler cap. Remove the dipstick, wipe it clean, reinsert it fully, and then remove it again to check the oil level. The oil level should be between the minimum and maximum marks on the dipstick. Add more oil if necessary to reach the correct level. Be careful not to overfill the engine, as this can damage the engine.

Step 6: Final Steps

1. Replace the oil filler cap: Replace the oil filler cap and tighten it securely.
2. Start the engine: Start the engine and let it run for a few minutes. Check for any leaks around the oil drain plug and oil filter. If you see any leaks, tighten the connections until they stop.
3. Check the oil level again: After running the engine, check the oil level again and add more oil if necessary. The oil level may drop slightly after the engine has been running.
4. Reset the oil maintenance light: Reset the oil maintenance light according to the instructions in your owner's manual. This will remind you when the next oil change is due.
5. Dispose of the old oil properly: Take the old oil to a recycling center or auto parts store for proper disposal. Do not pour it down the drain or into the environment. Many auto parts stores will accept used oil for free recycling.
