How to Change Oil Filter: Tools and Tips for a Clean Swap

This is a step-by-step guide — easy to follow — on how you can change your car's oil filter all by yourself, saving money and gaining a sense of accomplishment. This guide equips you with the right tools and insider knowledge to ensure a smooth and mess-free process. By following these expert tips, you'll extend your vehicle's lifespan and keep its engine running at peak performance.

Regular Oil Filter Changes for Vehicle Maintenance

Regular oil filter changes are essential for keeping your car healthy. Engine oil breaks down over time and collects dirt and debris as it circulates. The oil filter traps these contaminants, preventing them from harming your engine's internal components. By changing the filter regularly, you ensure clean oil flows freely, reducing friction, improving engine performance, and extending its lifespan.

Oil Filter & Engine Health

The oil filter acts as your engine's internal bodyguard. Engine oil constantly circulates, picking up dirt, metal shavings, and other debris as it lubricates moving parts. Left unchecked, these contaminants can cause friction and wear. The oil filter traps these harmful particles before they can reach engine components, ensuring clean oil keeps your engine running smoothly and minimises long-term damage.

What is an Oil Filter?

An oil filter is a disposable component in your vehicle's engine that acts as a purifier for the motor oil. Engine oil constantly circulates throughout the engine, lubricating moving parts and picking up debris generated by engine wear.

The oil filter itself is a cylindrical cartridge containing filter media, often made of pleated paper. This media acts like a sieve, trapping the harmful contaminants within the filter while allowing clean oil to flow through. The clean oil then returns to the engine, preventing these abrasive particles from causing friction and wear on critical engine components. In essence, the oil filter keeps your engine's oil clean, promoting smooth operation and extending its lifespan.

Tools Required for Oil Filter Change

• Socket wrench set: You'll need a ratchet and a socket that fits your drain plug size.
• Oil filter wrench or pliers: Allow you to loosen and tighten the filter. There are two main types:
• Strap wrench: Uses a fabric strap to grip the filter by its outer diameter.
• Cap wrench: Designed to fit around the top of the oil filter.
• Drain pan: This pan will catch the used oil as it drains from your engine. Choose one with a large enough capacity to hold all of your used oil.
• Oil filter: Get the right oil filter for your specific car make and model. You can find this information in your owner's manual or by consulting a parts store employee.
• Rags: You'll need rags to clean up any spills and to wipe down the filter mounting area.

Optional Tools That Can Make the Process Easier

• Funnel: A funnel will help you pour the new oil into your engine without spilling it.
• Oil filter removal tool - optional: This tool can help you remove a stubborn oil filter without damaging it.
• Gloves: Wearing gloves will protect your hands from hot oil and dirt.
• Jack and jack stands - optional: If your car doesn't have enough ground clearance to reach the drain plug and oil filter easily, you'll need a jack and jack stand to lift it up.

Preparation Steps for Changing the Oil Filter

Before diving into the oil filter change, prioritise safety and ensure a clean work environment for a smooth experience. Here's what to consider:

Safety First

• Park on a level surface: Choose a flat and stable area to prevent your car from rolling.
• Engage the parking brake: This adds an extra layer of security to prevent accidental movement.
• Let the engine cool completely: Wait at least 30 minutes after running the engine.
• Consult your owner's manual: Refer to your car's manual for specific instructions and safety precautions related to your vehicle.

Preparing Your Work Area

• Gather your tools and supplies.
• Place a drain pan underneath the drain plug to catch all the used oil. Choose a pan with enough capacity to hold all the oil from your engine.
• Protect your workspace by placing a cardboard or a tarp under the work area to catch any drips or spills that might escape the drain pan.
• Wipe down the drain plug and surrounding area with a rag to remove any dirt or debris. This will prevent contaminants from entering the fresh oil during the change.

H2: Step-by-Step Guide to Changing an Oil Filter

Here's a step-by-step guide to help you through the process:

Draining the Oil

• Start by parking your car on a level surface, allowing the engine to cool down for a bit.
• Locate the oil drain plug underneath the vehicle and place a pan underneath it to catch the oil.
• Loosen the drain plug with a wrench and slowly remove it while keeping pressure on the plug. Let the oil drain completely into the pan.
• Once all the oil has drained out, reinstall the drain plug and tighten it securely.

Removing the Old Oil Filter

• Using an oil filter wrench or a specialised oil filter removal tool, loosen the old oil filter by turning it counterclockwise.
• Make sure the drain pan is positioned to catch any drips.

Preparing the New Oil Filter

 

• Lubricate the rubber gasket on the filter with a thin layer of fresh oil. This will help create a proper seal and make it easier to remove during the next oil change.

Installing the New Oil Filter

• Screw the new oil filter onto the threaded nipple on the engine block, turning it clockwise until it is hand-tight.

Adding New Oil and Checking for Leaks

• Refer to your vehicle owner's manual to determine the correct oil type and quantity needed.
• Use a funnel to pour the new oil into the engine.
• Once the oil is filled to the appropriate level, start the engine and let it run for a few minutes to circulate the new oil.
• Check around the oil filter and drain plug for any signs of leaks. If you notice any leaks, immediately turn off the engine and address the issue before driving the vehicle.

Avoid Mistakes During the Oil Filter Change

• Gather all your supplies beforehand.
• Warm up the engine, as warm oil flows easier, allowing you to drain more of the old oil and contaminants.
• Mind the drain plug: Don't overtighten the drain plug when you put it back on, as it can damage the threads.
• Replace the oil filter altogether. Using the wrong filter or not tightening it properly can cause leaks and potentially engine damage.
• Don't overfill the engine with new oil. Overfilling can put pressure on gaskets and seals.
• Dispose of the used oil and filter responsibly.

Regular Oil Filter Change

Regularly changing your oil filter is vital for keeping your car's engine healthy. The filter traps contaminants that circulate in the oil, preventing them from harming your engine components. This translates into a longer engine life, better fuel economy, and overall smoother performance. 

Following the guide above will ensure you avoid common pitfalls and complete the oil change process effectively yourself, saving you time and money in the long run. So, why not dive in and maintain your car like a pro?
