How to Change Your Toyota Highlander's Oil Filter
What You'll Need Before You Start
Changing your Highlander's oil filter is a task you can do at home with basic tools. Before you begin, gather these items:
- A new oil filter (the correct size for your model year)
- An oil filter wrench
- A drain pan or container
- Jack and jack stands (if you need to lift the vehicle)
- Ramps (optional, instead of jack stands)
- Clean rags or paper towels
- Safety glasses
- Work gloves
Check your owner's manual to find the exact filter size and location for your specific model year. Having everything ready before you start makes the job go more smoothly and keeps you safe while working on your vehicle.
Most auto parts stores can help you find the right filter if you tell them your Highlander's year, make, and model. They can also show you what an oil filter wrench looks like if you've never used one before. Taking a few minutes to prepare properly means you won't have to stop midway through the job to hunt for a tool.
Locate Your Oil Filter
On most Highlanders, the oil filter sits on the side of the engine. The exact location can vary depending on your model year and engine type. You may need to raise the vehicle slightly to reach it comfortably. If you do lift the vehicle, always use jack stands for safety—never work under a vehicle supported only by a jack. Ramps are another safe option if you prefer not to use jack stands.
Consult your manual if you're unsure where the filter is located on your model. The manual will have a diagram showing you exactly where to look. Some Highlanders have the filter in an easy-to-reach spot, while others require you to remove a plastic cover or work around other engine components. Taking time to find it first prevents frustration later.
Drain Old Oil (Optional But Recommended)
Before removing the filter, you can drain the old oil to reduce mess and make the job cleaner. Locate the drain plug underneath the engine, place your drain pan below it, and unscrew the plug by hand. Let the oil drain completely—this may take several minutes. Wipe the plug clean and set it aside on a clean rag.
Draining the old oil is not strictly necessary when changing just the filter, but many people do it anyway. It helps you see if there are any problems with the drain plug, and it keeps old oil from spilling when you remove the filter. If you skip this step, just be extra careful when removing the filter, as some oil will still drip out.
Remove the Old Filter
Position your drain pan under the oil filter to catch any remaining oil. Use your oil filter wrench to loosen the filter by turning it counterclockwise. Once loose, carefully unscrew it by hand and let any oil drip into the pan. This step is where most of the mess happens, so don't rush it.
Wipe the filter mounting surface on the engine with a clean rag to remove any dirt or old rubber. This is important because debris left behind can prevent the new filter from sealing correctly. Take your time here—a clean surface means a better seal and fewer leaks later on.
Install the New Filter
Before installing the new filter, apply a thin layer of new oil to the rubber gasket on top of the filter. This helps create a proper seal and makes it easier to remove the filter next time. You only need a light coating—not a thick layer.
Screw the new filter onto the mounting surface by hand. Tighten it until the gasket contacts the engine, then turn it an additional three-quarters of a turn. Do not over-tighten—hand-tight is correct. Over-tightening can damage the filter or make it hard to remove later. If you tighten it too much, you may have trouble getting it off during your next oil change.
Refill Your Oil
If you drained the old oil, locate the oil filler cap on top of the engine and remove it. Pour in the recommended amount of new oil for your model year (check your manual). Replace the cap when done. The amount of oil your Highlander needs depends on whether you also changed the oil or just the filter.
Start your engine and let it run for a few seconds, then turn it off. Wait a minute, then check the oil level on your dipstick or digital gauge. Add more oil if needed. This check ensures you have the right amount of oil in your engine, which is important for keeping it running well.
Dispose of Old Oil and Filter Properly
Wipe up any spilled oil and dispose of the old filter and oil properly at a recycling center or auto parts store. Many retailers will take used oil and filters at no cost. Never pour old oil down the drain or throw it in the trash, as it harms the environment.
Some auto parts stores offer rewards or discounts if you bring in old oil and filters. Call ahead to ask about their recycling program. Proper disposal is easy and often costs nothing, making it a simple way to protect the environment.
Key Takeaways
Changing your Highlander's oil filter is a straightforward job that saves you money compared to having a shop do it. The most important steps are gathering the right tools beforehand, finding the filter location in your manual, and being careful not to over-tighten the new filter. Always use jack stands if you lift your vehicle, and take time to clean the mounting surface before installing the new filter. Finally, dispose of the old oil and filter at a proper recycling location. Check your manual for how often you should change your filter—most Highlanders need a new one every 10,000 miles or so, though this can vary by model year and driving conditions.
Frequently Asked Questions
How do I know what size oil filter my Highlander needs?
The best way to find the right filter size is to check your owner's manual. You can also visit an auto parts store and tell them your vehicle's year, make, and model—they can look it up for you. Never guess on the filter size, as using the wrong one can cause leaks or engine damage.
What should I do if oil leaks from the new filter after I install it?
A small drip or two is normal for the first few minutes after installation. However, if oil continues to leak, the filter may not be tight enough or the gasket may not be seated correctly. Turn off the engine, let it cool, and check that the filter is hand-tight. If it's already tight and still leaking, remove it and inspect the mounting surface for dirt or damage. Clean it thoroughly and try again with a new filter.
Can I change just the oil filter without changing the oil?
Yes, you can change just the filter without changing the oil. Many people do this between full oil changes. However, if your oil is dark or dirty, it's a good idea to change both the oil and filter at the same time. Check your manual for the recommended maintenance schedule for your specific Highlander model.
How tight should the new oil filter be?
Hand-tight is the correct tightness for an oil filter. Screw it on until the rubber gasket touches the engine, then turn it an additional three-quarters of a turn. Do not use a wrench to tighten it further. Over-tightening can damage the filter and make it difficult to remove during your next change.
