The Equinox uses a cartridge-style filter that sits on top of the engine

The Chevy Equinox oil filter is not a spin-on canister like older cars use. Instead, it's a cartridge filter housed in a plastic cap on the top or side of the engine, depending on your model year and engine size. The filter element itself looks like a accordion-folded paper cylinder, and you replace just that element — not the whole housing — during an oil change.

This design means you'll need a filter wrench to remove the cap, and you must buy the correct cartridge element for your specific engine. A 2015 Equinox with a 2.4-liter engine uses a different filter than a 2020 model with a 1.5-liter turbo, so checking your owner's manual or the parts counter is essential before you buy.

Key Takeaways

  • Equinox models use a cartridge-style filter in a plastic housing on top of the engine, not a traditional spin-on filter.
  • You need the correct filter element for your engine size and model year — a 2.4L, 1.5L turbo, and 2.0L turbo all use different filters.
  • A filter wrench is required to remove the plastic cap; you cannot unscrew it by hand.
  • Replacement takes about 10 to 15 minutes once you have the right part and tools.

Finding the correct filter for your Equinox

Start by locating your vehicle identification number (VIN), which appears on your registration, insurance card, or the dashboard on the driver's side. You can also find it on the door jamb sticker on the driver's side. Write down your VIN and your model year.

Call a Chevrolet dealership parts department or visit an auto parts store (AutoZone, O'Reilly, NAPA, or Advance Auto Parts) with your VIN. Tell them you need an oil filter for a Chevy Equinox. They will pull up your exact engine size and give you the correct cartridge filter element. The part number matters — buying the wrong one wastes money and leaves you with a filter that won't fit.

You can also check your owner's manual, which lists the correct filter part number in the maintenance section. If you no longer have the manual, search online for "[Your Year] Chevy Equinox owner's manual PDF" to find a free copy.

What you'll need to replace the filter yourself

Gather these items before you start: the correct cartridge filter element, a filter wrench (usually a 74mm or 86mm cap wrench, depending on your model), a new rubber O-ring gasket (often included with the filter, but buy a spare), a drain pan, clean rags or paper towels, and fresh engine oil.

A filter wrench is not optional — the plastic cap is tight and will crack if you try to force it by hand. You can buy a filter wrench at any auto parts store for $10 to $20. Some stores will loan you one free if you buy the filter from them, so ask before you pay.

You do not need to lift the vehicle for this job on most Equinox models, though you may need to remove the plastic engine cover to access the filter housing. Check your owner's manual or search YouTube for "[Your Year] Equinox oil filter replacement" to see whether your specific model requires this step.

Step-by-step replacement process

First, warm up the engine by running it for 30 seconds to a minute, then turn it off and wait five minutes. Warm oil drains faster and more completely than cold oil. Place your drain pan under the filter housing to catch any spilled oil.

Use the filter wrench to turn the plastic cap counterclockwise. It will loosen suddenly, so hold the wrench steady and turn slowly to avoid stripping the cap. Once it's loose enough, unscrew it by hand and set it aside. The old filter element will come out with the cap or stay in the housing — either way, remove it and dispose of it.

Look inside the housing for the old rubber O-ring gasket stuck to the cap or the housing itself. Peel it off and discard it. Wipe the inside of the housing clean with a rag. Install the new O-ring gasket on the plastic cap — it should sit in the groove on the underside of the cap. If the gasket is not included with your filter, you must buy one separately; do not reuse the old one.

Insert the new cartridge filter element into the housing, making sure it sits flat on the bottom. Screw the plastic cap back on by hand until the O-ring gasket touches the housing, then turn it an additional three-quarter turn with the filter wrench. Do not over-tighten — this will crush the gasket and cause a leak.

Start the engine and let it run for 30 seconds. Check under the filter cap for leaks. If you see oil dripping, turn off the engine, wait five minutes, and tighten the cap another quarter turn. Check again after running the engine. Once it's dry, you're done.

Common mistakes that cause leaks

The most frequent error is forgetting to install the new O-ring gasket or reusing the old one. The gasket is what seals the cap to the housing — without it or with a damaged one, oil will leak out when ready. Always replace the gasket every time you change the filter.

Over-tightening the cap is the second common mistake. The plastic housing can crack if you use the wrench to turn the cap more than about three-quarter turn after it touches the gasket. Hand-tight plus three-quarter turn is the correct amount. If you over-tighten and the cap cracks, you'll need to replace the entire housing, which costs $150 to $300 at a dealership.

Installing the filter element upside down or at an angle will prevent the cap from seating properly and cause leaks. Make sure the element sits flat on the bottom of the housing before you screw the cap back on.

When to replace your Equinox oil filter

Chevrolet recommends changing the oil filter every time you change the engine oil. For most Equinox models, that's every 7,500 miles or six months, whichever comes first. Some newer models with synthetic oil can go 10,000 miles between changes, but the filter should still be replaced at each oil change.

Check your owner's manual for your specific model's maintenance schedule. If you drive in severe conditions — frequent short trips, towing, dusty roads, or extreme temperatures — Chevrolet recommends more frequent changes, sometimes every 3,000 to 5,000 miles. Your manual will specify what counts as severe driving for your model year.

Frequently Asked Questions

Can I take my Equinox to a dealership or shop instead of doing it myself?

Yes. A Chevrolet dealership or independent shop can replace the filter in 15 to 30 minutes. Dealership prices typically range from $40 to $80 for labor plus the cost of the filter and oil. Independent shops are often less expensive. If you're uncomfortable working on your vehicle, this is a reasonable choice.

What if I can't find the filter housing on my Equinox?

The location varies by model year and engine size. On some Equinox models it's on top of the engine; on others it's on the side. Search YouTube for "[Your Year] Chevy Equinox oil filter location" with your specific model year, and you'll find a video showing exactly where it is. Your owner's manual also includes a diagram.

Do I need to change the oil at the same time as the filter?

No, you can replace just the filter without changing the oil. However, most people change both together because the engine is already warm and the drain pan is already out. Changing the filter alone takes about 10 minutes and costs $15 to $30 for the filter element and gasket.

What happens if I use the wrong filter element?

If the element is too large or shaped differently, the cap won't close properly and oil will leak out. If you install it and the cap doesn't seat flush, stop when ready, remove the element, and get the correct one. Running the engine with a leaking filter will drain your oil and damage the engine.

Can I reuse the plastic cap if it's not damaged?

Yes, the plastic cap is reusable. Only the cartridge filter element and the rubber O-ring gasket need to be replaced each time. If the cap cracks or the threads strip, you'll need to buy a new housing assembly from a dealership.
