Where to Find and Replace the Oil Filter on a 2018 Chevy Equinox

The 2018 Equinox uses a cartridge-style oil filter mounted on top of the engine

The 2018 Chevrolet Equinox has a cartridge oil filter — a cylindrical canister that screws into a housing cap on the top of the engine, not a spin-on filter that hangs from the side. This matters because you remove it differently than older Chevy models. The filter sits directly above the engine block, making it one of the easier filters to reach without lifting the vehicle.

All 2018 Equinox models — whether you have the 1.5L turbo, 2.0L turbo, or 2.4L engine — use the same cartridge design. The part number is GM 12640957, though aftermarket equivalents from Fram, Mobil 1, and Motorcraft are widely available and cost between $8 and $15.

Key Takeaways

The 2018 Equinox oil filter is a cartridge type that screws into a cap on top of the engine, not a spin-on filter underneath.
You will need an oil filter wrench (usually 74mm or 86mm depending on engine size) and a drain pan to catch old oil that spills when you remove the housing.
The filter housing cap comes off by hand or with a wrench, and the cartridge pulls straight out — no threading required.
Replacement takes 10 to 15 minutes once you have the right wrench, and you do not need to lift the vehicle.

Locate the filter housing on top of the engine

Open your hood and look toward the center-front of the engine. You will see a black cylindrical cap with a handle or knob on top — this is the oil filter housing. On the 1.5L turbo engine, it sits near the front-left side of the engine block. On the 2.0L and 2.4L engines, it is positioned more centrally. The cap is roughly 3 to 4 inches tall and has a diameter of about 3 inches.

If you cannot locate it when ready, trace the oil filler cap (where you pour new oil) — the filter housing is usually within 6 inches of it. You may see a small amount of dried oil residue around the base of the housing, which is normal.

Gather the correct tools and materials

You will need an oil filter wrench sized for your engine. The 1.5L turbo typically uses a 74mm wrench, while the 2.0L and 2.4L engines use an 86mm wrench. A universal adjustable filter wrench works if you do not know the exact size. You also need a drain pan (any shallow container will work), fresh oil that meets GM's specification for your engine (check your owner's manual), a new filter cartridge, and a clean rag or paper towels.

Do not attempt to remove the housing cap by hand if it is tight — you risk stripping the plastic threads or dropping it into the engine bay. The wrench gives you leverage and control. Most auto parts stores rent filter wrenches for $5 to $10 if you do not own one.

Remove the old filter cartridge

Place your drain pan under the filter housing to catch oil spillage. Use the filter wrench to turn the housing cap counterclockwise. It will loosen after a quarter turn or so. Once loose enough, you can unscrew it by hand — turn slowly to avoid spilling oil on the engine. Set the cap aside on a clean surface.

Inside the housing, you will see the old cartridge filter standing upright. Grab it by the top and pull it straight out. Some oil will drip from the cartridge and the housing cavity, so keep the drain pan positioned underneath. Wipe the inside of the housing cavity with a clean rag to remove any debris or old oil residue. Check the rubber seal on the underside of the cap — if it looks cracked or flattened, it should be replaced with the new filter kit (most cartridge filters come with a replacement seal).

Install the new filter and reseal the housing

Slide the new cartridge filter into the housing cavity, making sure it sits flat and fully inserted. The cartridge should not be forced — it will slide in smoothly if oriented correctly. If you have a replacement rubber seal in your filter kit, place it on the underside of the housing cap before reinstalling. Hand-tighten the cap back onto the housing, turning clockwise until the seal contacts the housing.

Once the seal makes contact, use the filter wrench to tighten the cap an additional three-quarter turn. Do not over-tighten — this can damage the plastic threads or crush the seal. The cap should be snug but not cranked down with force. Wipe away any spilled oil from the engine block and housing area with your rag.

Refill the engine with new oil and check the level

Locate the oil filler cap on top of the engine (it usually has an oil can symbol on it) and unscrew it. Pour in the amount of new oil specified in your owner's manual — typically 4.5 to 5.5 quarts depending on engine size and whether you are doing a full oil change or just replacing the filter. Replace the filler cap and twist it clockwise until snug.

Wait 2 to 3 minutes for the new oil to settle into the pan and filter cavity. Then start the engine and let it run for 30 seconds to circulate the new oil. Turn off the engine and wait another 2 to 3 minutes. Pull out the dipstick, wipe it clean, reinsert it fully, and pull it out again to check the level. The oil should be between the minimum and maximum marks. Add a small amount more if needed, then reinstall the dipstick and filler cap.

Dispose of the old filter and used oil properly

Do not throw the old cartridge filter in the trash. Most auto parts stores that sell filters — including AutoZone, O'Reilly, and Advance Auto Parts — will take used filters and oil for free. Some Chevrolet dealerships also accept them. Drain as much oil as possible from the old cartridge into your drain pan before taking it in.

If you drained the oil pan as part of a full oil change, that used oil also needs to go to a recycling center or auto parts store. Never pour it down a drain or into the ground. Many municipalities have hazardous waste collection days where you can drop off used oil at no cost.

Frequently Asked Questions

Do I need to replace the rubber seal every time I change the filter?

Most cartridge filter kits include a replacement seal. It is a good idea to use it, especially if the old seal looks compressed or cracked. However, if the seal still looks pliable and the housing cap was not over-tightened, you can reuse it. Inspect it before deciding.

What happens if I over-tighten the housing cap?

Over-tightening can crack the plastic threads on the housing or crush the rubber seal, causing oil to leak around the cap. If you notice a drip after starting the engine, turn off the engine, let it cool, and loosen the cap slightly — usually a quarter turn back is enough to stop the leak without compromising the seal.

Can I use any oil filter, or does it have to be GM?

You do not need a GM-branded filter. Any cartridge filter designed for the 2018 Equinox will work, including Fram, Mobil 1, Motorcraft, and store brands. Check the part number or cross-reference your engine size and year at an auto parts store to confirm compatibility.

How often should I change the oil filter on a 2018 Equinox?

Chevrolet recommends changing the oil and filter every 7,500 miles or every 6 months, whichever comes first. If you drive mostly short distances or in dusty conditions, more frequent changes may extend engine life. Check your owner's manual for the specific interval for your driving habits.

Is it normal for oil to drip from the housing after I remove the cap?

Yes. The housing cavity holds oil, and some will spill when you unscrew the cap. This is why you place a drain pan underneath. If oil continues to drip from the cap area after you reinstall it and run the engine, the seal may not be seated correctly — remove the cap, check the seal, and reinstall it.
