Follow these steps carefully
Park level, switch off, and open the hood. The same housing and filter serve all three engines in this generation (2.0L turbo, 2.5L four, and the 3.6L V6), so the procedure is identical whichever Acadia you drive.
Turn them gently; they thread into plastic and strip if muscled. Drop each screw into a small tray or cup as you go — five identical screws scattered across the engine bay is how a ten-minute job becomes an hour.
Lift the air cleaner cover up and away from the engine, following the manual's direction. You don't need to haul the whole cover out of the bay: owners find it pops up just enough to slide the old filter out and the new one in, which is easier than wrestling the cover past the ducting. Keep it tilted so the underside faces up and doesn't pick up grit.
Slide the old filter out and note how it sat — the sealing flange has a correct orientation. Hold it up to the light: if little light passes through the pleats or it's gray with embedded debris, it was due.
Wipe the inside of the lower housing with a damp cloth and clear any leaves or sand from the corners. The owner's manual cautions that if the air cleaner is off, dirt can easily get into the engine, so work carefully and don't set the filter or tools down inside the open housing. Check the cover's seal and the housing rim for cracks while you're in there.
I've learned this one the hard way — the owner's manual cautions that if the air cleaner is off, dirt can easily get into the engine, so work carefully and don't set the filter or tools down inside the open housing.
Set the new filter into the lower housing in the original orientation, pressing the flange down flat all the way around. Confirm it sits fully in the tray and doesn't rock — the filter must seal against the housing or dirty air bypasses it.
Start the engine and let it idle. The manual notes the air cleaner also helps stop flames if the engine backfires, so never drive with it off; a properly sealed job idles smoothly with no whistle or hiss from the passenger side.

Test your repair before closing everything up. If something doesn't work right, double-check your steps.
