2016 Acadia Engine Air Box
Loose Metal Hose Clamp
Six Air Box Screws
This automotive maintenance tutorial was specifically written to assist owners of the first generation (2009, 2010, 2011, 2012, 2013, 2014, 2015 & 2016) GMC Acadia equipped with the 3.6 liter LLT V6 motor in cleaning or changing the engine air filter element.

Owners of other General Motors vehicles such as the Buick Verano, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra 1500, Terrain, Yukon, Denali, Savana, Spark, Sonic, Cruze, Malibu, Impala, Volt, Camaro, Corvette, SS, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado and Express may also find these DIY instructions to be helpful.

The tools needed to complete this procedure include a flathead screwdriver and a Torx T25 star bit screwdriver.

A few compatible replacement filters with their part numbers are as follows: Fram CA10110, K&N 33-2394, Wix 49634, ACDelco A3083C, Purolator A66313, Hastings AF1377, AEM 28-20394, GKI AF101110 and Pentius PAB10110.

Loosen Counterclockwise
Slide Back Red Lock Tab
Pull Off Electrical Connector
The first two steps are to open the hood and then move to the right side of the engine bay.

The engine air box is located on the right side in between the brake fluid reservoir and the windshield washer fluid filler tube.

There are six screws that hold the top cover of the engine air box in place.

Loosen the metal hose clamp on the air intake hose by turning the screw counterclockwise with a flathead screwdriver.

Then slide back the red locking tab on the electrical connector for the IAT / AIT (air intake temperature) sensor before pressing the release tab and sliding it straight out of its socket.

2nd Screw
3rd Screw
4th Screw
Remove the 5 visible screws by turning them counterclockwise with a Torx T-25 star bit screwdriver.
Remove 5th Screw
6th Screw Location
Remove Oil Filler Cap
Set the 5 screws aside in a safe place.

To access the sixth screw, you'll need to remove the black plastic engine cover and the plastic air intake tube.

Spin off the engine oil filler cap by turning it 1/4 turn counterclockwise. Set the oil filler cap aside in a safe place.

Pull Off Plastic Engine Cover
Loosen Air Intake Clamp
Pull Off Air Intake Hose
Gently pull the plastic engine cover straight off and set it aside in a safe place.

Loosen the hose clamp on the plastic air intake tube by turning it counterclockwise with the flathead screwdriver.

Disconnect Air Box Hose
Sixth Screw Accessible
Loosen Counterclockwise
Remove the air intake hose and set it aside in a safe place.

Now you can finally access the 6th and final air box cover screw.

Loosen the screw by turning it counterclockwise with the Torx T25 screwdriver.


6 Torx T25 Screws Removed
Pull Off Air Box Cover
Pull Out Old Engine Filter
Set the sixth screw aside with the other 5 screws.

Lift the engine air box cover off the lower half and set it aside in a safe place.

Clean Out Lower Half
Inspect Both Sides
Clean With Vacuum
If your vacuum cleaner has a crevice attachment, clean out any sand, dust, dirt, pollen, debris, insects, leaves, or twigs from the bottom half of the air box.

Inspect both sides of the old filter.

If the old filter is dark grey or black and clogged with soot, dust, dirt, insects, hair and other debris, it should be replaced with a new element.

I recommend buying either the GM OEM ACDelco A3083C filter or the Fram CA10110 filter since they both have excellent reviews on Amazon.

If you'd prefer to have a re-usable filter, go with the K&N 33-2394 filter which will need to be washed and re-oiled every 50,000 miles.

If the old filter is relatively clean, just tap out the large debris and remove any fine dust with a vacuum cleaner.

Install New Air Filter
Line Up Air Box Cover
Lower Air Box Cover
Lower the new air filter in to the bottom part of the air box.

The filter's shape will only allow it to be installed in the correct orientation.

Carefully lower the air box cover on to the bottom half of the box.

Make sure that the two halves of the air box are flush together with no parts of the new filter visible.

Replace the sixth screw that will be blocked by the air intake assembly. Turn it clockwise with the Torx T25 screwdriver.

Push On Air Intake Hose
Slide On Engine Air Intake
Re-Insert Rubber Hose
Push the rubber air intake hose on to the air box.

Slide the black plastic air intake tube on to the silver metal engine air intake.

Re-insert the smaller rubber hose on the front of the air intake tube in to the larger hose attached to the engine.

Push In Sensor Connector
Slide In Red Locking Tab
Tighten T25 Screws
Push the air intake temperature sensor electrical connector straight in to its socket.

Slide in the red lock tab to secure the plug in place.

Tighten Clockwise
Push On Plastic Engine Cover
Replace Oil Filler Cap
Tighten the other 5 screws in the clockwise direction until they are snug.

Try to avoid over tightening the screws to prevent from cracking the plastic air box assembly.

Push the plastic engine cover back in to place and spin on the oil filler cap in the clockwise direction.

Be sure to record the engine air filter change in your SUV's service records.
