Owners of other General Motors vehicles from Chevrolet, GMC, Cadillac, Buick and Holden such as the Trax, Equinox, Traverse, Blazer, Tahoe, Suburban, Sonic, Cruze, Trailblazer, Spark, Malibu, Impala, Volt, Bolt, Corvette, Camaro, Silverado, Express, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, Canyon, Sierra, Terrain, Acadia, Yukon, XT4, XT5, XT6, Escalade, CT5, CTS, XTS, CT6, ATS, Astra and Commodore may also find these DIY instructions to be helpful.

A few compatible replacement air filters for the LFX or LGZ 3.6L V6 engines with their compatible replacement part numbers include the following: ACDelco A3195C, K&N 33-5030, EcoGard XA10411, AEM 28-50030 and Purolator A48171.

The only tool needed to access and replace the filter is a standard Phillips head screwdriver or a flat head screwdriver.

The first two steps are to open the hood and then move to the left (passenger) side of the engine bay.

The engine air box is located just in front of the coolant reservoir bottle and behind the passenger side headlight housing.

The air box cover is held in place by four screws.

Loosen the four screws by turning them in the counterclockwise direction with either a Phillips head screwdriver or you could also use a flat head screwdriver.

The screws are "captured" so they will remain attached to the air box cover.

Slide the cover towards the right to release the three plastic tabs on the left side of the cover from their slots on 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 dirt, dust, sand, insects, leaves, twigs, pollen, soot and other debris, it should be replaced with a new element.

I recommend buying the OEM (original equipment manufacturer) engine air filter which is part number ACDelco A3195C.

If the old filter is relatively clean, just tap out the large debris.

Check the bottom half of the air box and clean out any sand or other debris.

Lower the new air filter into the bottom half of the housing with the pleats facing down and the rubber gasket facing up towards you.

Slide the tabs into their slots while lowering the air box cover.

Tighten the four screws by turning them in the clockwise direction with the Phillips head screwdriver or a flat head screwdriver.

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

The two halves of the air box should be flush together with no part of the new filter visible at the edges.

Be sure to write down the filter change in your truck's service records.

(The service interval specification for the engine air filter is every 45,000 miles according to the maintenance schedule in the owner's manual.)
