🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the Air-Cleaner Housing

• Use the LED flashlight to locate the large black plastic air-cleaner housing near the front corner of the engine compartment.
• Follow the wide intake hose from the engine to the housing if you are unsure.

Step 2: Release the Housing Clips

• Put on the nitrile mechanic’s gloves and release the metal retaining clips around the edge of the housing cover by hand.
• A retaining clip is a spring-loaded latch that holds the cover tightly against the lower housing.
• Support each clip while releasing it so it does not snap against the plastic.

Step 3: Lift and Disengage the Cover

• Use your gloved hands to lift the clipped edge of the cover slightly.
• Move the cover enough to disengage its locating tabs from the opposite side. Do not pull hard on the attached intake hose.
• Do not disconnect sensors or intake hoses.

Step 4: Remove the Old Filter

• Use your gloved hands to lift the old engine air filter straight out.
• Use the LED flashlight to inspect the lower housing for leaves, sand, or other debris.
• Keep debris from falling into the clean-air outlet leading toward the engine.

Step 5: Clean the Housing

• Use the microfiber cleaning cloth to wipe loose dust from the lower housing and its sealing edge.
• Do not push the cloth into the intake opening or use compressed air toward the engine.

Step 6: Install the New Filter

• Use your gloved hands to place the new filter into the lower housing in the same orientation as the old filter.
• Make sure the filter’s rubber sealing edge sits flat and evenly inside the housing.
• Do not force, bend, oil, or trim the filter.

Step 7: Close the Housing

• Use your gloved hands to engage the cover’s locating tabs first.
• Lower the opposite edge while checking that the filter seal remains inside the housing.
• Press the cover fully into position and fasten every retaining clip by hand.
• No fastener torque specification applies because the filter housing uses hand-operated clips.

Step 8: Perform a Final Inspection

• Use the LED flashlight to inspect the entire housing seam.
• Confirm there are no gaps and no section of the filter seal is pinched outside the housing.
• Check that the intake hose and nearby electrical connectors were not disturbed.
