🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Secure the Hood

• 🧤 Put on the nitrile work gloves and safety glasses.
• Use the interior hood-release handle below the driver-side dashboard.
• Release the secondary latch at the front of the hood, then raise the hood.
• The hood supports itself with its lift struts; verify it remains fully open before proceeding.

Step 2: Locate the Air-Cleaner Housing

• 🔦 Use the LED flashlight to locate the black plastic air-cleaner housing at the front-left area of the engine compartment.
• Follow the large black intake tube from the engine toward the rectangular housing.
• The air filter sits between the housing’s upper cover and lower tray.

Step 3: Release the Housing Clips

• 🧤 Use your gloved fingers to release the metal retaining clips along the edge of the air-cleaner cover.
• Pull each clip outward until it disengages from the cover.
• Do not disconnect the intake hose or nearby electrical connector.
• No bolts are removed, so there is no torque specification for this step.

Step 4: Lift the Air-Cleaner Cover

• 🧤 Use both gloved hands to lift the clipped side of the cover slightly.
• Move the cover only far enough to access the filter, keeping the intake tube attached.
• Disengage the cover’s opposite-side locating tabs carefully if additional clearance is needed.
• Do not force the attached intake tube.

Step 5: Remove the Old Filter

• 🧤 Use your gloved fingers to lift the old engine air filter straight out.
• Notice how the filter sits in the lower housing before removing it completely.
• Keep the dirty side facing downward to avoid dropping debris into the housing.

Step 6: Clean and Inspect the Housing

• 🧽 Use the clean microfiber cloth to wipe loose dust from the lower housing.
• Do not push the cloth into the intake opening or leave fibers inside the housing.
• Use the LED flashlight to verify that no leaves, dirt, or packaging remain inside.
• Do not use compressed air because it can force debris farther into the intake.

Step 7: 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.
• Seat the filter’s sealing edge evenly inside the housing channel.
• Run a gloved finger around the perimeter to confirm the seal is flat and not folded.
• A pinched seal allows unfiltered air inside.

Step 8: Close the Housing

• 🧤 Use both gloved hands to engage the cover’s locating tabs first.
• Lower the cover evenly without shifting the filter.
• Use your gloved fingers to secure every metal retaining clip over the cover edge.
• Confirm there is no visible gap between the upper cover and lower housing.
• The clips are hand-fastened, so there is no torque specification.

Step 9: Final Inspection and Hood Closure

• 🔦 Use the LED flashlight to inspect the intake tube, housing clips, and nearby wiring.
• Use your gloved hands to gently check that the housing cover cannot lift.
• Lower the hood carefully, then press it closed from the front edge.

• 🔍 Recheck the filter during routine maintenance and replace it sooner in Sonīpat’s dusty driving conditions.
