🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Secure the Hood

• Use your gloved hand to pull the hood-release handle below the driver’s side of the dashboard.
• Release the secondary latch beneath the front edge of the hood.
• Raise the hood and verify that its support mechanism holds it securely.

Step 2: Locate the Air-Cleaner Housing

• Use the LED inspection flashlight to locate the black air-cleaner housing connected to the large ribbed intake hose.
• Identify the metal retaining clips along the edge of the housing cover.
• A retaining clip is a spring-loaded latch that holds the cover closed.

Step 3: Release the Housing Cover

• Use your gloved fingers to pull each metal retaining clip outward until it releases.
• Lift the clip-side of the cover slightly, then disengage the cover’s locating tabs from the opposite side.
• Do not pull hard on the intake hose or nearby wiring.
• Note the cover position before lifting it.

Step 4: Remove the Old Filter

• Use your gloved hand to lift the old engine air filter straight out of the lower housing.
• Observe how the filter’s rubber sealing edge sits in the housing before removing it completely.
• Keep dirt from falling into the clean-air opening leading toward the engine.

Step 5: Clean and Inspect the Housing

• Use the LED inspection flashlight to inspect the bottom of the housing for leaves, sand, or insects.
• Use the shop vacuum with crevice attachment to remove loose debris without touching the intake opening.
• Use a clean microfiber cloth to wipe the filter-sealing ledge.
• Do not use compressed air because it can push debris 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 perimeter seal lies flat and fully inside its channel.
• Do not force, bend, trim, or oil the replacement filter.
• A raised seal will cause an air leak.

Step 7: Close the Housing

• Use your gloved hands to engage the cover’s locating tabs first.
• Lower the opposite side of the cover while checking that no section of the filter seal is pinched.
• Press the cover down gently and snap each metal retaining clip fully into place.
• No fastener torque specification applies because the housing uses hand-operated clips.

Step 8: Perform a Final Inspection

• Use the LED inspection flashlight to check that the housing seam is even on every side.
• Use your gloved hand to gently check that the intake hose and nearby electrical connectors remain secure.
• Remove the microfiber cloth, shop vacuum, flashlight, and all packaging from the engine compartment.
• Lower the hood and press it closed securely.

✅ After Repair

• 🚨 Confirm that no warning light appears on the instrument panel.
• 🔎 If the engine runs roughly, switch it off and recheck the filter seal, housing tabs, clips, intake hose, and electrical connectors.
• 🗓️ Inspect the filter during routine service and replace it sooner when driving in Sonīpat’s dusty conditions.
