🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open and Secure the Hood

• Wear the safety glasses and nitrile work gloves.
• Pull the hood-release lever inside the cabin, release the secondary latch under the hood, and raise the hood.
• Secure the hood with its support rod before working underneath it.

Step 2: Locate the Air-Cleaner Housing

• Use the LED work light to find the black plastic air-cleaner housing connected to the large engine intake hose.
• Identify the metal retaining clips along the edge of the housing cover. These clips hold the upper and lower housing sections together.

Step 3: Release the Housing Cover

• Use your gloved fingers to pull each metal retaining clip outward until it releases.
• Lift the clipped edge of the housing cover slightly, then disengage the locating tabs on the opposite edge.
• Do not stretch the intake hose or pull on the airflow-sensor wiring attached to the cover.
• No bolts are removed, so there is no torque specification for this step.

Step 4: Remove the Old Filter

• Use your gloved fingers to lift the old engine air filter straight out of the lower housing.
• Notice how the filter’s rubber sealing edge sits in the housing before removing it completely.
• Keep the clean-air opening covered by the raised housing lid while inspecting the filter area.

Step 5: Clean and Inspect the Housing

• Use the LED work light to check the lower housing for leaves, sand, or insects.
• Use the microfiber cleaning cloth to wipe loose debris from the housing without pushing dirt into the intake opening.
• Inspect the housing and intake hose for cracks or loose connections.
• Never blow debris toward the engine intake.

Step 6: Install the New Filter

• Use clean, gloved hands to place the new engine air filter into the lower housing in the same orientation as the old filter.
• Make sure the filter’s rubber sealing edge lies flat and fully inside the housing channel.
• Do not force, bend, oil, or trim the filter.
• A pinched seal can let dust bypass the filter.

Step 7: Close the Housing

• Use your gloved hands to engage the housing cover’s locating tabs first.
• Lower the opposite edge and verify that the cover sits evenly without trapping the filter seal.
• Press each metal retaining clip into place by hand until it locks securely.
• The clips are hand-secured; no torque specification applies.

Step 8: Perform a Final Inspection

• Use the LED work light to confirm that the housing has no visible gaps around its edge.
• Check that the intake hose and airflow-sensor electrical connector remain secure.
• Remove the LED work light and microfiber cleaning cloth from the engine compartment, then lower and latch the hood.

• 📅 Inspect the filter during routine servicing and replace it sooner when driving in Panipat’s dusty conditions.
• 🧰 No scan-tool reset or engine calibration is required.
