Step 1: Check Your Service Manual

  • Every vehicle has unique installation requirements—verify torque specs and proper procedures.
  • If you're unfamiliar with catalytic converter installation, consult a qualified technician to avoid mistakes.

Step 2: Diagnose & Fix Any Issues Before Installation

  • A failed catalytic converter is often caused by underlying problems, such as:
    ✅ Faulty oxygen sensors
    ✅ Engine misfires
    ✅ Fuel mixture issues (too rich or too lean)
    ✅ Oil or coolant leaks into the exhaust
  • Fixing these issues is crucial—otherwise, your new converter may fail prematurely!

Step 3: Avoid Incorrect Sealants

🚨 DO NOT use silicone-based or Teflon sealants!

  • These materials can outgas at high temperatures and damage oxygen sensors.
  • Use manufacturer-approved gaskets for proper sealing.

Step 4: Install the Catalytic Converter Properly

  • Ensure proper alignment with the exhaust system—misalignment can lead to leaks and rattling.
  • Secure all bolts, clamps, and brackets evenly and to the correct torque specs.
  • Double-check for exhaust leaks before moving on to the next step.

Step 5: Break-In Process (MUST-DO!)

🚗 A proper break-in cycle is required to activate the converter’s internal materials and prevent failure.

  • 📌 Step 1: Start Your Engine
    DO NOT press the accelerator—let the engine start naturally.
  • 📌 Step 2: Idle the Engine
    Let the engine warm up for 5 minutes at idle speed.
  • 📌 Step 3: Increase Engine Speed to 2,500 RPM
    Slowly press the accelerator until you reach 2,500 RPM.Hold it steady for 2 minutes to stabilize the catalytic materials inside.
  • 📌 Step 4: Let the Engine Cool Down
    Turn off the engine and allow the system to cool naturally before driving.
  • 📌 Step 5: Perform a Test Drive
    Drive normally for 30 minutes, avoiding:
    ❌ Hard acceleration
    ❌ Excessive idling
    ❌ Sudden stops

    🚨 Skipping this process may result in premature failure of your new converter!

Step 6: Reset the ECM & Drive Cycle

  • Your vehicle’s Engine Control Module (ECM) needs to recognize the new converter.
  • Follow your vehicle manufacturer's guidelines for a drive cycle to reset engine codes.

✅ Final Step: Road Test & Inspection

  • Check for engine warning lights, unusual sounds, or exhaust leaks.
  • Your vehicle should now have improved emissions performance & efficiency!
