Repair Instructions

Step 1: Drain Coolant

  • Ensure the engine is completely cool.
  • Place a drain pan under the vehicle.
  • Open the radiator drain plug or disconnect the lower radiator hose to drain the coolant.

Step 2: Remove the Radiator

  1. Remove Protective Covers:

    • Detach any engine covers or shields obstructing access to the radiator.
  2. Disconnect Hoses and Fittings:

    • Use pliers to remove the hose clamps from the upper and lower radiator hoses.
    • Carefully twist and pull hoses off the radiator fittings.
    • Disconnect any transmission cooler lines if applicable.
  3. Remove Mounting Bolts:

    • Use a socket set to remove the bolts securing the radiator to the support frame.
    • Note the bolt locations for reinstallation.
  4. Detach Fan Assembly:

    • Unplug the electrical connector for the radiator fan.
    • Remove the fan assembly if it's attached to the radiator.
  5. Remove the Radiator:

    • Carefully lift the radiator out of the engine bay, ensuring not to damage any surrounding components.

Step 3: Install New Radiator

  1. Position New Radiator:

    • Place the new radiator into position, ensuring alignment with mounting points.
  2. Reattach Fan Assembly:

    • Secure the fan assembly to the radiator if detached earlier.
    • Reconnect the electrical connector for the fan.
  3. Reconnect Hoses and Fittings:

    • Attach the upper and lower radiator hoses using new hose clamps.
    • Reconnect any transmission cooler lines if applicable.
  4. Secure Radiator:

    • Fasten the radiator with mounting bolts using a torque wrench to the specified torque value in the service manual.

Step 4: Refill Coolant

  • Mix new coolant with distilled water if required to the correct ratio.
  • Fill the radiator and reservoir with coolant.
  • Follow the bleeding procedure for the cooling system to remove air pockets.

Step 5: Test and Verify

  1. Start the Engine:

    • Run the engine and monitor the temperature gauge for normal operation.
    • Check for leaks around the radiator and hose connections.
  2. Recheck Coolant Levels:

    • Once the engine has cooled, verify the coolant level in the reservoir and top off as needed.

Conclusion

Addressing radiator failure promptly can prevent significant engine damage and maintain vehicle reliability. Always follow safety protocols and consult the Audi Q5 FY service manual for specific torque settings and procedures. If unsure about any step, consider seeking professional assistance.
