  Q: What precautions should be taken before servicing the exhaust heat shields for the catalytic converter and muffler on Mercury Marauder?

  A: All maintenance on exhaust heat shields for Catalytic Converters and Mufflers must start by disconnecting the power to the Air Suspension system to stop the air springs from unintentionally changing height which might cause shifting during work operations. Turn off the air suspension switch before you perform the first step of securely lifting up the vehicle. Check the catalytic converter to find any detached or absent heat shields. Worm clamps F0TZ-5A231-A or W705949-S300 should be used to secure loose heat shields then remove extra clamp ear. Heat shields need installation if they are missing; otherwise, replacing the catalytic converter becomes necessary. Finally, lower the vehicle.
