Having problems with your 2003 Mercury Mountaineer ?

03 Mountaineer AWD Premier V8 rattling noise under vehicle

\015 Ford told me it was torque converter. Replaced, still same noise. Then catalytic converter, then flywheel. Still makes the same noise. Finally someone said it was a loose heat shield, but they can't get to it to fix. How would you fix a loosed heat shield. thanks\015 Posted / edited by AnonymousUser on : 20-09-2021

Answers :

If its the heat shield against the underside.its install with fender style aluminum rivets( if you do it be very careful not to drill into a harness) If its the heat shield around the CAT then you should replace the cat. You can try to repair it with a pair of long hose clamps but I don't advise removing it. In the wrong environment the heat could cause a grass fire. or ignite trash that may get caught or blown underneath. Good luck.
