exhaust heat shield falling down

[wpginterceptor]

Anybody else have this problem?? the heat shield around the exhaust is startin to fall... Should I just rip it out or try and put it back??

I would grab a few sheet metal screws and washers and secure it again. The heat shields are there for a reason.

Wife’s Journey 3.6  heat guard started hanging down and rubbing on driveshaft, had to add fasteners last year.

There have been grass fires from missing catalytic converter guards.  Carpeting and electrical is protected sometimes as well. They are really flimsy and not well secured.

The 6mm-1 bolts securing the heat shields have a rounded "washer" to spread the compression on the thin/soft aluminum but I just found 3 locations where the "washer" has worked through the aluminum.  I've cleaned up the remaining threads on the original bolts with a die and will put larger washers on with an additional nut as the original nut is rusted on.

Yeah common. I've seen pie  plates thicker than that crappy shield. Fender washers work great on the bigger holes.

Here are some pics

2. shows a large washer under the aluminum

3. shows a large and small washer above the aluminum with a new 6mm-1 nylon insert lock nut

If the studs aren't too rusted yet you might want to reinforce the other fastener locationsnow. Not later.

 

I'm in rust belt so I had a harder time cleaning up studs. Fender washers allow just one washer, but enough thread there anyway.

 The underside of that journey from the peg is amazing, in first post. No salt, sigh.
