Seeking easy fix for shield over muffler

Post by **JimBee** » 08 Aug 2018, 19:44

Four studs are toast, shield resting on muffler. There doesn't seem to be as easy way to get fasteners in above the muffler. Seeking an easy solution.

Hi Jim, remind us of which model you have and is it FWD? Which muffler? My last FWD had the catalyser, a central muffler just forward of the rear axle and then one near the back bumper. Which one are you trying to fix?

Neil: The car is a 96 850 wagon. The forward catalytic converter has a shield over it; that one is fine.

The muffler in question is further back, but forward of the rear suspension links. It's the larger pancake style. The single exhaust system has only the one pipe and one muffler.

I just removed the heat shield when that happened to me on the middle muffler. Easy "fix". Never noticed any difference.

On some of my shields I have been able to get away with larger washers - on both sides. From the sounds of your situation this will not work. On a 2002 XC70 I tightly wrapped some copper ground wire (no plastic casing) from some Romax pieces I had lying around - this has held up for 2 1/2 years. I started on one side and kept it tight wrapping it around with 3/4-1" between windings then doubled back - sorta a crisscross pattern. No rattles. I suppose if you are afraid of rattles put some high temp RTV on the shield and then rap it - I have never tried this, but have heard of people doing it. In the end if it doesn't work you can go to step two.

Some just remove the head shield.

I would look at the suggestion above with some high temp RTV and or construction cement and 'glue' it in place.

Glue. Hmmm. Hadn't though of that. Or maybe JB Weld used the same way?

But then if having it there or not doesn't make a difference, well the easiest fix like Rattnalle suggested is to keep it in the spare parts kit and not worry about it. I'm not sure how long it had been sitting on top of the muffler, but tooling around the last few days without it I haven't noticed excessive heat onboard.
