My heat shield was loose and my dealer said it should be fine, but then it stormed and driving home I ran over a branch and when I got home I noticed the heat shield was ripped and dragging on the ground. It is pretty torn up and I'm thinking of just taking it off. Am I allowed to take it off? If so how should I go about taking it off?

View 11 RepliesI have a 2001 Passat GLS 1.8T Tip 34500 miles... Loose heat shields. Well, I couldn't find anything to fix, so I brought it to the dealer. They said that this was common on 2001 Passats with about 30k miles. All stock.
These were the symptoms that the car was exhibiting: At first it was a minor rattle that occurred at 1200-1400 rpm.......only when the engine was warm, and only when I was in drive. (I could not reproduce it in neutral)...
A few weeks later, it the engine rattled upon startup for half a second. I assumed that this was just the heat shield issue getting worse. Dealer says that I have a bad cam tensioner, and that they will replace it under warranty. However, I had to reschedule the repair for this week because they couldn't fit the 5 hour job in on Saturday.
He said that there is a spring backup for the hydraulic tensioner, but to get it fixed soon. Obviously I was going to have it fixed ASAP. What this cam tensioner does? Isn't there a chain that connects timing belt to cam shaft? Why does this need a tensioner? Does it change in tension?
My cars fuel system seems to have a problem, the check engine light came on, the loose fuel cap light has stayed on (caps been replaced) light continues. It revs high like going to 4 on the tach when I'm only going 35 so I try to accelerate slowly, when passing that's a problem, I suspect it's in the vacuum system. One mechanic told me it's nothing another, said he'd have to do a smoke test to discover the problem. It leaks gas if I only go a click over full, and the gas mileage isn't even the 25 mpg? Just wondering what it might be?
View 1 RepliesThis noise has me stumped. The frequency of noise seemed like the sway bar bushing. I fixed these and still making noise. Almost sounds like a something vibrating against the heat shield, but nothing. Seems to be front right. in the last year replaced the upper bearing struts. Shocks 4 years old. I have pushed the brakes and sound does not go away. In fact some days i drive the car and there is no noise. I just lowered the car. 132k
View 7 RepliesI have a 2012 screw 4x4 eb. I noticed under the truck there is some sort of heat shield under the transmission. The owners manual suggests removing this and the lower air dam before going off road. Can these items be removed permanently? Any effect on mpg's?
View 3 RepliesThis fiber material doesn't hold up to mud and sand very well. So much so, that the front hole ripped through. It won't stay fastened. I have all of the twist bolts still. Looking for a way to fix the shield so it will hold. I tried exposing a washer to it, but the epoxy doesn't like the material very well. I know the owners manual says to remove the shield if you are going to be off roading, but I hesitate to leave it off 100% of the time.
View 4 RepliesI want to replace the auto trans coolant lines on my 2001 F150 4.2L. I discovered I can actually see the top coolant line flare nut from outside the right wheel well, with the wheel and wheel liner removed. The lower line is just a few inches below. See photo, it's a little off, so the line connector is not seen:
The heat shield is just a little bit in the way for my hands, I have to put one through the red circled area. A 1/2" hex head bolt holds the shield to the frame (circled in green). This was easy to remove from the wheel well. After that the heat shield could be moved slightly away from the points I need to access.
I would prefer to unfasten the shield & move it out of the way for my hands. I found another bolt holding the rear end of the shield down to the frame, wasn't able to remove this - the bolt fastens to a U-nut in the frame that broke off & has trapped the bolt. Are there any other bolts fastening the heat shield down?
I was able to remove the old flare nuts with a 5/8" flare nut wrench, but have not been able to start the new nuts into their fittings, just not quite enough visibility and access.
I have a 2010 F150 FX4 with the 5.4L, and lately under slow movement (less that 20km/h it is sounding like there is a rattle. I can try to get a video of the sound later, now I'm wondering if the universal bearings in the driveshaft would be making this noise or if it could be the 4wd actuators failing? Would either of these make a loud rattle? (Sounds like a heat shield shaking but all are tight). Had a Ranger up until last year so just learning the ins and outs of F150 life.
View 5 RepliesOrdered my TBE couple of weeks ago, installed last week. I have been running the 100 octane tune for an entire week. Decided a couple of days ago to put it back to stock to see the difference. When I was running the 100 oct, I was pretty much on it the whole time. When I went back to stock I noticed some heat shield noise so I took it back to have them take a look. While on the lift I noticed a lot of soot in three different places.
View 19 RepliesI have a major rattling sound from under my car... it sounds exactly like a heat shield. I have been up under my car 5 times and I can not find a loose shield anywhere. the cat insulator mesh is still in perfect condition and it now seems the sounds is coming from somewhere in the back of the car, perhaps the muffler area.
This car does have the flapper mod done... could there be something inside the muffler itself? the car only has 40k on the ODO and I have not hit anything or do not have a dented muffler. As a fellow VW'er I do not want to be the only one running around town rattling...
I have what I think is a heat shield rattling at around 2500-2700 rpm. or maybe not? It's not that noticeable but it's driving me mad
Is there a more simple answer that it could be? Keep in mind I claim very very little mechanical knowledge.
I am going to my dealer tomorrow for something unrelated and I kinda want to get a head start when I go to talk to the service dudes.
I can't recall whos makes them. What are our options? I have the VMR intake if that matters.
View 16 RepliesI have a CTS Turbo intake and have recently purchased a heatshield. It did not come with instructions. I tried installing it this weekend and it was a no go. I'm assuming the pieces for the factory engine cover in the rear is what the heatshield needs to replace to bolt on. I couldn't get those off for the life of me.
View 5 RepliesI got a heat shield that just will not stop causing me grief. When I installed the headers and pipes I had a heat shield that was too close to the passenger side pipes. I bent it down some to clear the pipe and got rid of a nasty metallic sound I had on the throttle and making left hand turns. Well that little sound returned last week and I crawled under and looked and sure enough the heat shield was touching again.
Who knows why maybe a bit a spring sag. So yesterday I bent it down a little more. Today I start getting a nasty clunk on dips and especially when on a bump why turning. I crawl under there too look and find the same heat shield now has a huge gouge on the under side of it where the leaf spring near the rear bushing is smacking it. I'm sure Ford put it there for a good reason so hate to remove it.
First pic of the hacked up bend job I put on it.
Second pic of the gouge in the bottom of it where it's hitting.
I have a 42 DD tb exhaust. And so far I've used a 3" exhaust clamp over the last hanger (after the muffler) which raised the exhaust all the way up against the heatshield, eliminating the rattle over the rear axle beam. But the exhaust was rattling against the heatshield.
So I bought 15 ft of exhaust wrap and wrapped the section that comes in contact with the heatshield. It worked a bit but it still rattles a little! I hate this rattling! How to get rid of the rattling? Should I just use more exhaust wrap?
The catalytic converter shield is tack welded on the front end but free on the rear end. There was originally some braided wire packing at the rear to keep the shield from rattling against the pipes. Mine was deteriorated and had been damaged, I think, when I sustained some oil pan damage last summer -- big jolt to the system when running over a muffler on the highway.
The fix is simple. Bought a foot of 3/16" braided stainless steel cable. I used about 8 inches and layed in the lower bead line on the catalytic converter shield (see picture below). You can see a bit of the cable thru the gap in the upper/lower shield on the left side. (1/4" cable would be a better fit, but this will work for a long time.) Cost: $1.84
The local VW parts man dug out an exploded drawing of the system but it showed NO parts or packing for this problem.
I was driving down the PA turnpike and heard rear-end noise. I pulled over and this piece was hanging down on the right side in front of the rear tire and at the back edge of the rear door, right where the muffler is. I did a search and found this to be a common problem with the 330s but did not see anything on the 350s. I drove another 500 miles to the beach and then back home without any noticeable affects, but not that I looked underneath.
View 1 RepliesI am very mechanically inclined and up until now I can usually hear a noise and know exactly what the problem is, given enough time to listen..
The best I can describe the noise I am hearing, sounds like a cross between heat shield rattle or a syncro somehow stretched out and is loosely spinning around once in gear.. Hard to explain, but all gears shift perfectly..clutch was replaced at 102K and I am currently at 130K. Also I might be crazy but it sounds like I am starting to hear the noise in 3rd as well. I would post a sound clip, but its so faint it doesn't show up on my iphone..
The reason I am throwing it out there, is because half of the seriously trusted mechanics I know say it sounds like a bearing in the tranny going out, the other half, (3 of 6) can't even hear what I am talking about but its there.
Had an annoying vibration when pulling from a stop til up to speed or if I was going up a hill at low speed. Figured it was the exhaust heat shield so I took it in for service. I was told that it was indeed the heat shield and that there is a service bulletin regarding it. I believe they repaired it with a pair of clamps.
View 3 RepliesLooking for a cure for a heat shield that continually loosens, and causes a annoying rattle? I have been up under the car and re-tightened the suspected shield a couple times, the screw that holds the clip is not damaged, and the clip itself is not damaged... and on top of it all, I can never quite get that clip on tight enough to stop the rattle all together. is there a tool to get it tighter? i use micro needle nose pliers that fit and tighten it that way.
