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 RepliesI 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?
My wife drives a 2001 Suzuki XL7. While she was out, the exhaust heat shield fell off the catalytic converter. My question is does this affect the car's ability to function in any way? Is it still safe to drive? My wife is freaking out over it.
View 6 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've noticed that potentially my heat shield or whatever guard that is 1 step toward the front of the car from where the inlet pipe connects to the exhaust system may be the reason for my rattle at 2k and 3k rpms. i think its a heat shield but I am not sure. the thing is it seems properly mounted, nothing is cracked/broken/or loose. But when I do try and wiggle it it does make a slight creaking noise that sounds similar to the rattle I get. So I could foresee this as being my issue.
But, is there anyway to fix this rattle w/out just taking off the part? i figure its there for a reason and it looks like its held on in 2 places. But they're not nuts they almost look like spot welds or something. 1 on each side. What to do?
Something to get you all in here:
I recently purchased this truck and have towed a couple of times with it. It has 98,000 miles and I do not know if the automatic transmission fluid has been changed. Should I have it flushed or drop the pan and change it? I have a lift so doing the change is no problem, although it might be worth it to pay a transmission shop to do it.
Also, I hear what appears to be like a heat shield rattle or something that sounds kinda like an exhaust leak during loaded acceleration. What to look for to locate the noise? One last question, the air bag light is on sometimes then off sometimes. Any known air bag light issues? I love the truck, hate the gas mileage!
Pulled into a parking space as usual the other night and when backing out, I badly ripped up the "radiator shield" (if its called that) plastic cover underneath my car. I ended up removing it all together after removing a few remaining clips holding it in place and drove home without problem. It looks like it protects the radiator.... What this part is called?
View 10 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 RepliesThe 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.
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 1 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.
View 24 RepliesI have a 2008 Camry Hybrid and the rear muffler heat shield has come loose and is about to fall off. The car is running great and has had no real issues.
View 6 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?
