Honda accord v6 heat shield rattle.

[@ridiculousrobby]

This ended up being the heat shield around the primary catalytic converter. The heat shield rusted off around the bolts allowing it to rattle. You can either replace the heat shield or just put a big hose clamp around it.

can a broken heat shield break the car to the point where it wont start?

Hearing the same sound after I got mine back from the dealership. (Oil pan replacement) I started to take it back to them but decided to diagnose the issue myself and stumbled across your video. I'm thinking they may have not tighten the heat shield back up if they had to remove it. Gonna check it out and see. Thanks!

[@tyken144]

i just had this happen on my 06 corolla, i immediately figured it was a bad cat aswell. fortunately it ended up just being the heat shield. i used zip-ties to anchor the cover back in to place🤘🏼

My car is making this exact sounding rattle and I thought I was going insane so thank you!

[@s2kceltin]

FINALLY! THIS IS THE SOUND

[@hanmingzu5931]

1:48 is start of a good one

[@Capstonetoy]

My odyssey started making this noise. Thought my engine was going out. I’m sure it’s going to be this as well considering it sounds the same and they have the same engine. Gotta deal with it for now until it warms up 10 degree weather is too cold for me to get under the car. Thanks for the vid man!

[@ridiculousrobby]

Usually it’s the catalytic converter heat shield rattling. Most people just put a hose clamp around it and it stops it.

[@MacroAnimationStudio]

I changed oil twice I put bunch of injectors cleaner into the fuel 😂 to end up being that thing

[@hypotrucksjourney3214]

My 08 Ridgeline makes this exact sound. ill look at the heat shield both by the engine and by the cat and muffler. nice to see a video that does have the same problem

[@xx_-xx6325]

Oh thank the lord. This is the exact sound that is happening in my car, mines at 1800-2000 rpm, thought it was my subs for the longest time before i left them at home. My heart dropped when i heard it again, went through every problem it could have been but this is it. Thank you !

[@benalisonbrown]

Same problem with my car, it won't rattle when someone is watching... so annoying. I can't get it to act up in front of a mechanic... rattles when it's cold, ac on and at idles the first 15 minutes I drive it. I'll take it to someone. I hope it works! Many Thanks!

[@charliedathorne]

Had this on my Civic 2001, the cars history is the catalytic converter was stolen so had that fixed but couldn't work out where THIS noise was coming from, thanks for the tip!

[@Stizzy_BK]

2020 Elantra same issue.. Just bought the car & immediately wasn't too concerned wt the rattle, figured it was the heat shield bc its only upon acceleration at low rpms, you confirmed my thoughts😅 Fixing this week, hopefully 😂👍

[@CadenceFilmsInc]

This is what my issue was, heat shield had fallen onto exhaust, new bolts fixed it. Thanks

[@onilovni1234]

One day my 2010 Acura TL had the same sound at 2000-2200 RPM while rolling under load only. I watched this video and it turned out to be the catalytic converter heat shield that was rusted around the bolts. It did not make the sound while I grabbed it under the car but it was definitely the culprit since the car is 100% noise free now. I did not care to install a new one since it's only useful if you park under tall gras. Also, not all cars have a heat shield under the catalytic converter.

[@vanlo1178]

My Acura MDX is doing this it’s an older 2004. I can tell it’s rattling from the passenger side of the engine. Mine has gotten way louder with time. Not sure why it’s bad when I shift into 20-30 mph. But now it’s just loud even running. 😫

[@unexpectedkid5880]

Same, I can’t figure out the issue

[@1234loci]

My freshly bought (used) Toyota Auris does this and my heart sank when it started doing this raspy metallic kind of resonating sound. It’s not yet diagnosed by a professional but it’s sounds awfully similar to 1:48. Even worse with the windows down. I’m really hoping it’s a heat shield and not the engine/transmission. Only comes out when accelerating.

[@juli-hannah3569]

I can hear it because I recognize that rattle lol shit dude. I’ve been seeing it’s from the heat shield. Just get under there and knock on stuff after the car has cooled down. Also to anyone wanting to know how to fix it. Use a hose clamp or search loose rattling heat shields.

[@ridiculousrobby]

yep i put a hose clamp around the entire heat shield on the front side of the engine and it went away. common on these honda v6s.

[@anthonyficuciello1133]

Thanks for the video. Have a 2004 accord ex V6 with automatic transmission. Rattling Started at 165k miles. And only rattles when accelerating in drive at 2k-2.5k rpm, not 2k rpm in neutral or park. Was wondering if the problem was fixed by replacing the actual upper and lower heat shields or replacing just loose bolts on the upper and lower heat shield?

[@ridiculousrobby]

Most of the time the heat shield is so rust that it breaks around the bolts. Just put a hose clamp around the whole thing or you can replace the heat shield and bolts. Just replacing the bolt won’t fix it usually.

[@markallisonmc]

I have the same issue on a 2006 Honda Odyssey 200K. I figured it was a exhaust system heat shelf or break stone shield coming loose. Time to get under the van. Thank you 😊

[@dudeonbike1629]

Just FYI everyone this heat shield rattle is tricky to track down. I work on cars regularly and I put several exhaust clamps around it did not solve my problem so good luck.

What about rattling at an idle also? Thx for the video

I can’t hear the noise really, but on my Honda it also makes a rattling noise at 2k-2.5k rpms too

Most likely the heat shield on the cats. Most people put a hose clamp around the heat shield to stop it. Replacing it would also work but it’s difficult to change the heat shield unless it’s a 4 cylinder with more room to work.

[@onilovni1234]

Is it normal if I only hear it on my Acura TL when I drive? Because the heat shields noises are linked to engine gas and you don't need to actually drive your car to create exhaust gas...

[@ridiculousrobby]

Anthony HT the first time I had heat shield rattle was only at idle, that’s was the heat shield on the back side of the engine. Second time I had heat shield rattle was when driving at about 2k rpms, that’s was the front side of the engine. It’s different on every car but because the accord and tl are pretty much the same car. I would advise you to check out the heat shields on the catalytic converter‘s.

[@ridiculousrobby]

Anthony HT also is your Acura TL SHAWD or front wheel wheel drive?

[@onilovni1234]

@@ridiculousrobby SHAWD with manual gearbox. I supposed the rattling heat shield would be close to the engine if I only hear it when the engine is moving a bit under load. One weird thing I noticed is that if I drive for about 2 minutes at 100kph and I slow down and start re-accelerating like you did, the noise completely stops for a couple accelerations, like if the exhaust had cooled down a bit. And it restarts like before. Could it also be a bad motor mount because it's the same principle I guess?

[@ridiculousrobby]

Anthony HT motor mounts are easy to check. But it’s probably the heat shields. Very common on the j series v6. Cheap fix too.

[@TheJunTV]

Did u find the problem here?

[@ridiculousrobby]

Jun Angeles I found the problem. It was the heat shield on front side of the engine. Both my front and rear heat shields had this problem and the heat shield can either be replaced or put a hose clamp around it.

[@103720C]

@@ridiculousrobby I stopped at a muffler shop and they welded for free but the sound came back. They did inform me that it was the front near the engine and not the heat shield around the cat. I'm gonna have to clamp it down like everyone else. Lol
