parado25 Posted April 29, 2006 Share Posted April 29, 2006 I have a 2003 Legacy 2.5GT with about 75000km and a K&N air filter. Just recently I've been noticing a rattling noise coming from under the car whenever the rpm is around or above 3000. Does anyone know how to rid the rattling noise I'm experiencing? Could it be something loose underneath? Thanks. Link to comment Share on other sites More sharing options...
RIVERWHITE Posted April 29, 2006 Share Posted April 29, 2006 I am just about to put my lady up on the lift as I too have a metallic buzz/rattle when around 3-3500k. I have a feeling it is the heat shield over the midpipe that is loos after a uppipe/downpipe install a few weeks ago. Where is it coming from and is it metallic? might be exhaust...

MitchGT Posted April 30, 2006 Share Posted April 30, 2006 It is definately the heat shield. It is very common on the BEs and almost always happens around the 3k rpm mark. I just cut mine off. Weird, I joined this forum a long time ago but this is my first post. Link to comment Share on other sites More sharing options...

dplacen Posted April 30, 2006 Share Posted April 30, 2006 Heat shields rattle very common on subaru's! I fix them all the time. Link to comment Share on other sites More sharing options...
RIVERWHITE Posted April 30, 2006 Share Posted April 30, 2006 so aside from a complete removal what the fix? nylon washers? metal w/ high temp latex to buffer? Link to comment Share on other sites More sharing options...
LightShifter Posted June 18, 2010 Share Posted June 18, 2010 From what I've gathered, heat sheild rattles can be fixed by simply getting a $2 stainless steel clamp from Home Depot or someplace (the kind one would use on a clothes dryer vent hose) and wrapping it around the loose shield. That's what I'm trying tomorrow. Removing it does not sound like a very safe idea to me. Link to comment Share on other sites More sharing options...
New Subaru Fan Posted June 19, 2010 Share Posted June 19, 2010 What is actually the purpose of the heat shields? I had that annoying rattling noise and just removed the covers (I assume they were heat shields) from the exhaust ducts. Can anyone tell me what the disadvantage/problems of driving without those covers is? Link to comment Share on other sites More sharing options...

Can anyone tell me what the disadvantage/problems of driving without those covers is? Its SO simple you answerd your own question. it is a HEAT SHIELD. it helps absorb and reflect heat away from the cab and well the drive shaft is right above it disadvantages: increased floor/cab temps (could be useful in the winter) possible melting of things that were once hidden (doubtful though) I fixed mine with 4 metal screws and air powered drill, even easier than taking it all off!

Thanks for the answer. I think (or at least I hope) there's nothing superfluous on Subaru cars. Although even mechanics in the Subaru garage didn't oppose my removing the heat shields along with a turbo shield. Anyway the annoying rattling noise was eliminated forever!

LuciasDark Posted July 16, 2010 Share Posted July 16, 2010 Hi everyone. had my car just under a year now. havnt had that many issues with it except for very loose inspection plate on the crossmember. when i had that fixed i got another sound which is like a rattling sound and as far as i can tell it doesnt occur when idle but when moving it occurs at the 3000rpm mark. good chance its heat pipe? also at 70 kph in 5th gear (manual transmission) 2.5i there is like a deep 'huming' sound. could this also be linked to the heat shield?
