Heat shield rattling noise engine

I get a major rattle when I go at a normal speed. It stops or slows down when I coast, or when I accellerate. Someone told me it is the heat shield where the Manifold connects to the exhaust - and that it would need to be welded. Does this information sound correct? - the car still runs great 90k miles but the rattle is driving me mad.

Go to a a large hardware store and buy 2 band clamps that will fit around the heat shields and clamp them tight. This is the manufacturers approved fix for heat shield rattle. The fix sure beats the $1000.00 for a new catalytic converter assembly. I have done this fix dozens of times over the years of my car repair career.

Can you move it (heat shield) backwards and forwards against the manifold? If its that noisy you should be able to locate the rattle by touch?Cant be inside the engine, gear box,transmission or suspension.

you can also check if your wheel alingment is out,this can cause the same noise,if when you are driving on a straight road the steering look off center then have your alignment check.if you recently did the front struts that can cause the alignment to go out

SOURCE: Exhaust manifold gaskets

the ticking noise when cold is an exhaust leak.If it is the exhaust manifold gaskets,depending on the vehicle they can be very difficult to replace.in some cases you must remove many other parts even to see the manifolds.make sure when manifolds are off that they are checked for warpage,this is a simple test needing only a straight edge and feeler gague.ask your tech if he can see any broken manifold studs/bolts and if quote covers time for removing broken manifold studs/bolts,because if any are broken,this can take quite some time to extract the broken studs/bolts.

My Cady has developed a rattling noise under that increases when I accelated


A common cause for the "rattling" noise you've described is a loose heat shield for the catalytic converter. Many times, a weld will break loose leaving you with a hanging heat shield that vibrates and "rattles" while you drive. A trip to the muffler shop should be able to confirm this. By itself, a loose heat shield is not something major.

Another cause could be a loose exhaust hanger that holds the exhaust firmly in place. It too would tend to rattle more as you drive. Either way, it would appear on the surface that your issue is exhaust related. Best of luck and thank you for using Fixya!

Rattling noise coming from my 2005 mazda 6's engine. it only happens when i drive slowly such as going through kfc drive through


Good evening.
If this is a tinny type of rattle and it only happens at certain RPM's I would look for a loose heat shield over the exhaust pipes. Have someone apply the throttle until the rattles begins and listen under the car with a long screwdriver or a yardstick. Use the screwdriver to push on the various shields surrounding the manifold and pipes until the rattle stops. then use a hose clamp or two to tighten them up.
Also I see a lot of catalytic converters that become loose internally and rattle around inside it.
The only cure for that is to replace the converter.
If this rattle is an internal engine noise you should have an experienced mechanics ears give you an opinion.

Thank you for using FixYa.

1994 toyota pickup rattles at low speeds (~15-19 mph).


Check for loose heat shields the cover the exhaust. I find this is the source of many rattles. They are made of sheet metal and if they are not clip or tightened down the low vibration frequency when the car is running at slow speed will cause them the hit the exhaust pipe/ front mainfold.

When I step on the gas to increase speed there is a strange rattle coming from outside. It stops making the noise until I increase speed again.


check the exhaust pipe at the front of the engine there is a heat shield sometimes rusts at the spot weld and the shield rattles on the pipe
easy repair use a hose clamp open the hose clamp up put the clamp around the pipe reconnect the hose clamp slide it over the heat shield and tighten the clamp up

If it's doesn't sound like it's your engine which i am thinking not. Check to see if there any heat shield that may have come lose, like the heat shield to the spark plug wire or heat sheild along the down pipe. 
Good luck and hope this was the rattling your taking about as it heats up it expands and tighten's up.

A rattling noise from the engine bay


Check the heat shields on the exhaust system. They get loose from the extreme heat fluctuations work loose and rattle. Especially the one between the engine and firewall where the 02 sensor screws in. It probably rattles less after warm up because heat causes expansion which makes it tighter. Hope this helps.

Rattling noise during engine start up.. 2005 mitz galant 2.4l


You probably have a bad plug wire or cracked cap/roter , this can be seen at night in full darkness to pinpoint it. or you can buy a mechanics stethoscope (about 15.00 or less) and listen for it.

04 Endeavor rattling noise


I had the same problem! I crawled underneath the car and discovered that a heat shield on the exhaust header pipe was corroded and rattling against the exhaust pipe. (Before the muffler)
I removed the portion and clamps and solved the problem. Give it a try.
