Heat shields

If you’ve noticed your Honda CR-V making a rattling noise when driving, you can often fix it yourself by replacing the heat shields. The good news is that the fix is simple and won’t take you more than a few hours. One of the most common causes of rattling noises is a loose heat shield. Heat shields are usually located around the exhaust components, so if they’re loose, it can make a vehicle rattle.

The heat shields protect the underbody components and are essential to safe and comfortable driving. They are removable, but you’ll have to remove the old heat shields first before you replace them. If they’re loose, you can use hose clamps to hold them in place.

Rattling noises can come from a variety of sources, including the exhaust, timing chain, and loose accessories. Fortunately, these noises aren’t typically a sign of a serious problem. In many cases, they’re caused by a rattling exhaust system, which may need replacement.

Timing chain

If you have a Honda Cr-V and you’ve noticed the timing chain is making a rattling noise while driving, you may be experiencing a timing chain failure. This faulty component can affect the engine’s timing and fuel efficiency. It can also damage the vehicle’s electrical system and battery life. The problem could be as dangerous as an electrical fire, so you should contact a service department immediately.

To check your Honda cr-V’s timing chain, remove the timing chain cover. Using a long handle socket, loosen the adjusting bolts on each component. Use a stethoscope to listen for scraping or rattling sounds near the timing chain cover.

If you notice a rattling noise when driving, your timing chain may be too loose. You may need to replace it. This is not a permanent fix, as the rattle will come back after a while.

Catalytic converter

If your car is making a rattling noise while driving, you may have to replace your catalytic converter. This process usually involves replacing faulty parts. If the noise is still present, you may want to try a used catalytic converter that comes with a warranty. Make sure that the catalytic converter you choose is compatible with your vehicle, however.

The most common cause of this noise is a loose heat shield. This heat shield is causing the noise by rattling against the catalytic converter. You can check for loose bolts by tapping on the heat shield. You can also clean the catalytic converter by adding fuel additives.

Another common reason for the rattling noise is a failed or clogged catalytic converter. A blocked or faulty catalytic converter may result in a failed emissions test. Whether the noise is coming from the catalytic converter or something else, it is a serious problem. If the converter is leaking or clogged, it can cause damage to your engine and cause it to misfire.


If you have a Honda CR-V and it makes a rattling noise while driving, you should call a mechanic to have it checked. The rattling noise can be caused by a malfunctioning VTC actuator. This actuator can cause a rattling noise when driving or starting the car. It can cost over $1,000 to replace, and it can damage the timing chain, which can cost over $5k to replace. The rattling noise is most noticeable after cold starts.

Another problem that can cause a rattling noise is a bad actuator pin. This pin can become stuck in the VTC actuator. Fortunately, it is a mechanical device, so you can replace it without removing the intake camshaft. A rattling noise is common when the VTC actuator pin gets stuck.

Honda has made an 800 number available to help customers solve this problem. A representative from Honda’s 800 number says that this noise is normal for a 2014 Honda CRV, but that it is not an issue with newer models. The company has issued a service bulletin on this issue, and there is no recall. However, if you hear a rattling noise while driving, you may want to contact a mechanic right away.
