The heat that is produced by the exhaust system of an engine is much higher than most people realize. With all of the vital and sensitive components that are on your engine,...
This seems to be a torque converter issue. The bolts are probably loose between the converter and the flex plate. To get to the torque converter bolts, you will need to remove the starter from the engine and then you...
This is common due to the fact that just underneath this area is where the transmission and drive train is located which generates a lot of heat. I would recommend having a certified expert, like one from YourMechanic, come to...
Yes, a loose heat shield, exhaust leak, damaged muffler or catalytic converter, or even a faulty engine mount may all contribute to a rattling noise. The exhaust system and motor mounts need to be inspected for contact issues. You may...
If this all occurred right after the brakes were done, then it may be a backing plate hitting the rotor. This will cause the noise and can also cause some odor. It may also be a failing bearing which can...
You may have a heat shield that has a broken weld or bent and vibrating until the heat changes the shape of the metal and it stops. I have see catalyst also rattle inside and then stop within a few...
No, it's not necessary. It's a shield that keeps your oil pan from getting hot. Those Volkswagens are so squirrely, if you want to talk about over-engineered German nonsense. Their oil pans are two-part oil pans on most of...
Hi there. Check the exhaust system for any heat shields that are loose. If the heat shields are loose, you can try to tighten them up. Some heat shields are welded in place. If there is no loose heat shields,...
Hello, the exhaust system noise can be created from a heat shield (light tin type sound). Rattling could be from a hanger which support the system. A muffler and catalytic convertor can internally make a rattle type noise. The vehicle...
Under engine shields keep water, dirt, and debris off of engine electrical components and also keep combustible debris from roadways, such as paper and plastic, from being drawn up into the engine compartment possibly contacting the hot exhaust manifold. So,...
Hi there. The noise that you are hearing is heat shields on the exhaust system are loose causing a rattling noise. Either the shield on the manifolds are loose or the shields on the catalytic converter are loose. If you...
Hi there. Sounds like the exhaust heat shields are loose on the exhaust system and rattling underneath the vehicle. Go under the vehicle and check to see which shield is vibrating and tighten them up. If the heat shield is...
Hi there. Sounds like one of the heat shields on the exhaust system has broken a weld and is vibrating as the engine is revved up. Jack the vehicle up and put on jack stands. Go under the vehicle and...
Hi there. The noise could be a heat shield that is loose on your engine causing the loud vibration noise and it will appear to be a rattling noise. If the rattling noise is more choppy and not fast and...
The heat shield is designed to keep the engine at a specific temperature. I recommend leaving the heat shield on but fixing it to where it does not vibrate. Look for any cracks or broken bolts to see if the...
The part that is covering the oxygen sensor is the heat shield on the exhaust manifold. You will have to remove the heat shield first to get the O2 sensor off. If you need further assistance with removing the heat...
Hello, thank you for writing in. The shields that are mounted on the bottom of the car provide the most protection from water and road debris. While they do provide this protection, failure of the rack and pinion should not...
