Volkswagen Beetle Exhaust

Problems of the Volkswagen Beetle Exhaust

Exhaust problems are very common in vehicles, such as the Volkswagen Beetle. A damaged one can interfere with the performance of the car since it wouldn't be able to clear harmful elements from the engine. It could also pose health issues if this problem won't be diagnosed right away. Here are some common problems with the Volkswagen Beetle exhaust that you can troubleshoot on your own.

Loud noises from the exhaust

If you hear loud racecar-like noises every time you step on the accelerator, there's probably a common case of the disintegrating exhaust system syndrome. This is caused by a hole that's somewhere in the exhaust system or a leak. The easiest way to troubleshoot this is to start up the Beetle to listen and tell where the noise is coming from. Check around the engine bay, muffler, and under the car. Also check if there are any holes in the piping that can cause leaks.

Beat the heat

Heat expansion and contraction are common causes of leakage in the exhaust system. Check the exhaust manifold and cylinder head since leaks happen when these two come in contact with each other. If there are paint discolorations or even burns around the ports of the cylinder head, then there's probably heat problem in the exhaust of the Volkswagen Beetle.

Lower than expected

Another way to diagnose the exhaust for problems is by starting the vehicle and inspecting the engine's intake manifold vacuum. Normally, the reading should be more or less 18 inches, but if it's lower than that, there's a restriction in the exhaust.

Checking the effectiveness of the exhaust system

One of the easiest ways to check the effectiveness of the Volkswagen Beetle exhaust is by taking out its catalytic converter and holding it up under a bright light. If the light goes through it, the converter is working well. But if it doesn't, then this needs to be replaced to let the exhaust run effectively again.

Other tips for troubleshooting

Make sure to repair these problems right away because constant leaking of the exhaust can lead to detrimental health issues. If carbon monoxide, which is an odorless and colorless gas, enters the vehicle cabin, it could kill the driver and the passengers.

  • Volkswagen Beetle Exhaust: How to Keep it in Top Shape 04 March 2014

    If you want to keep the efficiency and great performance of your Volkswagen Beetle exhaust, you have to make sure that it's always in top shape and properly maintained. There are a lot of causes that can damage the exhaust, such as leaks or cracks in the pipe. The best way to keep it working for a longer time is by preventing such things to happen. Here are some tips to help you keep the Volkswagen Beetle exhaust in good condition.

    • Preparations before inspecting the exhaust.Before working on the exhaust, make sure that you wear safety gear to avoid any injury. Make sure that you wear gloves since the exhaust parts can be extremely heated up. The best place to check the exhaust is at a well-ventilated area since inhaling exhaust gases can also be detrimental to the health.
    • Working on a hoist.When inspecting the exhaust for any damage like leaks or cracks, the best way to do it is on a hoist. This way, you'd be able to gain better access when it's raised so that you'll have enough room to safely walk underneath the vehicle. However, you have to make sure that the hoist is locked in place to avoid any injuries that could possibly happen.
    • Where to start inspecting.The best place to start inspecting is at the water injection elbow and pipe. Rate it for hot water. The car heater hose can be used during the process. Check if there's corrosion and leaks. If you want to replace the hose clamps, make sure they're stainless steel so that it won't be prone to corrosion. See to it that the clamps are not too tight, which is a common mistake, because it can lead to premature failure. You wouldn't want that to happen especially since the goal is to make the exhaust system last longer.
    • What to do when the flange gasket is leaking.If you discover that the flange gasket is leaking, the best thing that you can do is by taking it to the muffler shop right away. This is caused by hot gases that are escaping the exhaust. If you don't get it repaired right away, your car can possibly catch fire.
