The car is old, and many people have encountered the phenomenon of rust on the exhaust pipe. Some surfaces are corroded in a large area, some are partially corroded, and there are holes in the corroded place. So what to do if the exhaust pipe is rusted? Is there a way to prevent rust? Today we will talk about these problems of exhaust pipes.

Under normal circumstances, if the rust on the outside of the exhaust pipe is only superficial and does not cause obvious damage to the pipe structure, basically you can only watch it getting more and more rusty, and there is no way to do anti-rust treatment, because the exhaust pipe The temperature is very high, and the surface cannot be sprayed with anti-rust materials. However, the rust of the exhaust pipe does not gradually rust from the outside to the inside, but starts to rust from the inside and gradually spreads outward. Because the environment is humid, it is easy to rust. As long as it's not raining, the outside of the exhaust pipe is always dry without much rust. Even if there is rust, it is only very slight. Although the area is large, the depth is not deep. So in general, don't worry about rusting on the outside. However, the inside of the exhaust pipe is in a humid state for a long time. As long as you drive, water will be produced in the exhaust pipe, and some cars can clearly see the water flow out. If you don't dry it for a long time after parking, it will start to rust from the place with a lot of moisture inside, and the rust will become more and more serious until the rust reaches the outside and becomes a big hole.

Exhaust pipe rust is inevitable. If there is rust on the inside of the exhaust pipe, you should have it checked by a qualified mechanic or auto technician. Depending on the extent of the rust and the condition of the rest of the exhaust system, they may recommend that you repair or replace the affected components. Ignoring this issue can lead to further damage or failure of the exhaust system, which can be dangerous and cause problems with vehicle performance.

Here are some suggestions for preventing exhaust pipe rust for your reference:

  • Replacing the exhaust pipe with high-quality will generally have a longer service life. For example, stainless steel parts that are less prone to rust can be used. Some exhaust pipes are very thin and made of poor materials, so they will rust faster.
  • If there is water in the exhaust pipe and you hear a buzzing sound, deal with it in time.
  • Regular cleaning of the exhaust pipe will help to remove dirt and debris that can cause rust, also pay attention to clear the drain hole to avoid it from clogging.
  • In the process of using the vehicle in normal times, we must pay attention to avoid driving under particularly bad road conditions. When washing the car, be careful not to flush the exhaust pipe directly.
  • Remember to keep your exhaust system well maintained, including promptly repairing any leaks.
