One of the common causes of your muffler going bad can be easily heard from your vehicle when driving. Listen closely for anything rumbling under your car that is not intentional. This could indicate a problem inside your muffler. Other kinds of sounds you should watch out for are pops, hisses, and thumps. If you hear any of these, be sure to take a look at your mufflers as soon as possible. There are many causes for this to happen, such as leaks due from rust, broken pipes, or damage from the inside.

  • Easy Upkeep Tips for Your Nissan Pathfinder Muffler

    The Nissan Pathfinder muffler is responsible for keeping the noise levels of your car's exhaust as low as possible. Furthermore, it also ensures that the harmful gases go only towards the outside your vehicle. Thus, it is important that the part is maintained in constant, optimal condition. Failure to do so will cause a variety of troubles for the driver, from unwanted noises to severe exhaust problems. If you want to save your time and money from having to get your muffler repaired from the car shop, then here are some maintenance tips:

    Patch holes.

    In time, dirt and debris will slowly wear down your muffler. This will result in holes appearing, which could greatly affect your muffler's performance. Another cause for holes is rust forming up caused by condensation from the interior of the part. A corroding muffler form the inside out is rather common, so immediate repairs is highly recommended. After locating the hole, use sand paper or a file to remove any loose rust. Then, clean the area using alcohol, to remove any microscopic particles. After that, plug up the holes in your muffler using some exhaust pipe putty. This material can be bought at any auto repair shop at a considerable price, and is the best way to patch the holes completely, with no risk of leaks afterwards. Remember to not use the car immediately after application, as it requires some time to dry off.

    Tighten a loose muffler.

    Shakes and rattles are caused by your muffler coming off loose. If you are hearing sounds caused by scraping, then there is a high possibility that the straps holding the muffler or the bolts in your bracket are loose or broken. Fixing this problem is relatively easy with very basic mechanical knowledge required. If the bolts are the problem, all you have to do is just retighten them using the correct wrench. If the brackets are the cause, then position the muffler back in place, then wrap a steel zip tie around the part. Make sure the you wrap it tight and tie it properly, so that you will not experience any further loose muffler problems.
