Get to Know the Problems of a Defective Toyota Highlander Muffler

The muffler, or otherwise known as silencer in British, is basically built to keep the vehicle quiet to let the driver comfortably drive without any noise. But, it's inevitable for the Toyota Highlander muffler to give up since this is not made to last forever. Sooner or later, replacement would be needed in order for your car to run smoothly. It's good to diagnose the problem as early as now. Here are some troubleshooting tips to help you get to know the problems of a defective Toyota Highlander muffler.

Signs of rust and corrosion

Most mufflers are made of substandard steel and are prone to corrosion and rust. This is one of the common problems that the car muffler experiences especially if you drive under the rain or over puddles most of the time. Also, check if there are any signs of corrosion. You can clean the underside of your vehicle at least once a week to keep future corrosion from developing. If you're not satisfied and you really want to have a good-looking muffler, then you always have the luxury of replacing it with a new one. It's a good way to customize your ride as well.

Low gas mileage

Check if the gas mileage of your Toyota Highlander has dropped because this means that the oxygen sensor is getting worn out. Take note that a problematic sensor can lead to damaging the muffler.

Hissing noises

If you start hearing hissing or even popping noises coming from the engine, then it could mean that there is a leak somewhere in the exhaust system. Don't let a leak get any worse, so have it checked right away. It can produce carbon monoxide gases, which can definitely be detrimental to the health.

Black soot

The exterior look of the muffler can also reflect how much it is worn. Inspect the outside and check if there's black dirt that's covering the part. If so, you have to get the muffler replaced as soon as possible.

Heated floor

If the floor gets hot as you drive or if you can smell sulfur or any odd smell at all, it's an indication that you have a clogged catalytic converter. This must be replaced right away to avoid damaging the muffler.

  • How to Keep the Toyota Highlander Muffler in Good Condition

    The Toyota Highlander muffler is designed to eliminate the noise that your vehicle makes to enable you to have a smooth and comfortable trip. However, it's common for the muffler to rust especially if it's been exposed to water or rain because moisture can build up and rot the part. There are some things you can do to lengthen the life of the muffler and that's by following some of these useful tips.


    Don't clean the inside of the muffler.

    Although it's quite tempting to clean the inside of the muffler because you know very well that it's full of grime and dirt, it's a good idea not to. This can cause further corrosion and rust and will surely shorten the life of the muffler.


    Get rid of grease.

    It's unavoidable for the muffler to get greasy over time, but there's something you can do to get rid of it. Clean the outer part with a mixture of dishwashing soap and a bucket of warm water. This will let you wash off grease and hard-to-remove stains. If you're not satisfied yet, you can always repeat the process. However, be careful not to put too much pressure when sanitizing it because scratching can cause premature wear and corrosion.


    Polish it off.

    A new muffler looks really shiny; an old one looks rusty and dull. If you want to restore its previous image, you can do so by applying metal polish. Make sure to get the right one because there are different kinds of polishes that are made for chrome and aluminum.


    Clean off the soot.

    Another way to lengthen the life of the muffler is by cleaning the outer part by using a dry rag or paper towels. You can do this every time you get home from a trip; if it's too much of a hassle, a weekly cleanup will do. This will surely prevent your muffler from corroding.


    Other tip

    Sometimes, if the rusty or corroded muffler can't be fixed, you have no other choice but to replace it with a new one instead. This way, you'll be able to drive with a brand new and shiny Toyota Highlander muffler.
