- My Toyota is already 12 years old, and I’ve been noticing lately that it’s getting noisier than usual. I think the noise has something to do with a bad muffler. How can I tell if the muffler is already worn out?
Excessive noise can be traced to a number of exhaust system glitches such as cracks and holes in manifolds or pipes, blown-up gaskets, or a bad muffler, as you suspected. Rusts on the muffler or a small puncture or hole will turn the exhaust sound a bit louder. There could also be some thumping or clunking noise, which indicates a broken part in the system. The rattling in the muffler is probably caused by broken or loose baffles. Aside from rust and holes, you also need to check for thick, billow smoke from the pipes or water dripping from the muffler. If the engine temperature quickly rises to the point of overheating, then this could mean that you have an exhaust system problem.
- Can I clean the insides of the muffler? They say that this isn’t advisable and that this can be dangerous. Is there any truth to this claim? I just want to remove the accumulated dirt inside.
You’re only supposed to clean the exterior of the muffler. You don’t want the insides of the muffler to get rusty and corroded as you clean it, exposing it to rust and other elements. Cleaning the inner parts of the muffler may only shorten its life.
- What’s the best way to clean a Toyota muffler? What’s a good cleaning solution to use?
Remove surface dirt and soot using a dry rag or some paper towels. A mixture of 1 teaspoon dishwashing soap and a quart of warm water will be a good cleaning solution, especially for wiping out grease and removing stains on the muffler.
- Is it safe to polish a muffler? The one I got on my old Toyota SUV already looks muddy and even dingy. I just want to bring back its old shine.
You can use some polish on the muffler. However, you have to choose the right one according to the muffler finish or material. For instance, you may have to choose a chrome polish or look for a polish that’s safe or designed for aluminum. The polish should be applied using a dry, soft rag. A good alternative to the metal polish is toothpaste applied using a toothbrush. This can be used to restore the shiny metal surface. When polishing the muffler, make sure that it’s completely dry and clean.
- I found some small holes around the muffler, and I’m looking for a quick fix for this until I’m able to buy a new muffler and have this replaced completely. What would be my options for fixing the muffler leak?
Some muffler repair kits may include some kind of patch or epoxy. Before applying the epoxy or using the patch, the muffler should be sanded to get rid of rust and dirt first. The patch may be glued or welded on the punctured muffler. Muffler tape is also used to cover up the holes temporarily.
- I was shopping for some tape that I can use to cover up the muffler holes, but then my brother-in-law told me not to waste money on this repair solution because it simply won’t work. Is muffler tape really a bad idea?
The muffler tape doesn’t always work for all. Some who have used the muffler tape have complained that the tape eventually fell off. It didn’t bond to the pipe even if they have sanded down the surface and cleaned it thoroughly. You should consider this a temporary fix. If you want a more permanent solution, it would be best if you replace the muffler altogether, especially if there’s rust all over and there’s a lot of holes.
- How does a muffler bandage work?
A muffler bandage is a strip of cloth that’s chemically enhanced. It can be made out of fiberglass or silicone. The bandage is used to cover up the damaged area on the muffler. It’s wrapped around and pressed into place. The heat from the engine will harden the bandage and eventually seal it.
