Cadillac Parts 101: Muffler

There are so many Cadillac parts, it can be hard to keep track. Here at Zeigler Cadillac of Lincolnwood, we want you to feel informed and empowered about how your car works. Let’s take a look at the crucial yet underappreciated muffler.

What Does a Muffler Do?

Located under the rear of your Cadillac, the muffler performs several important functions all at once. The muffler is the core component of your car’s exhaust system. It muffles engine noise and controls the engine’s backpressure.

As the valves in your engine constantly move up and down and against each other, backpressure builds up. Mufflers help regulate this pressure, and they need to be kept in good shape.

Things to Watch For

Rust can be detrimental to your muffler’s performance. Water can collect in the exhaust and if the engine doesn’t get hot enough to burn it off, the condensation can cause the muffler to rust.

Holes or loose parts rattling around the exhaust portion of the car can lead to cracks in the muffler wall. These can seriously impact your exhaust over time.

Signs Your Muffler Needs Service

Like any car part, your Cadillac muffler will go through some wear and tear. Here are some signs that your muffler may need servicing.

Is your exhaust blatting far too loud? Is there an insistent whining sound? Take your Cadillac to a service professional before problems arise with your catalytic converter.

If your system is properly maintained and you’ve been hitting every service mark, you should see no issues with your fuel efficiency. If this starts happening, it could be an issue with your muffler.
