Tempe Auto Repair: Your Car’s Exhaust System: More Than A Muffler
We’ve all heard a car or truck thunder by that needs a new muffler, but there’s actually more to the exhaust system than just the muffler. The exhaust system has three main functions. First, it safely gets the hot exhaust gas from the engine, out through the tailpipe. Second, it treats the exhaust to remove harmful pollutants, and third, it muffles the engine noise What is meant by the fact that it safely moves the exhaust? Exhaust gas is poisonous.
You don’t want it getting into the passenger compartment where you sit. Carbon monoxide can be deadly. That’s why you should never run your engine in a closed garage. Not to be too dramatic, but…if you have a leak somewhere in the exhaust system, it could get into the passenger cabin and make you sick or even be life threatening. It’s pretty serious indeed. If you smell exhaust in the vehicle, roll down your windows and get it inspected. You may smell or see exhaust coming from the engine compartment or under the vehicle, if you have a leak. It’s possible you could hear a leak, too. Sometimes it’s loud and obvious, and sometimes it’s just a ticking sound when you start the engine, that goes away as you drive. That could be a small crack or a bad fitting that leaks when it’s cold, but seals up when the metal heats and expands. You can’t underestimate the safety aspects of an exhaust leak. Now let’s address the environmental issues. Exhaust gas contains a number of pollutants and particulates. The catalytic converter scrubs some of those harmful substances, and diesel vehicles have systems to deal with soot. But, catalytic converters eventually wear out and need to be replaced. They’re expensive, so you want to help them last as long as possible, by keeping the fuel system clean and replacing your air filter. These components need to be tested for function, with an emissions test, from time to time. And that brings us to the muffler. You can actually get a muffler that suits your taste. Some want whisper quiet, others like a little rumble. And some like a roar! If you have ANY doubts about the safety of your exhaust system, give us a call and schedule a free inspection today!
When your vehicle needs maintenance, your first instinct may be to look for the cheapest mechanic around. This is especially true if you’re on a very strict budget and can’t afford to spend a lot of money on car repairs. However, picking the cheapest mechanic or buying the cheapest parts to use may not always be the best thing to do. While there might not always be a reason to buy the most expensive items or go to the most expensive mechanic, don’t always go with the cheapest.
Volvo has always done things a little differently than BMW and Mercedes. Rather than hold back updates and release them all in “mid-cycle refreshes,” Volvo prefers to let the changes dribble out slowly year after year. As a result of this process a car can change significantly over time but it happens so incrementally that to the casual observer it’s still the same car that launched four years ago.
