Understanding Exhaust System Repair

Auto service technicianRecent graduates of mechanic colleges can understand the importance of maintaining a well-functioning exhaust system. The exhaust piping system in a vehicle is used to collect and convert the gases emitted by the engine and then release them through the tailpipe. The system has three key functions: keeping harmful gases from entering your vehicle, working to reduce the amount of harmful gases produced and reducing the noise that an engine makes. Just like all of the other components in your car, the exhaust system requires upkeep and maintenance to avoid permanent harm. One of the most common exhaust problems is a leak—this can cause a lot of noise, smoke, and smog, so it’s important to rectify the issue immediately. Here are some of the essential steps that someone with auto technician training would take to repair a leaky exhaust pipe.

Locating the Problem

The leak has to be coming from somewhere and it’ll be impossible to repair until the hole or crack is found. After an auto service technician has done all the necessary prepping like making sure the engine has cooled and jacking up the car, he or she must locate the source of the problem. Removing the hole can be tricky because when cutting off a small section of the pipe, precision is crucial to ensure that the pipe can be easily pieced back together.

Putting the Pieces Back Together

An inner exhaust sleeve has to be inserted between the two pieces of the pipe that was just cut. A mechanic inserts the sleeve into both pieces of the pipe while pushing them together until they meet. Here’s how they test whether a clean, straight cut has been achieved when removing the hole—the two pieces should be flush so the outer sleeve can be properly attached. Once the outer sleeve is attached and secured with bolts, the only thing left to do is wrap the pipe in muffler tape so the engine stays quieter.

Signs that Your Engine May have a Problem

Since most auto-owners have limited experience in car repair, it’s always best to let a professional handle any technical issues that arise; however, being able to at least recognize that your vehicle is in trouble is a very useful skill for laypeople to have – particularly when it comes to a leaky exhaust. While the smell of fumes can be an indication of an exhaust leak, a deep rumbling sound can also signify the need for a new muffler. Another telltale sign is a steady decrease in fuel efficiency. It’s important to take your car into an automotive repair facility if you’ve noticed any of these warning signs!
