Maintaining the condition of an exhaust system is necessary for fuel efficiency. Now, as a repairman, if a customer brings a car in with a system of exhaust problem, make sure you properly evaluate the whole exhaust system prior to starting the repair. Examining the exhaust system for indications of early failure assures that all essential repairs are made, rather than just the issue that was brought by the client into your shop in the first place.
From checking for leaks to evaluating the converter of a catalytic, know the basics of inspecting the exhaust system.
Exhaust Leaks Must Be Inspected
Visible and audible leaks are the two forms of leaks. Check the vehicle’s undercarriage for any visible leaks. Keep in mind the following points:
- Breaks, cracks, and corrosion in the welds should be looked for.
- Check for misalignment or gaskets that have been burned at the pipe connectors.
- Check for leaks by clamping connections.
- Check for leaks in flex pipe, as this is commonplace for failure.
Take the car for a road test and observe any odd noise generated by the exhaust system to see any audible leaks. It’s a good idea to look for exhaust gas smells in the vehicle’s interior while you’re driving.
Any exhaust system leaks should be fixed.
Damaged Parts Must Be Replaced
Examine the isolators and hangers for signs of wear, as well as any loose, broken, or pieces that are missing. Any broken or malfunctioning goods should be replaced. All of your exhaust components, including the downpipe, front pipe, exhaust manifold, muffler, and catalytic converter, will be in good working order if you do routine exhaust system maintenance.
Invest in a high-performing exhaust system. Just as in Australia, many exhaust system services deliver the best quality of service. For example, the Manta Performance Exhaust Systems Australia is known as it delivers quality Australian-built performance exhausts to enthusiasts worldwide.
Blockages Are Required To Be Checked
Perform a vacuum or back pressure test on the engine to look for obstructions in the exhaust system. Connect the vacuum to the exhaust tailpipe using the cleaner hose. The gases depart the car at the end of the exhaust system. Ensure that the vacuum cleaner draws air through the exhaust system by turning it on.
Examining The Catalytic Converter
Except in older automobiles, catalytic converters rarely fail, but they can create significant difficulties when they do. The converter is a ceramic plating block. Take a look at the catalytic converter. Make sure to do the following prior to changing the catalytic converter:
- It is necessary to extract and repair any trouble codes for PCM.
- Look for (TSB) Technical Service Bulletins or upgrades in the PCM.
Catalytic converter servicing may entail repair or replacement, depending on the amount of the damage. It’s also worth mentioning that a broken catalytic converter is generally always the result of another vehicle issue that has to be addressed. A good catalytic converter service will replace the item and inspect the rest of your vehicle to figure out what caused the issue.
Check The Fuel Control System
As a result of a faulty exhaust system, your fuel efficiency may drop. If you’re not getting the fuel efficiency you’re used to.
It’s advisable to check your exhaust system. Ensure that the automobile is closed-loop and has correct fuel control and operating temperature. Check the oxygen sensors next. Under typical operating circumstances, the oxygen sensor in front should be about 450MV, including the rear oxygen sensor must be between 650MV and 850MV.
Contamination Check
Check for any fluids or coolants of the exhaust that could lead to rapid failure or wear. A little piece of tape or blue tack can be used to plug a leak once it’s been found temporarily. This will allow you to look for further leaks throughout the system. Keep in mind to remove any temporary measures you’ve installed on the exhaust system before starting the car again.
Choose The Appropriate Catalytic Converter
The catalytic converter is the second stop for your engine’s emissions, where harmful nitrous oxide, carbon monoxide, and hydrocarbons are turned to carbon dioxide and water. Because the catalytic converter’s primary function is to reduce pollution, your automobile is unlikely to pass emission standards if it isn’t working correctly.
When choosing a catalytic converter replacement, keep in mind the emission rating. Some cats are legal in 47 states, but not in California or other states with stricter emission standards.
Final Thoughts
When you’re traveling down the road, and a stealthy automobile sneaks up behind you, you’ll know it’s a very fine-tuned exhaust system doing its thing! On the contrary, if you hear a loud car or, even worse, that loud vehicle is yours, it’s time to have it examined by a trained professional.
A malfunctioning exhaust system can cause a check engine light to be illuminated, foul odours, and insufficient fuel economy in vehicles. You can avoid having any difficulties with your exhaust system by getting it tested every year or two, regardless of whether you’ve observed a problem. Make an appointment right immediately to have your exhaust system repaired!
