Exhaust leaks are not only bothersome, but they can also result in diminished vehicle performance, increased fuel usage, and even severe health hazards. It is essential to understand vehicle exhaust leak detection and repair to maintain your vehicle’s efficiency and safety. Auto Parts North Inc. For that reason, we put together this guide to walk you through the process.
Signs of an Exhaust Leak
Spotting an exhaust leak before it becomes a problem will help you to save time and money. The common symptoms to watch for are:
Loud Engine Noise: The most common sign of an exhaust leak is louder-than-usual engine noise, significantly when accelerating.
Reduced Gas Mileage: Are you tanking up more often? A leak in your exhaust system could be the culprit.
Strong Exhaust Odor: A strong smell of exhaust inside your car can be a sign of a leak.
Visible Damage: Cracks, holes, or rust spots on the exhaust system can usually be identified during a visual inspection.
Check Engine Light: On newer cars, an exhaust leak can illuminate the check engine light, particularly if it affects oxygen sensor readings.
Tools You’ll Need
To detect and repair exhaust leaks, gather the following tools and materials:
- Jack and Jack stands
- Flashlight
- Soap and water solution
- Exhaust repair kit (patches, clamps, or sealant)
- Wire brush
- Gloves and safety glasses
Locating the Leak
Ensure your vehicle is parked on a flat surface and the engine is cool before beginning.
Give it a Visual Inspection: With a flashlight, look over the exhaust system — manifold, pipes, muffler, catalytic converter — checking for visible damage.
Do the Soap and Water Test: Start the engine and allow it to idle. Apply a soapy water solution to the exhaust system. Bubbles should form, which means exhaust gases are escaping.
Listen for Hissing or Tapping Sounds: A leak usually makes a characteristic noise that can help you locate it.
Repairing the Leak
There are varying repair methods based on the severity of the leak:
Small Holes or Cracks
Trim the Area: Wire brush away rust and debris in the leaking area.
Exhaust Sealant Application: Apply a heat-resistant exhaust sealant to the hole and allow it to cure according to the product guidelines.
Medium-Sized Leaks
Apply an Exhaust Patch: If the leak is more significant, use an exhaust patch on the damaged section. Clamp it down if necessary to hold it in place.
Severe Damage
Repair the Damaged Area: If the exhaust pipe or muffler is critically damaged, the only solution is to replace the affected part. At Auto Parts North Inc., we have a variety of premium aftermarket auto parts from which you can select.
When to Get Professional Help
Some leaks might be small enough to handle at home, but other cases will need to be handled by a pro. If you do, contact a trusted mechanic:
- Some leaks are closer to the manifold or the catalytic converter.
- You’re a little worried about how much damage is done.
- You have had it repaired, but the problem continues.
How to Prevent Exhaust Leaks in the Future
- Acting proactively against leaks can prevent expensive repairs later on:
- Check your exhaust system regularly for rust and damage.
- Avoid driving on terrains that are too harsh for the exhaust parts.
- Only use quality fuel and quality parts for your system to last.
