Symptoms of a Failing Exhaust Resonator
At MyMechanic, we help drivers in Malaysia identify and resolve exhaust issues promptly. A defective exhaust resonator can cause more than just noise—it can affect your car’s performance, prevent it from starting, and even pose health risks. Here are some common symptoms of a failing exhaust resonator:
Symptoms of a Failing Exhaust Resonator
- Reduced Engine Performance and Fuel Economy: A collapsed resonator restricts airflow, leading to decreased power and poor fuel efficiency.
- Check Engine Light Illuminated: In some cases, a collapsed resonator can impact performance enough to trigger the check engine light.
- Engine Stalling or Failure to Start: A severely damaged resonator may create excessive back-pressure, causing the engine to stall or fail to start. This can also lead to incorrect oxygen sensor readings.
- Excessive Noise: A damaged resonator can produce an unusual high-frequency buzzing or other unwanted noise from your vehicle’s exhaust system.
- Unusual Smell: Leaks in the resonator may allow harmful fumes to escape, causing an unpleasant odor and posing a potential health hazard.
Why Exhaust Resonators Fail
Exhaust systems endure extreme conditions, including temperature fluctuations and exposure to corrosive materials. While modern vehicles use durable nickel-steel alloys, resonators are not immune to wear and tear. Inspecting exhaust hangers and motor mounts can help prevent premature failure.
How to Fix a Faulty Resonator
If you suspect an issue with your exhaust resonator, schedule a professional diagnosis at MyMechanic. Our experts will thoroughly inspect your exhaust system for leaks and damage.
Replacing a resonator often requires specialized tools and skills, including cutting out the old unit and welding in a new one. At MyMechanic, we provide professional repair services to ensure the job is done right.
What Does a Resonator Do?
Many drivers may not know the difference between a resonator and a muffler. While both are part of the exhaust system, they serve distinct purposes:
- Resonator: Cancels specific sound frequencies created by the engine, creating a smoother and more pleasant exhaust tone.
- Muffler: Reduces overall engine noise using sound-deadening materials and baffles.
On most modern vehicles, the resonator and muffler are integrated into one assembly for efficiency.
