How to Identify and Fix Exhaust Leaks
Exhaust leaks are a common but dangerous problem that many Kenyan drivers overlook. A leaking exhaust not only increases emissions but also reduces fuel efficiency and exposes passengers to harmful gases. Knowing how to spot and fix exhaust leaks in Kenya keeps your car safe and roadworthy.
What Is an Exhaust Leak?
An exhaust leak happens when gases escape through cracks, holes, or loose joints in the exhaust system before reaching the tailpipe.
Symptoms of Exhaust Leaks
1. Loud Engine Noise
Exhaust leaks often cause roaring or hissing sounds, especially during acceleration.
2. Reduced Fuel Efficiency
Leaking systems force the engine to work harder, increasing fuel consumption.
3. Vibrations in the Cabin
If you feel unusual vibrations in the steering wheel or pedals, it could be from a leak.
4. Strong Fuel Smell
Escaping fumes create a noticeable smell inside or outside the vehicle.
5. Failed Emissions Test
Exhaust leaks increase harmful gases, leading to failed NTSA inspections.
