Top 3 Signs of Malfunctioning Exhaust Manifold in
Cars
2
Exhaust manifold is an engine component that is
found in all internal combustion engines and is
usually made of cast iron or stamped steel
designed to collect exhaust gases.
3
The exhaust manifold is attached to the engine
cylinder heads and has ports that collect exhaust
gases from each individual engine cylinder.
4
The materials used in making the exhaust manifold
are designed to withstand high amounts of
pressure and heat required to trap transport
exhaust gases.
5
While they are strong by nature, they are still
prone to issue and can affect the integrity
smooth running of the car.
6
However, a failing exhaust manifold produces some
symptoms which can warn the driver of potential
issues. Here are the following signs exhibited by
the exhaust manifold.
7
Abnormal sounds
8
The first symptoms you will experience is a
problem with the engine exhaust manifold is an
excessively noisy exhaust when the car is running.
9
If the exhaust manifold cracks, breaks, or leaks,
it will cause an exhaust leak that will lead to a
noisy exhaust which will warn you about the
potential problem.
10
Your car will produce a hissing or tapping sound
from the engine bay which will get louder when
the engine is accelerated.
11
Decrease in Efficiency
12
The engine performance issues are another symptom
that can be caused by a malfunctioning exhaust
manifold in your car.
13
If the exhaust manifold cracks or leaks, then it
will cause an exhaust leak which can negatively
affect the engine performance.
14
An exhaust leak can cause the vehicle to
experience a reduction in power, acceleration and
even fuel efficiency.
15
Foul smell from the engine bay
16
One of the most common symptom of an issue with
the exhaust manifold is a foul burning smell from
the engine bay.
17
When the exhaust manifold has an issue with the
heat shield or exhaust leaks, then the excess
heat can damage the nearby electrical and plastic
components.
18
Exhaust manifolds can reach temperatures in
excess of nine hundred degrees Fahrenheit which
can cause any nearby or contacted components to
burn up.
19
Thus, these burnt components produce a foul smell
and can also damage the other parts of your car.
20
Conclusion
21
The exhaust manifolds are one of the strong
components in your car but they are still prone
to issues and can malfunction anytime.
22
If you ever experience any of the
above-mentioned symptoms in your car, then take
your vehicle to an automotive shop to fix the
issue.
