What are the Symptoms Behind the Idler Pulley
Noise
2
The engine of your car consists of the drive
belts which is used to run various accessories
that reconnected to it.
3
To control the drive belts, every car has an
idler pulley used to route the drive belts
properly around these accessories.
4
It can also keep the engine from rotating it
smoothly and ultimately sustain the entire
internal function of the car.
5
In most of the modern cars, there is more than
one idler pulley is available for the engine.
6
When the idler pulley for your car worn out or
damaged, then you will notice the following types
of symptoms in your car.
7
Visibly worn out the pulley
8
The first common symptoms of noise behind the
idler pulley is the visible worn out or the old
pulley.
9
When the idler pulley constantly spinning with
the drive belt will eventually wear out both the
components.
10
It may develop the visible scoring marks and
scuffs on the surface of the pulley and at the
end of the day it connects with the belt.
11
Eventually the pully and the belt will wear out
and lead to the belt slipping. As a result, it
will begin the noise at this point.
12
Slippage and squealing noise
13
Due to the worn out of idler pulley may cause
slippage issues in your car because it will bind
and rub against the engine belt.
14
As a result, the idler pulley is created
squealing sound from the engine belts and
eventually worsen the pulley until the pulley is
replaced.
15
In some cases the bad pulley may slip or bind as
well as cause the belt to squeal when you start
the engine.
16
If you neglect the squealing noises, then it will
wear and damage the other belts and components
within the engine.
17
Damage the bearing of a pulley
18
Another visible symptoms of idler pulley are the
ultimate breaks and damage of the pulley and the
belt in altogether.
19
The bearing of the pulley may wear out to the
point of cracking and coming apart from seizing
at a time.
20
It can eventually affect the rotation of the belt
and that can lead to some sort of problems like
stalling and overheating.
21
On the top if it, you will even hear a louder
squealing noise which will be consistent and
annoying to everyone in the car and the surround
areas.
22
Final words
23
Most of the ideal pulley are eventually require
replacement on the majority of the road going
especially in high mileage cars.
24
As it is very important for the overall operation
of the engine and allow the engine to function
properly after it has been started.
25
If you suspect that the idler pulley of your car
has any issues, then inspect your car by a
professional technician.
