When travelling at slower speeds or at a standstill, the radiator fan keeps the car from overheating. Here's how to identify a malfunctioning radiator fan.
To
prevent a potential MOT test failure, these faults must be resolved before
scheduling your next MOT
testing service.
We
go over the primary signs of a malfunctioning radiator fan and examine its
function. Let's quickly review the warning indicators to watch for.
If
your car is overheating, book an appointment with a qualified mechanic
immediately by searching online for car garages in
Reading. The most common indication of a failing radiator fan is a
heated vehicle engine. You may also notice that the A/C isn't functioning as well
as it usually does and occasionally hear spinning noises coming from the engine
area.
The
following is a more thorough list of the most typical signs of a failing
radiator fan:
1. Fan Isn't Turning On - The
radiator fan's most typical sign of trouble is when it stops functioning. The
motor can fail or burn up occasionally. Sometimes the relay stops functioning.
In either case, if the fan system won't operate, something is wrong. If this
situation is allowed to worsen, more serious problems will develop. As soon as
you realise the radiator fans are not functioning properly, look online for garages in Reading
and make an appointment for a mechanic to examine and fix the problem. This
will help you avoid having to budget for a significant repair bill.
2. Blown Radiator Fan Fuse -
Radiator fan fuse blowing is another cause of the fan ceasing to function.
Because it is failing and using too much amperage, radiator fans can blow a
fuse. To protect the system from this excess power when the electric motor
surges, the fuses break. Although you can replace the fuse, a broken fan will
probably also blow another one.
3. Overheating of the Vehicle
- The fan is in charge of maintaining the proper temperature of the coolant.
Temperatures in the engine will start to rise if the fan is failing. The fan
shouldn't operate until the temperature reaches a particular level, but it
doesn't. When the temperature indicator appears on the dashboard, many times
the driver is not aware that the engine is overheating. You must now turn off
the engine and wait for it to cool down or you risk doing irreparable harm. The
MOT history
checker indicates that an overheating engine is frequently the blame
for a MOT test failing.
4. Poor A/C Performance - If
the radiator fan stops operating, the air conditioning system may not perform
well. The condenser fan's primary function is to remove heat from the
refrigerant by drawing air through it. In fact, compared to the condenser fan,
it generates twice as much air. Not only does the engine get hotter when the radiator
fan is broken, but also the interior of the car. What appears to be an issue
with the air conditioner may actually be a radiator fan problem.
5. Whirling Sounds: Unusual
sounds should raise a red flag. A whirring noise or a loud clicking sound may
be produced when the radiator cooling fan motor starts to fail. These noises
may also be heard if a damaged fan blade starts contacting other parts of the
system. At least you know the fan is still operating, even if it is only
partially. But before it causes other issues, it's best to have this fixed.
The Role of Radiator Fans
To
cool the engine, the radiator fan draws air through the radiator. When air
isn't being forced through the system naturally, such when a car is stopped or
moving slowly, it is intensively utilised. The temperature of the coolant rises
when the engine is running. The engine begins to overheat if there is no
airflow through the radiator to cool it down. Electric motors built into the
fans power this process.
The
motor for the electric fan operates similarly to the majority of industrial
motors. It is a part of the assembly that can be replaced or repaired. But
because it has moving parts, it might wear out over time and malfunction. A
faulty radiator fan may occasionally be brought on by the engine driving it
rather than the fan itself. It will be necessary to conduct a thorough
inspection to identify the malfunction's root cause.
Where is the Radiator Fan?
Direct
mounting is used for the radiator cooling fan on the radiator. A radiator
cooling fan is standard on all recent models of vehicles.
A
radiator cooling fan may be accompanied by additional fans in some vehicles.
One could stop working, but the other could still function.
