The most common cause of engine damage is overheating. There are numerous reasons why your engine may overheat, as well as numerous methods for determining the true cause. We'll look at specific reasons why cars overheat when the A/C is turned on.
This
can be aggravating, so if you notice any of the following symptoms, you must
stop and take immediate action to prevent further damage to your vehicle by
booking a car service in Reading.
What are the signs of a car overheating when the air conditioner is on and the engine is running?
The
symptoms are the same as when a vehicle overheats while the engine is turned
off:
1. Temperature gauge
Every car has a coolant temperature gauge that should not go above 110 degrees Celsius. In addition, instead of the traditional gauge, some vehicles are equipped with a warning temperature lamp. They are designed to turn on and warn you if the engine coolant temperature rises abnormally. The only time these gauges fail is if there is a coolant leak. If this is the case, look for full car service near me and let a trained technician take a look and resolve the issue.
2. Ticking sounds coming from the engine compartment
When engine oil is used beyond the manufacturer's
recommended time, it loses viscosity and thus fails to perform its intended
function. As a result, pats will be left to create friction between them.
3. Engine shut down
Every
modern car has some sort of safety feature that prevents the engine from
starting if it has overheated, regardless of whether the A/C is turned on or
off. The car can now be started after it has cooled down.
What are the causes of the car overheating when it is idle and the A/C is turned on?
So,
you've determined that your car is overheating while idling in traffic with the
A/C on; now let's figure out what's causing the problem:
1. AC compressor overload
As we all know, when we use the A/C, the compressor adds extra strain to the
engine. You can tell by turning on the A/C and noticing a slight increase in
RPM. When a vehicle's cooling system is designed, it is done so in such a way
that it does not interfere with the vehicle's operation. When the compressor
seizes and is no longer allowed to turn by the accessory belt, problems arise.
The car, not knowing this, will continue to try to turn the compressor,
overheating the engine as a result of the additional strain placed on it.
2. Faulty cooling fan
A
faulty cooling fan, cooling motor, or any connectors' controls that activate
the cooling fan could also be the cause of your car overheating when idle and
the AC is turned on. The cooling fan runs at different speeds for different
loads, some cars have two fans and each speed has a different level of load to
cool the engine. As a result, if the fan motor is weak, it will not properly
cool the motor, causing the vehicle to overheat.
3. Inadequate cooling system
The first step in inspecting the cars is to check the cooling fan. The next
step is to inspect the rest of the A/C system, because a properly functioning
cooling system is critical. The cooling system works to cool down the
condenser, which heats up when the air conditioner is turned on. The
condenser's primary function is to convert the cooling gas from a gaseous to a
liquid state. To ensure that this process is carried out correctly, the
radiator should be free of any clogs that may obstruct the flow. Furthermore, a
bad water pump can cause poor heat dissipation, resulting in your engine
overheating with the AC on.
4. Engine coolant sensor failure
As we all know, the device is in charge of signalling the engine control module to turn on the cooling fans. This sensor is located on the cylinder head in the water passages that measure the temperature of the water flowing from the radiator to the engine's internal components. As a result, this sensor could be the cause of engine overheating when the AC is turned on. Because this sensor may not be sending the correct signal to the engine, the control module that is in charge of turning on the fans to the correct speed will not function.
Final Thoughts
As part of your routine maintenance, we recommend that you always check your cooling system. This will keep you from having bigger problems in the future. Heating is the engine's first foe because it can damage internal components. This guide should assist you in resolving the issue, but if you are even slightly perplexed, search online for car service near me and you should seek the advice of a professional.
