To perform its job properly, the car's AC system consists of various components that work together for optimal results.
But do you know the functions of each car's AC component and what parts make up the system? Let’s take a closer look!
The first component in a car AC system is the compressor, which pumps freon gas so it can circulate to other AC parts.
In addition, the compressor compresses the refrigerant, changing it from a gas into liquid form.
The AC compressor is divided into two sections that both work to pump refrigerant toward the condenser. The first one is the suction line (low pressure), connecting the refrigerant from the evaporator, and the discharge line (high pressure), connecting the refrigerant to the condenser.
The next car's AC component is the condenser, which helps regulate the AC temperature inside the car.
The condenser works by releasing heat from the freon, which is then cooled down with the help of the cooling fan.
The next and most familiar component in car AC is freon, a chemical refrigerant that absorbs heat from the cabin air and releases it outside.
Because of this function, if your car's AC no longer blows cold air, one of the possible causes is low or empty freon.
The receiver dryer filters dirt and moisture from the AC system. It is located between the condenser and the expansion valve.
This component helps protect the AC system from issues such as clogged expansion valves or compressor corrosion, which can reduce the overall performance of the AC.
The expansion valve changes liquid freon into gas through a spraying process.
This process makes the refrigerant colder before it flows into the evaporator to absorb heat and produce cool air inside the car cabin.
The evaporator plays a vital role in cooling. Its main job is to absorb heat inside the cabin and convert it into cool air.
Sometimes referred to as the AC filter, the refrigerant in the evaporator is cooled first before it flows into the cabin to provide cold air.
The cooling fan helps lower the condenser’s temperature by blowing air over it. This process cools the freon more effectively, making the AC system more efficient.
Without the cooling fan, the freon would not cool properly, the AC system would be less effective, and its performance could drop significantly.
The magnetic clutch in a car's AC is an electrical component that stops the freon pressure when it gets too high.
Even though the engine pulley keeps spinning, the magnetic clutch controls when the compressor turns on and off.
When the compressor is active, freon pressure rises, especially when the engine is revved.
The magnetic clutch uses magnetic force to connect or disconnect the compressor pulley and shaft, protecting the AC system from damage.
In addition to the car AC components above, there are some other important components as well, including the thermistor, high-pressure hose, low-pressure hose, blower, pressure switch, relay, and cabin filter.

When driving on the road, traffic signs play a crucial role in keeping drivers and pedestrians safe and orderly.
These signs use various symbols, letters, and numbers to provide warnings, prohibitions, instructions, or directions that are easy to recognize for all road users.
In Indonesia, traffic signs are regulated under Minister of Transportation Regulation No. 13 of 2014, ensuring that all parties properly apply their functions.
To help you understand better, here are 7 traffic signs and their meanings that every driver should know!
The stop sign is one of the most common traffic signs, typically displayed with a red background and the word "STOP" at the top.
This sign indicates that drivers must come to a complete stop and are not allowed to proceed until the road is safe. The purpose is to prevent potential traffic conflicts or accidents.
A red circle with a horizontal white stripe symbolizes the No Entry sign. It indicates that vehicles or pedestrians are not allowed to enter a particular area.
However, certain exceptions may apply to authorized parties as specified by local regulations.
A white background with the letter "S" crossed by a red line is used to indicate that stopping is not allowed.
If you see this sign, it means you cannot stop your vehicle at all, even for a short moment. Violating this rule may result in a traffic ticket based on Indonesia’s traffic law.
The No Parking sign is displayed as a large letter “P” with a red slash across it.
When this sign is placed on the road, it means vehicles cannot be parked or stopped in that area.
This sign typically has a white background with a red border and a picture of a vehicle crossed out.
If the symbol depicts a car, motorcycle, or truck, it indicates that vehicles of that specific type are not permitted to pass through the road.
For example, heavy trucks are often prohibited from entering residential areas.
The yellow triangle sign with a curved arrow warns drivers of a sharp turn, either to the left or right.
It serves as a reminder to slow down and drive carefully to avoid accidents. The signs are commonly found in hilly areas, mountain roads, or near residential zones.
A blue rectangular sign with a bridge symbol indicates that there is a bridge ahead.
Drivers are advised to reduce their speed and stay alert, as not all bridges are large or in perfect condition. Some may even have specific load restrictions that vehicles must follow.
The yellow triangular sign with a steep slope symbol warns drivers that a steep downhill road is coming.
Drivers should slow down and shift to a lower gear. This sign is usually found in mountainous or hilly regions. Before passing a steep descent, it’s essential to check your brakes to avoid brake failure.

Exercise is a physical activity that is extremely popular worldwide, including in Indonesia. In addition to improving physical health, exercise often becomes a pathway for talented individuals to achieve accomplishments at professional or competitive levels.
However, exercise is different from general physical activity. Physical activity typically refers to any movement that requires muscle contraction and results in energy expenditure.
Examples of daily physical activities include climbing stairs, gardening, and doing household chores.
Exercise, on the other hand, is a specific form of physical activity that is planned, structured, and performed intentionally intending to improve or maintain physical fitness and overall health.
Common examples of exercise include aerobics, swimming, football, cycling, and many other sports.
To better understand what exercise is and the benefits it provides for the human body, read the explanation below.
There are several indicators that your car's remote battery is running low, such as a dim or dead indicator of light, shorter range, and more.
In most cases, you can replace it yourself by following the vehicle’s manual. You can also check the code on the old battery to ensure you buy the right replacement.
The most common types of car remote batteries are CR2032, CR2025, and CR 2016.
To help you recognize the warning signs that your car's remote battery is weakening or about to run out, here are the main indicators you should know!
The most common sign your car's remote battery is dying is when the remote buttons start becoming unresponsive, where you need to press them multiple times before the car responds. This indicates that the battery is already running low.
Normally, a car remote signal can reach from 5 to 20 meters, and on some car models, it can even work up to 30 to 50 meters.
If your vehicle only responds when you are very close, it could be a strong indicator that the remote battery is weak or nearly dead.
Another sign of a weak car remote battery is when you have to press the buttons several times before it works.
This happens because the power is not strong enough to send a proper signal to the vehicle, so the buttons need to be pressed more than once.
Some car remotes come with a small LED light. If the battery is weak, this indicator light will become dim or stop lighting up entirely when pressed, showing that the power inside is already drained.
If this happens, it’s best to replace the battery immediately with a new one that matches the specifications to restore your car’s remote function.
After learning about the signs, you also need to know the right steps to replace the car remote battery. Here’s how:
Prepare the tools, such as a small screwdriver, tweezers, or a thin pocket knife, if needed to open the remote cover.
Open the remote cover and use the prepared tools carefully. Some remotes may have screws that need to be removed first.
Remove the old battery. Carefully take out the battery using tweezers.
Insert the new battery, check the manual, and insert the replacement battery according to the recommended type and direction.
Close the remote casing after installation, close the casing, and make sure everything is securely in place.
Those are the key signs of a weak car remote battery and the proper steps to replace it. Ideally, once you notice the early signs of a weak battery, you should replace it right away to ensure your car's remote works optimally.
Avoid waiting until the battery is completely dead, as this can disrupt your daily activities and mobility.
Hopefully, this guide helps you keep your car's remote functioning at its best!
