Heating And Cooling Systems: How To Keep Your Car Temperature Correct
For your car to perform at its best, you have to ensure that the car's internal temperature is at the ideal level. If the temperature is too hot or too cold, your car's engine will stop working or work poorly. This means that in summer, the car needs to be cooled, and in winter, the car has to keep warm.
For this to happen, the car has a heating and cooling system, but ensuring this system works properly depends entirely on you. In this article, we will teach you the proper method for taking care of your car's heating and cooling system so that regardless of the external temperature, your car will perform at its best.
The Cooling System
The car has a cooling system designed to ensure that your engine doesn't heat up. If the engine heats up, it is highly likely to seize. A seized engine requires a lot ao repair work and can turn into a costly affair.
Let's look at what components make up this cooling system that prevents the engine from seizing.
Parts Of The Cooling System
The cooling system of most vehicles consists of the following components:
- Electric cooling fan
- Water pump
- Radiator top hose
- Radiator bottom hose
- Thermo-time switch
The radiator is the most important component of the car's cooling system. As the engine's temperature rises, the radiator is responsible for transferring this heat to the air surrounding the radiator fins. This transfer of heat is made possible through the use of coolant.
Coolant is a special liquid that absorbs the heat produced by the engine and brings it to the radiator, where this heat is transferred into the air.
Inside the radiator is a cooling fan that sucks air into the radiator; this air circulates in the radiator fins where the coolant and air meet so the heat can be transferred. This process is highly dependent on the coolant.
The first step in maintaining your cooling system is ensuring your radiator has the right amount of coolant. In summers, you will have to keep a close eye on your coolant levels. If the coolant isn’t at the right level, your engine will heat up and may even seize.
If you want to fill the radiator tank with water instead of coolant, then use pure water and not tap water. Tap water has many impurities and dirt that can damage the cooling system.
Another important factor for radiator maintenance is flushing. Radiator flushing is important because it removes old coolant, dirt, and residues left in the cooling system. When flushing the radio, use the best radiator flush to ensure proper cleaning of the entire cooling system.
The cooling system is comprised of hoses. These hoses tend to become brittle over time, and cracks begin to form, leading to coolant leakage. It is important to examine these hoses from time to time and replace them if you notice a crack.
Electric Cooling Fan
The cooling fan is designed to suck air in towards the radiator. This is done so there is enough air around the fins to transfer heat from the coolant. If the cooling fan is not functioning, your radiator will not be able to cool the engine, leading to an episode of overheating.
The thermostat is another important component of the cooling system. The thermostat is responsible for the amount of coolant that reaches the engine.
Two problems can occur with the thermostat; it can either be stuck-closed or stuck-open. If the thermostat is stuck open, the engine will receive coolant regardless of the external and internal temperatures.
This will lead to increased fuel consumption and inefficient engine function because the engine wouldn’t be able to get warm enough to perform at its optimal level.
If the thermostat is stuck closed, your engine will not cool down in time because coolant wouldn’t reach the engine and engine block. This lack of coolant will lead to overheating and seizing of the engine.
In either case, you will have to get your car checked by a mechanic, but this problem should be addressed immediately to avoid damage to the engine.
The water pump is responsible for keeping the coolant moving. It sends the coolant to the engine, engine block, and back to the radiator. If your water pump is faulty, you will hear a grinding noise. This indicates that the bearings in the pump have worn out. The best solution for this problem is to replace the water pump.
The Heating System
Wintertime can be harsh on your vehicle’s engine, so a well-functioning radiator and heating system are essential.
Some common problems that you can face with the heating system of the car are:
- Fluid can freeze in the cooling system and cause blockage, resulting in the system rupturing
- Water can freeze inside the radiator, causing the casing to crack and leak fluid
- A cracked radiator casing will lead to fluid leakage, contaminating the transmission fluid
The first step in preventing these problems is by using antifreeze. Antifreeze needs to be added to the water in the cooling system to prevent it from freezing. Antifreeze ensures that the water doesn't freeze even in temperatures as low as -30 degrees Celsius.
It is important to note that a 50/50 antifreeze to water ratio is recommended.
Apart from using antifreeze, regularly checking the heating system's hoses is important. Hoses tend to crack during winters due to contraction. Replacing a hose in time will prevent the loss of coolant in the system.
Like we have mentioned above, the thermostat will also play an important role in keeping the engine warm during winters. It will do so by controlling the amount of coolant reaching the engine.
We hope this article has helped you understand how important your car's cooling and heating system is. Maintaining this system is easy and can be done by anyone at home. Just make sure always to keep your coolant at the right level, and keep an eye out for unusual engine performance or overheating episodes.
