What are radiators and how do they help keep your car driving smoothly?
by Masashi S. JDM EnthusiastWhen in operation, a car's engine
heats up constantly, and if it reaches a dangerously high temperature, there is
a possibility of a sudden explosion. As a result, it must be cooled to a
reasonable temperature, such as between 80 and 100 degrees Celsius, and this is
where the radiator comes in—it assists in cooling the engine to the proper temperature.
The majority of modern engines are water-cooled.
Water-cooled
Engine Radiator Components
A coolant made of water circulates in
the water jacket around a cylinder in a water-cooled engine to keep it from
overheating. To improve the efficiency of the water pump, a radiator is mounted
in the center between the outlet and inlet. The radiator, radiator hose, water
pump, thermostat, and cooling fan make up the entire system. Cores are a series
of narrow passages that allow coolant to flow through the main body of the
radiator. The goal is to increase the amount of water flowing through each core
to increase the cooling impact. The radiator simply does not work—take let's a
closer look at each portion of the radiator-related parts to better understand
their functions. The radiator's function is fulfilled when these parts are used
together.
The Cooling Fan
The temperature of the engine is
lowered by fresh air when it is operating, but air cooling alone is inadequate
for periods when the engine is not in motion but still producing heat, such as
during traffic jams. As a result, a cooling fan becomes essential. It improves
the cooling performance by increasing the amount of air flow in front of the
radiator to a satisfactory degree.
Water pump that keeps on pumping
The main function of the pump
circulates liquid coolant to the water jackets around the engine, radiator, and
sub tank. This all helps to keep the coolant in the radiator flow smoothly to
the water jackets.
The thermostat aka temp checker
The thermostat helps to maintain the
coolant's permanence within a specified temperature range. It also stops the
flow of water in case of severe cold weather to prevent coolants circulating
inside the radiator. If an engine heats up, then its water temperature increases
and when the coolant temperature is above about 80 degrees Celsius the water
outlet opens up fully, enabling the coolant to circulate.
Maintaining the radiator effectively
Step 1. Check the coolant routinely
One of the main causes of the engine
overheating is the water level of the coolant decreasing, or the water getting
dirty with rust. Every two years, we recommend changing the liquid coolant.
Let's wash them out with a radiator cleaner when the rust and water scale are
in a bad condition.
Step 2. Check the fan belt
By hand, you can check the tension of
a fan belt that drives a cooling fan. If you can force the center of the fan
belt down to between 13 and 20 mm with your thumb, the current tension of the
belt is fine. When the rubber component of the fan is weakened to the point
that it melts and falls, the fan's turn cycle is jeopardized, which can lead to
overheating, and it should be replaced.
Step 3. Check the radiator hose
Any gaps, slacks, or distortion in the
radiator hose will result in water leakage, so it's a good idea to check the
hose's condition on a regular basis to avoid any unnecessary accidents.
As with any product, upgrades and
improvements are made over time through the new iterations.
