Have you ever replaced a radiator cap? It turns out that this radiator cap needs to be replaced periodically. Especially when the rubber valve or its parts are damaged. If damaged, it can affect the radiator's performance in stabilizing your vehicle's engine.

The radiator cap plays an important role in preventing radiator water leaks that can generate high pressure when operating. Have you ever seen the numerical code on the cap? In fact, that part has the meaning of the numerical code of the car's radiator cap.

Let's Find Out the Meaning of the Car Radiator Cap Number Code!

For those of you who do not know the meaning of the car radiator cap number code, there is no need to worry. From now on, you should understand what the meaning of that number code is. When you replace the radiator cap, you will find the number indicated on the bottom or side of the cap.

Generally, the numbers displayed are like 108 kpa (kilopascal) or just the number 1.1. This number indicates the maximum pressure limit that the radiator cap can withstand. The magnitude of this pressure can be calculated in units of bar or kg per cubic centimeter of radiator air volume (kgf/cm2).

The radiator cap will hold the air pressure of the radiator while circulating between the reservoir tank and the radiator. If there is 1 liter passing through the radiator cap, then every cubic centimeter of air circulating between the reservoir and radiator can generate a force of 1.1 kg on your car's radiator cap.

Circulation between the radiator and the reservoir tank can occur when the engine cooling system is working. Later, the water in the radiator will be drawn through the cooling channels in the engine block. When the water flow decreases in the radiator, the radiator will draw reserve water from the reservoir tank to maintain normal levels.

A running vehicle engine can cause the temperature of the water in the radiator to rise. When the temperature matches the number on the radiator cap, the valve will open and release excess pressure into the reservoir tank.

However, you need to remember that not all types of cars have the same radiator cap, considering that each car has different pressure levels. Certainly, the radiator cap used will be adjusted to the car's standard specifications.

Checking the radiator cap on your car should be done periodically to avoid damage. If there are parts that are damaged, replace them immediately with a new one. If you do not replace the radiator cap with a new one promptly.

It could cause the radiator to not work optimally. This can also cause the engine to overheat. Certainly, it can decrease your car's engine performance as well.

Always ensure to replace the radiator cap that matches the pressure number on the cap. Especially now that you know the meaning of the radiator cap number code, you must choose the type of cap according to the pressure number on your car. If it does not match, it can cause the radiator cap to be easily damaged.

Always pay close attention to the number code on the radiator cap so that you do not mistakenly choose a radiator cap that matches the car's specifications. Is this review helpful for you?
