RADIATOR CAP
The material of the pressure valve uses a silicon rubber. Silicon rubber has the characteristic of being resistant to heat.
It has higher temperature durability of 100℃ and more than other synthetic rubbers such as NBR and EPDM which were conventionally used.
It also has high resistance to chemical substances and does not change for a long time even against chemicals such as LLC which exist in the radiator.
In addition, since we are all of the parts procurement and manufacturing processes in Japan, it is a high-quality products.
Currently, RADIATOR-CAP is produced overseas even genuine parts, there is almost no thing of made in Japan.
It is a commodity that is trusted by customers of Japanese-made safe and secure.
Why to Replace a Radiator Cap
While a simple component of your cooling system, your radiator cap plays a crucial role in maintaining your vehicle’s cooling efficiency. Radiator caps are cheap, easy to find and take only a few seconds to replace, but ignoring a faulty one can cause overheating problems and potential engine damage, especially during the hot summer months.
A radiator cap generally contains a spring loaded plunger, and this plunger serves two purposes in your cooling system.
First, should internal pressures exceed the spring pressure of the plunger, coolant will be diverted to an overflow reservoir.
This is important because if this simple feature did not exist, pressure would simply continue to build, causing sudden leaks or even explosions as the building pressure desperately tries to find a way to relieve itself. Second, this spring pressure helps to maintain a specific pressure inside your cooling system. As atmospheric pressure rises, the boiling point of a fluid also rises. Boiling fluid isn’t very good at transferring heat, so by increasing the pressure inside the system, you increase the amount of heat the cooling system can remove before it begins to boil.
Replacement Tips
Replacing the cap on your radiator is an easy thing to do and may only require a few seconds of your time. It is extremely important to always make sure to allow the engine to cool down before removing the radiator cap, as removing the cap from a hot system can cause sudden coolant spray and severe burns. Pay close attention to the pressure rating on your cap, and select one with the same pressure rating. Once you have a replacement and your engine is cool, simply unscrew the old cap, and install the new by screwing it on.
A faulty radiator cap can have a huge impact on the cooling performance of your vehicle. If your coolant is boiling at even normal temperatures, or you seem to be having problems with your coolant moving back and forth between the cooling system and your overflow tank, consider taking a look at your radiator cap. Replacements are cheap and easy to obtain and can sometimes be the simplest solution to radiator overheating problems. While a cap may be easy to replace however, it is not a substitute for proper radiator maintenance. Proper coolant changes and cleaning are key components to a healthy cooling system.
