The date of manufacture can be checked with the LOT number. The LOT number is provided as YYMMDD or YYYYMMDD.

Store in a cool and shady place.

In principle, use it immediately after it is opened. It is because the product may deteriorate due to inflow of foreign substances and air.

Water-repellent windshield washer fluid may become cloudy when mixed with a general windshield washer fluid.

Please use it after exhausting all existing products so as not to mix them.

It is OK to use DOT-4 instead of DOT-3. DOT-4 has a higher boiling point and an excellent corrosion prevention ability compared to DOT-3.

However, if the existing DOT-3 is partially mixed with DOT-4 brake fluid for use, the performance of the DOT-4 brake fluid cannot be fully exhibited,

so it is recommended to inject the DOT-4 product after completely removing the existing product.

DOT-4LV is a high-performance product with a higher boiling point and lower kinematic viscosity at low temperatures compared to DOT-4 products.

The high boiling point of brake fluid prevents the vapor lock phenomenon.

In addition, if the kinematic viscosity is low, more efficient operation is possible in electronic control safety systems (ESP, EPS, ABS, etc.),

delivering a fast and precise braking force by preventing uneven braking.

As a potable moisture analyzer is a device that estimates the moisture content by measuring electrical conductivity,

it is difficult to accurately measure moisture, and there can be a difference in moisture between the moisture measured by a portable moisture analyzer and the actual brake fluid.

As more water can flow into the auxiliary brake fluid tank when it is opened, it is recommended to replace the brake fluid after 2 years or 40,000 km.

Unlike internal combustion engine antifreeze, the electric vehicle coolant must not be diluted with water. Please inject the undiluted product into the vehicle.

The fuel cell stack coolant is a product designed to manage the heat generated from the hydrogen electric vehicle stack,

and has different requirements from those of the coolant used in electric vehicles. As the products have been developed for the specific systems,

it is recommended to use it according to the vehicle manual.

Battery coolant is a product that manages heat generated from batteries, etc., and antifreeze is a liquid that manages heat generated from the engine.

As the specifications required for each system are set differently, it is recommended to use it according to the car manual.
