Kobelco Construction Machinery: Cliff-like cooling attack, excavator antifreeze maintenance must not be ignored!

Summary of hot spots in this issue

Antifreeze is a coolant with special additives.，Primarily for liquid-cooled engine cooling systems，It can prevent freezing in winter，Boil proof in summer，Prevent scale all year round、Anti-corrosion and other excellent performance。Antifreeze circulates in the cooling system，Absorb the heat generated by the engine，Heat is given off through the radiator.，This prevents the engine from overheating。

Current period，What we bring to you is the pure Kobelco antifreeze tailored for Kobelco Excavators.，The appearance color of Kobelco pure antifreeze is blue-green.！

*Part designation：SCOOLANT04L  Applicable model：All models
 

Work procedure when replacing the antifreeze

We recommend to change the antifreeze of the water tank and the secondary water tank every 2000 hours，Pay attention when replacing：

1、Drain the antifreeze from the water tank and the auxiliary water tank when the machine is cold.；

2、When filling antifreeze，Fill slowly，Injection rate approx. 10L/min；

3、Fill the auxiliary water tank with antifreeze，Add toFULLScribe；

4、Fill the main water tank with antifreeze，Fill to full level（Under the nozzle 10mm）；

5、Start the engine and stop it after running for about 50 seconds.，Check for leakage of antifreeze，Fill the main water tank to the full level.；

6、Engine running at medium speed，The water temperature is required to reach 75°CAbove，Leave the thermostat switch open；

7、Stop the engine，Confirm again the amount of antifreeze in the main and auxiliary water tanks，Antifreeze must be added to the water tank when it is insufficient.。

*Notice：Open the water tank cover slowly.，Avoid scalding！Cover with cotton cloth and plastic bag，Bare-handed operation is prohibited！

Kobelco pure antifreeze

Six advantages

High quality antifreeze can prolong the service life of the engine.，So what are the characteristics of good antifreeze?？Let's take a look at Kobelco's pure antifreeze.Exclusive advantageCome on！

1. Boiling-proof

    High boiling point of pure antifreeze of Kobelco，Ffectively prevent engine“Boil the pot”，Protect the cylinder block and radiator from high temperatures。Enhance the cooling effect and operation stability of the engine，Extend the life of the machine。

2. Antifreeze

    Kobelco pure antifreeze is made of high-quality antifreeze raw material ethylene glycol.，The dilution concentration is moderate，Wide applicable temperature range。Effectively prevent freezing，Avoid damage to the cylinder block and the radiator due to freezing and expansion。

3. Anti-corrosion

    Kobelco pure antifreeze is formulated with high-quality corrosion inhibitor.，Prevent corrosion problems such as cavitation and rust，Control of scale formation，Avoid perforation of the cylinder block and radiator、Blockage，Ensure the normal operation of the cooling system。

4. Convenience of use

    The pure antifreeze of Kobelco is added with high quality defoamer.，Ensure low foaming of antifreeze，The addition amount can be clearly judged，Avoid influence of heat dissipation due to insufficient addition。At the same time, the dye is added，While not affecting performance，Effectively distinguish the types of antifreeze，Thereby preventing misuse。
