Coolant - The "Lifeblood" of the Engine
When the engine is running, a large amount of heat is generated and needs to be dissipated through the cooling system; otherwise, it will cause fatal damage. Data shows that 40% of engine failures are due to improper maintenance of the cooling system, with the main threats coming from three aspects: metal corrosion, cavitation erosion, and scale deposition. The core function of coolant is not only to prevent freezing but also to cool and dissipate heat, prevent corrosion and rust, prevent boiling and scale formation, and directly determine the engine's lifespan and operational stability. Fleetguard has been deeply involved in the field of heavy-duty diesel engine accessories, and its products are specially designed and developed to meet the demands of harsh working conditions.
What's in the coolant?
Water-based liquid raises the boiling point and lowers the freezing point. Ethylene glycol (EG): The mainstream type in the market, with excellent anti-freezing performance but some toxicity. Propylene glycol (PG): Less used and slightly more expensive, non-toxic, but with weaker low-temperature protection. Additives: Chemical formulas to prevent cylinder liner cavitation, scale formation, and other issues.
Certification and Standards:
Compliant with international authoritative certifications such as SAE J1941 and ASTM D6210, with strong compatibility and reliable quality.
Understanding Fleetguard's "Hardcore Indicators"
Temperature adaptability: Select the freezing point based on the local climate, 10°C lower than the local minimum temperature. Anti-corrosion and anti-rust ability: Through pH value and metal ion control, to prevent corrosion of the cooling system and extend the engine's lifespan. Long-term stability: A super-long service life of 380,000 kilometers or 6,000 engine hours (requires DCA4 maintenance). Compared to the 2-3-year replacement cycle of ordinary coolants, it is more economical.
Should I choose Fleetguard for my equipment?
Core compatibility: Cummins heavy-duty diesel engines, diesel generator sets. Extended scenarios: Other heavy-duty diesel engines, construction machinery, aluminum engine cars/light vehicles, mountainous areas, cold regions, high-temperature and high-load conditions (such as long-distance transportation, power stations), offshore platforms, and other harsh environments.
How to Use Fleetguard Filters Correctly?
Selection tips: Choose the freezing point based on the local temperature. The difference between premixed liquid (ready to use) and concentrated liquid (mix 1:1 with deionized water). Usage taboos: Do not mix with other brands or colors of coolant, do not open the radiator cap when the engine is hot, and avoid direct skin contact. Maintenance points: Regularly check the appearance of the coolant (no sediment, clear and transparent), supplement DCA4 every 20,000 kilometers or 250 working hours, and replace it promptly if it becomes cloudy or has impurities.
Coolant, choose the right product based on your needs, and remember the three key points: inspection, supplementation, and cleaning. Recognize products that meet ASTM D6210/D3306 and Cummins CES14603 standards, and use them in conjunction with slow-release filters to reduce faults and ensure stable engine operation.
