Maintenance Parts/Coolants

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized coolants within our maintenance parts catalog to support diverse heavy-duty equipment. Our product lineup covers a broad range of machine series and fluid thermal configurations, ensuring that every component meets rigorous Komatsu standards for temperature control and preventive maintenance:
• Machine & Heavy-Duty Coolant Application Compatibility: Engineered for a broad range of Komatsu heavy-duty equipment, our products ensure exact thermal thresholds, chemical formulations, and volumetric parameters for a 100% perfect match, rapid thermal regulation, and factory-grade performance.
• Complete Heavy-Duty Coolant Range: 1. OEM Long-Life Coolants: Conforming to strict Komatsu engineering standards to provide outstanding corrosion and thermal protection for aluminum and cast-iron engine components; 2. Pre-Diluted Heavy-Duty Coolants: Precisely mixed using deionized water for immediate application, completely eliminating mineral scaling caused by high local water hardness; 3. Concentrated Coolants & SCAs: Designed to satisfy flexible dilution ratio requirements and supplemental additive needs across diverse overseas operating regions.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Komatsu coolants alongside rigorous high-performance aftermarket alternatives, delivering exceptional operational reliability and extended service lifespan at a cost-effective procurement point for global clients.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global coolant procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international equipment owners and repair facilities.
• Massive Inventory and Cross-Reference: We maintain large-volume stock of hundreds of metric tons of high-performance heavy-duty coolants matching Komatsu mainstream models. Backed by barcode-enabled intelligent warehousing and Komatsu cross-reference databases, we guarantee precise matching and immediate dispatch upon order confirmation to fulfill routine maintenance and rapid replenishment needs for overseas fleet workshops and minimize equipment downtime caused by urgent coolant replenishment needs following major overhauls or scheduled servicing.
• Liquid Sealing and Maritime Compliance: We implement specialized industrial packaging standards for liquid coolant products featuring dual-insurance anti-theft and leak-proof sealing caps alongside high-strength crush-resistant engineering plastic or iron drums. Shipments strictly adhere to international maritime chemical compliance declarations and liquid anti-tilt secured packaging to completely eliminate leakage, contamination of other cargo, or drum bursting during transit.
• Palletized and Heavy-Duty Crated Protection: Bulk drum coolants are stacked on standardized European or American pallets, secured with high-strength stretch wrap in a criss-cross pattern, and reinforced with heavy-duty wooden corner guards or container bracing. This ensures absolute protection against toppling, deformation, or leakage during transcontinental ocean logistics under salt spray, high temperatures, and long-distance transport jolts.
• Consolidated Sourcing for Engine Cooling Overhaul Kits: We support overseas clients by consolidating coolants alongside matching heavy-duty water pumps, thermostats, and water filter elements into precise bundled full-set cooling system overhaul kits, achieving a one-stop purchasing model that pairs thermal management supplies while significantly reducing comprehensive logistics costs for overseas workshops.

Engineering Solutions & Technical Support
Our technical framework focuses on resolving field-level operational challenges to eliminate equipment downtime, moving beyond simple parts distribution to deliver comprehensive engineering and service capabilities for asset health monitoring reliability.
• Application-Specific Cooling & Antifreeze Solutions: We address extreme jobsite challenges—such as hyper-arid deserts and high-load quarries—where using tap water or low-grade antifreeze causes severe vibration cavitation pitting on engine cylinder liner outer walls, eventually letting coolant leak into oil pans and trigger bearing seizure failures. We also provide professional upgrades using heavy-duty professional coolants featuring superior anti-cavitation, high boiling points, and organic acid technology.
• Troubleshooting and Maintenance Guidelines: We provide professional diagnostic guidance for issues like unexplained temperature alarms, overflowing expansion tanks, or radiator clogging. This focuses on two critical protocols: 1. Flushing, Anti-Mixing & Air Bleeding: Technicians must thoroughly flush old fluids, strictly prohibit mixing coolants with different chemical formulations (like inorganic and organic acid types) to prevent precipitation, and ensure complete air purging after filling to avoid vapor locks causing localized overheating; 2. pH, Concentration & Thermal Monitoring: Equipment directors must monitor freezing points and alkalinity using testing kits, executing immediate full-fluid changes upon detecting acidity or depleted rust inhibitors to protect expensive Komatsu engine blocks.
• Expert Technical Support & Safety Guidelines: We provide comprehensive documentation, including cooling system total capacity comparison charts, replacement and flushing standard procedures, temperature anomaly troubleshooting guides, and thermal management fault reference documents, assisting overseas technical personnel in executing standardized maintenance.
