Other General Parts/Oil Cooler(Cooling)

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of specialized oil coolers within our Other General Parts catalog to support diverse heavy-duty equipment. Our product lineup covers a broad range of machine series and thermal management configurations, ensuring that every component meets rigorous Komatsu standards for temperature control and preventive maintenance:
• Machine & Heavy-Duty Thermal Management Compatibility: Engineered for a broad range of Komatsu heavy-duty equipment, our products ensure exact heat transfer coefficients, working pressure tolerances, and connection interface definitions for a 100% perfect match, rapid replacement, and factory-grade performance.
• Complete Heavy-Duty Oil Cooler Range: 1. Hydraulic & Transmission Oil Coolers: Designed for high flow rates and high-pressure return pulse impacts, featuring exceptional cooling coefficients for primary system assemblies; 2. Engine Oil Cooler Cores & Brazed Plate Assemblies: Formulated to maintain consistent engine internal lubrication oil temperatures and prevent thermal viscosity degradation; 3. Combined Cooling Modules & Integration Parts: Satisfying dense spatial arrangements and efficient airflow guidance for high-horsepower mine equipment.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Komatsu oil cooler assemblies alongside rigorous high-performance aftermarket alternatives featuring reinforced anti-corrosion alloy materials, 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 thermal management component 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 engine and hydraulic oil coolers matching Komatsu mainstream excavators, loaders, and mining trucks. 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 sudden radiator core punctures or oil leaks halting complete machine operations.
• Shock-Absorbing Packaging and Port Protection: We implement specialized industrial packaging standards for oil cooler assemblies utilizing high-strength threaded protective plugs on all inlet and outlet ports, thick pearl cotton and anti-vibration foam boards surrounding the main body, and custom suspended wooden cradles at the bottom to ensure zero metal corrosion or fin crushing deformation during transcontinental ocean freight under salt spray and high humidity environments.
• Heavy-Duty Crated Protection: Bulk heavy-duty oil cooler shipments are packed in high-strength export fumigated wooden crates with internal anti-vibration cork positioning blocks to guarantee absolute safety during long-distance transcontinental transport under extreme cargo handling jolts without knocks or leakage.
• Consolidated Sourcing for Oil Cooler Overhaul Kits: We support overseas clients by consolidating large oil coolers alongside matching full sets of high-temperature-resistant fluororubber seal rings, professional system cleaning agents, and compatible lubricating oils into precise bundled full-set oil cooler maintenance kits, achieving a one-stop purchasing model that pairs cooling system service 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 Thermal Enhancement Solutions: We address extreme jobsite challenges—such as high-heat desert open-pit mines and continuous full-load heavy loading operations—where original standard coolers develop fatigue cracks at brazed joints under long-term high-temperature and high-pressure pulses, causing hydraulic oil to leak into cooling water tanks. We also provide professional engineering upgrades utilizing enhanced vacuum brazing processes, thickened anti-pulse oil channel walls, and wider anti-clogging fin spacings.
• Troubleshooting and Maintenance Guidelines: We provide professional diagnostic guidance for issues like frequent temperature alarms and sluggish machine performance after a few hours of operation. This focuses on two critical protocols: 1. Reverse Flushing & Chemical Descaling: Technicians must use compressed air or warm water for external dust reverse purging and mandate professional degreasing detergent circulation for internal sludge, strictly prohibiting blind hard-tool rodding; 2. Pressure Testing & Bypass Valve Inspection: Service technicians must inspect Komatsu radiator bypass valves for sticking during replacement to prevent cold-start high-pressure surges from bursting new units.
• Expert Technical Support & Safety Guidelines: We provide comprehensive documentation, including cooler disassembly diagrams, pipe connection torque specifications, high-temperature maintenance guides, and oil-water mixing troubleshooting visual documentation, assisting overseas technical personnel in executing standardized construction.
