Cooling/Oil Cooler(Cooling)

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of engine oil coolers, hydraulic oil radiators, and transmission oil coolers to support diverse mining truck, crawler bulldozer, wheel loader, and high-horsepower excavator requirements:
• Machine & Powertrain System Compatibility: Engineered for a broad range of Caterpillar heavy equipment—including heavy-duty engines (e.g., CAT C15, C18, 3406, 3512), off-highway haulers (777, 785), and dozers (D8, D9, D10)—our parts ensure exact dimensional and functional alignment with original factory cooler assemblies, heat-exchange cores, flange interfaces, and sealing gaskets to guarantee a perfect match.
• Complete Oil Coolers & Thermal Components: 1. Engine Oil Coolers & Cores: Plate-fin and shell-and-tube high-efficiency heat exchangers and multi-layered stacked radiator cores; 2. Hydraulic & Transmission Coolers: Independent or integrated oil coolers engineered for high-pressure systems and powershift transmissions to maintain optimal fluid temperatures during heavy workloads; 3. Thermal Management Seals & Lines: Cooler overhaul sealing kits, high-temp O-rings, water pipes, and rigid oil line assemblies.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Caterpillar oil coolers alongside rigorously tested heavy-duty aftermarket options manufactured with high-thermal-conductivity copper alloys or reinforced aluminum plate-fin structures and verified through high-pressure leak testing, delivering exceptional heat-exchange efficiency and extended fatigue life at a cost-effective price point for global clients.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global machinery thermal management component procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international buyers.
• Ready-to-Ship Inventory and Part Verification: We maintain large-volume stock of high-demand CAT mining truck, excavator, and bulldozer oil coolers. Backed by professional technical teams and heavy machinery parts databases, we guarantee precise matching and direct dispatch upon order confirmation to minimize equipment downtime caused by cooling system failures leading to engine overheating and scoring.
• Heavy-Duty Anti-Shock Crating and Packaging: We implement specialized industrial packaging standards for precision plate-fin cooler cores and large-volume cooler assemblies, utilizing internal high-density expanded polyethylene foam suspension fixing, moisture-proof vacuum sealing, custom fumigated solid wood crates or thickened honeycomb master cartons, and steel-banded locking reinforcement to ensure parts withstand transcontinental ocean or air transit without mechanical impact distortion or salt-fog corrosion.
• Consolidated Sourcing: We support overseas clients by consolidating heavy oil coolers into precise bundled shipments alongside major overhaul components, such as engine overhaul kits, water pumps, or turbochargers, maximizing container space utilization and significantly reducing international freight costs.

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.
• Application-Specific Durability Solutions: We address common field issues in extreme working environments, such as high-dust, high-ambient-temperature quarries and mines, where oil cooler internals suffer from oil carbonization blockages leading to sudden drops in cooling efficiency, and high-pressure pulses cause cooler tube bundles to crack and leak coolant into the oil. We also provide professional engineering upgrades, including anti-coking reinforced heat-exchange cores and high-strength impulse-resistant oil cooler assemblies.
• Cooler Troubleshooting and Maintenance Guidelines: We address common user concerns regarding excessive oil temperatures and oil-coolant mixing by providing professional diagnostic and replacement guidance. This includes instructions on how technicians can determine whether oil-coolant mixing stems from internal core cracking or cylinder liner water seal failures to avoid unnecessary replacements, alongside emphasis on professional lubrication system flushing prior to installing new coolers to remove residual emulsified sludge and metal debris and prevent secondary blockages.
• Expert Technical Support and Safety Guidelines: We provide technical documentation covering Caterpillar engine oil cooler mounting pad flatness inspection standards, correct seal positioning, and bolt torque specifications, preventing secondary leaks caused by improper installation.
