Cooling/Radiator(Cooling)

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of water radiator assemblies, aftercoolers, and cooling modules to support diverse off-highway haulers, crawler bulldozers, wheel loaders, and heavy excavators:
• Machine & Powertrain System Compatibility: Engineered for a broad range of Caterpillar heavy equipment—including off-highway mining trucks (e.g., CAT 773, 777, 785), dozers (D8, D9, D10), wheel loaders (966, 980), and large excavators—our parts ensure exact dimensional and functional alignment with original factory radiator assemblies, core elements, water tanks, and mounting brackets to guarantee a perfect match.
• Complete Radiators & Thermal Components: 1. Water Radiator Assemblies & Cores: High-efficiency tube-and-fin and lanced-fin heavy cooling cores designed with thermal expansion accommodation and vibration-crack resistance; 2. Aftercoolers & Integrated Modules: Charge air coolers (CAC) and integrated hydraulic oil radiator modules combined with primary water radiators; 3. Radiator-Associated Hardware: High-temperature cooling hoses, high-torque T-bolt clamps, rubber isolators, and drain valves.
• OEM & Heavy-Duty Aftermarket: We offer certified original equipment manufacturer Caterpillar radiators alongside rigorously tested heavy-duty aftermarket options manufactured from thickened copper alloys or reinforced aluminum via high-strength welding and 100% 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 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, bulldozer, and excavator radiators. 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 unplanned machine stoppages.
• Heavy-Duty Anti-Shock Crating and Packaging: We implement specialized industrial packaging standards for large-volume precision plate-fin and tube-and-fin radiator 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 distortion or salt-fog corrosion.
• Consolidated Sourcing: We support overseas clients by consolidating heavy radiator assemblies into precise bundled shipments alongside major overhaul components, such as engine overhaul kits, water pumps, or fan motors, 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-vibration quarries and open-pit mines, where radiator fins are frequently punctured by flying debris or clogged by compacted dust causing sudden water temperature spikes, and high alternating loads induce cracking at water tank welded joints. We also provide professional engineering upgrades, including anti-clogging wide-pitch fin designs, thickened vibration-resistant reinforced water tanks, and high-strength protective guard screens.
• Radiator Troubleshooting and Maintenance Guidelines: We address common user concerns regarding engine overheating and coolant leaks by providing professional diagnostic and replacement guidance. This includes comprehensive high-temperature diagnostic instructions helping technicians differentiate whether cooling inefficiency stems from internal scale blockages, external fin dust accumulation, thermostat failure, or water pump impeller wear, alongside emphasis on using specification-compliant extended life organic acid coolants and regular reverse high-pressure flushing to maximize radiator lifespan.
• Expert Technical Support and Safety Guidelines: We provide technical documentation covering Caterpillar engine radiator mounting pad rubber isolator replacement intervals, flexible hose anti-torsion alignment specifications, and system bleeding procedures, preventing secondary cracking caused by unreleased installation stress.
