Universal Oil Cooler Cores

Inside an oil cooler is the core itself—a network of aluminum or copper tubes and fins engineered to maximize surface area for heat transfer. As hot oil flows through the tubes, the fins dissipate heat to the surrounding air or coolant, allowing the core to regulate oil temperature and keep engine or hydraulic systems operating safely.

A failing oil cooler can cause oil overheating, leading to reduced lubrication, increased component wear, and potential engine or hydraulic system failure. Symptoms include rising oil temperature gauges, oil leaks at the cooler housing, contaminated coolant (if oil mixes with coolant), and reduced equipment performance. Continued operation with a bad oil cooler risks catastrophic engine or transmission damage.

Radiator Supply House stocks oil cooler cores compatible with over 300 manufacturers, including Caterpillar, John Deere, Komatsu, Volvo, JCB, Doosan, Hitachi, Kobelco, Bobcat, Sullair, Atlas Copco, and Freightliner. Coverage spans construction, agricultural, industrial compressor, forestry, and commercial trucking equipment brands, with OEM-equivalent replacements engineered for direct-fit installation.

Pricing varies significantly by equipment make, model, and cooler size, ranging from approximately $1,297 to over $22,000 per unit. Smaller cores for compact equipment or compressors sit at the lower end, while large-capacity cores for heavy construction or mining machinery command higher prices. Exact pricing is listed per SKU on the product catalog.

These are OEM-equivalent aftermarket replacements, engineered to match original equipment specifications for direct-fit installation without modification. They're designed to deliver comparable performance, durability, and cooling capacity to factory parts, offering a cost-effective alternative for construction, agricultural, and industrial equipment maintenance and repair.

Yes, oil cooler cores are manufactured for specific fluid applications, including hydraulic oil, engine oil, and transmission oil. While the core construction principle is similar, internal tube configuration, pressure ratings, and fitting types differ by fluid type and equipment model, so it's important to select a core rated for your specific application.

Share your equipment's make, model, and specs with the Radiator Supply House cooling specialists, who can cross-reference this information against a stocked catalog of over 1,469 OEM-equivalent SKUs covering 300+ manufacturers to locate the exact direct-fit part for your machine.
