The 245-9207 Radiator Core Assembly is a premium aluminum replacement core for Caterpillar excavators, including models 324D, 325D, 329D, and variants (FM, FM LL, L, LN, MH) powered by the C7 engine. Designed to meet or exceed OEM CAT specifications, this core ensures efficient cooling performance under heavy use, high temperatures, and challenging working conditions.
Features
Durable Aluminum Construction – Full-aluminum core and end-tanks resistant to corrosion, vibration, thermal cycles; designed for long service life.
Lightweight & Fuel-Efficient – Compared to heavier copper/steel cores, reduced weight helps lower operational costs and reduces stress on mounting.
Strict Quality Control – Each unit is pressure tested, leak-checked, and thermally evaluated before leaving the factory. Packaging is reinforced for safe transport.

How We Produce
High-conductivity aluminum alloy for core and end-tanks; tested for strength, conductivity, and resistance to fatigue.vacuum brazing or high-integrity brazing techniques to bond fins, tubes, and tanks, ensuring leak-tight joints and consistent performance.
All fittings, mounting brackets, flange interfaces and bolt holes machined to exact OEM tolerances for perfect fit.
Surface Treatment & Protection – Cleaned and treated surface; optional anodizing or anti-corrosion coating as needed to resist oxidation and environmental damage.
Comprehensive Testing & Packaging – Includes hydrostatic / pneumatic pressure testing; thermal performance verification; vibration and impact resistance checks. Final packaging ensures protection during shipping.
