Complete Tractor 3506-6300 Radiator is an aftermarket replacement radiator for Caterpillar tractors that originally came with OEM radiator part number 304-7851. Our radiator quickly cools fluid to keep your tractor running smoothly during planting, growing and harvest seasons.

OEM Quality for Reliable Performance
Quality construction keeps your tractor running for years of dependable service. Radiator is sourced from factories that partner with Complete Tractor in the design and manufacture of tractor components that meet OEM specifications. Seams are securely welded for sealed, leak-free operation. Pressure-check testing ensures dependability upon delivery.

Benefits of an Aluminum Core Radiator
This radiator is equipped with an aluminum core, combining the best of lighter weight and optimal cooling efficiency. Because aluminum is stronger and harder than copper, aluminum allows building radiators with larger tube diameters, while still achieving a lighter-weight radiator overall. Larger tube diameter allows for an increased capacity to carry coolant through the core, which means more coolant undergoes the cooling process of heat exchange at any one time. Heat transfer also operates more uniformly because the core is all aluminum without any soldered joints. Because the tubes are generally larger, aluminum core radiators are often designed with fewer tubes, which allows for improved airflow through the core. Aluminum offers exceptional corrosion resistance for a long life.

Designed to Get You Back in the Field Quickly
Sturdy packaging ensures your radiator arrives protected from damage while in transit. Ready-to-ship inventory gets you back in the field without delay. This radiator is typically priced 30% less than OEM components without compromising quality because of our factory direct relationship.
