Oil Cooler Kit for Ford E-Series F-Super Duty & Excursion (2003-2010) 6.0L Diesel Engine

High-Efficiency Oil Cooler Kit for 2003-2010 Ford F-250, F-350, F-450, F-550, E-350, E-450, E-550, Excursion (6.0L Power Stroke)

What It Does: Replaces the factory heat exchanger to maintain critical thermal regulation between engine oil and coolant, preventing catastrophic high-temperature deltas that lead to system-wide failure.

The Stock Ford 6.0L Power Stroke Thermal Weakness

The factory oil cooler in the 6.0L Power Stroke is a notorious failure point due to its restrictive internal architecture. The OEM unit features exceptionally narrow cooling fins that are prone to clogging from suspended particulates, sand casting debris, and silicate fallout from the engine coolant. Once these passages become obstructed, the Engine Oil Temperature (EOT) rises significantly above the Engine Coolant Temperature (ECT). This excessive heat soak compromises oil viscosity, starves the High-Pressure Oil Pump (HPOP), and is the primary catalyst for EGR cooler rupture and head gasket failure in the VT365 engine platform.

The Engineering Solution

This heavy-duty Oil Cooler Kit is engineered to restore and improve heat transfer efficiency. Constructed from high-grade cast iron and aluminum alloys, the internal stack is designed to maximize surface area contact without the restrictive flow dynamics found in early-generation stock units. By maintaining a consistent Oil Temperature Delta (OTD), this kit ensures that lubrication remains stable even under extreme towing and high-load conditions. The package includes all necessary gaskets and precision-machined hardware to ensure a leak-free seal and seamless integration with the factory engine housing, effectively prolonging the service life of the fuel injectors and valvetrain.

The Ford Heavy-Duty Standard

For the Super Duty and E-Series platforms, maintaining thermal equilibrium is the difference between job site reliability and expensive downtime. This oil cooler is built for the rigors of heavy towing and high-idle commercial use, providing the mechanical durability required for the 6.0L diesel's demanding oil-fired injection system.
