Oil Cooler Kit for Ford F250 F350 Super Duty (2011-2019) 6.7L Diesel Engine

High-Efficiency Engine Oil Cooler Kit for 2011-2019 Ford F-250, F-350 (6.7L Scorpion / P473)

What It Does: This heavy-duty oil cooler regulates engine oil temperature by transferring heat to the engine coolant, maintaining optimal viscosity and preventing thermal breakdown during high-load cycles.

The Stock Ford 6.7L Power Stroke Thermal Restriction

In the 6.7L Scorpion engine, the factory oil cooler is a notorious bottleneck for high-mileage trucks. Over time, the narrow internal passages are susceptible to clogging from silicate dropout or cooling system debris. When flow is restricted, oil temperatures escalate rapidly, often exceeding the cooling capacity of the system. This leads to a dangerous 'Delta T' spread between oil and coolant temperatures, which can trigger limp mode, degrade oil quality, and eventually cause premature wear on main bearings and turbocharger components. Furthermore, the OEM seals are known to harden over time, leading to external leaks or internal cross-contamination.

The Engineering Solution

This replacement kit is engineered to restore and exceed factory cooling efficiency. It features a stack-and-plate design forged from high-grade aluminum with reinforced vacuum-brazed joints to handle the extreme pressure spikes found in diesel lubrication systems. The internal fluid paths are precision-machined to ensure laminar flow, maximizing heat dissipation while resisting the accumulation of sludge and contaminants. By utilizing upgraded high-temp fluoropolymer gaskets, this unit eliminates the risk of oil-to-coolant mixing. The result is a more stable thermal profile, ensuring your 6.7L maintains consistent oil pressure and lubrication even under maximum towing GVWR.
