The Ford 6.0L Power Stroke diesel has earned quite a reputation. This reputation is hampered by some pattern failures, including:
EGR Cooler Rupture/Leaking
Engine Oil Temperature overheating
Blown Head Gasket
Fuel Injector Failure
High-Pressure Oil Pump Failure
All of these problems have a common thread: The OEM Engine Oil Cooler
The problem with the engine oil cooler arises when the coolant flows through the tight passageways of the engine oil cooler (see picture). These pathways are so small that they catch and stop any large particles suspended in the coolant, blocking the channel. While the mileage varies, it typically takes about 50,000 miles before the coolant can no longer flow through the cooler on its way to the EGR cooler, leaving less and less coolant flow for your engine oil cooler AND for your EGR cooler.
A plugged up engine oil cooler can lead to a ruptured EGR cooler, overheated engine oil, overheated fuel injectors, loss of coolant, ruptured engine oil cooler and blown head gaskets.
Replacing the Ford engine oil cooler with another Ford engine oil cooler is simply putting off the problem for another 50,000 miles. The best solution? Upgrade your engine oil cooler to the BulletProof Engine Oil Cooler. The advantages include:
More effective engine oil cooling
Improved cooling of the EGR cooler, leading to increased EGR cooler longevity
Reduced engine oil temperatures
Improved engine oil filtering: add on an oil-bypass filtration kit, too
Eliminates engine oil in your coolant by way of a ruptured engine oil cooler
Cooler, better-filtered oil for your injectors and high pressure oil pump
