What Does the Engine Oil Cooler Do in a 6.0L Diesel?
The engine oil cooler is a heat exchanger that uses engine coolant to regulate oil temperature in the 6.0L Power Stroke diesel. This component is critical because diesel engines generate extreme heat, and maintaining optimal oil temperature (typically 180-220°F) protects internal engine components from thermal breakdown and premature wear.
In the 6.0L diesel design, the oil cooler sits in the valley of the engine block and uses coolant passages to transfer heat away from the engine oil. When functioning properly, it keeps oil viscosity stable and prevents sludge formation. The APDTY 015339 kit restores this cooling function with all necessary sealing components to prevent the cross-contamination issues that plague worn factory coolers.
What Are the Symptoms of a Failed 6.0L Oil Cooler?
Oil cooler failure in the 6.0L diesel typically manifests through several recognizable symptoms:
- Coolant in the oil: Milky or tan-colored oil on the dipstick or under the oil cap indicates coolant leaking into the oil passages
- Oil in the coolant: Oil film or droplets floating in the coolant reservoir or radiator
- Engine overheating: Restricted coolant flow through the cooler can cause elevated engine temperatures
- White exhaust smoke: Coolant burning in the combustion chamber if contamination is severe
- Loss of coolant: Unexplained coolant loss without visible external leaks
- Poor oil pressure: Diluted oil from coolant contamination reduces lubrication effectiveness
The 6.0L oil cooler is a known weak point, with internal passages prone to cracking and seal deterioration over time. Catching failure early prevents catastrophic engine damage from running contaminated oil.
What Vehicles Does APDTY 015339 Fit?
According to APDTY's product specifications, the 015339 oil cooler kit is compatible with 2003-2010 Ford and International trucks equipped with the 6.0L diesel engine.

How Do You Install an Engine Oil Cooler on a 6.0L Diesel?
Installing the APDTY 015339 oil cooler kit on a 6.0L diesel is an advanced repair that requires mechanical skill and proper tools. While complete factory service procedures should be followed, the general process includes:
- Drain fluids: Completely drain engine oil and coolant from the system
- Remove components: Access requires removing the turbocharger, exhaust components, fuel filter housing, and other obstructing parts to reach the cooler in the engine valley
- Extract failed cooler: Unbolt and carefully remove the old oil cooler assembly, noting coolant and oil passage routing
- Clean surfaces: Thoroughly clean all mating surfaces on the engine block, removing old gasket material and debris
- Install new seals: Position new gaskets and O-rings included in the kit according to factory specifications
- Install cooler: Mount the new APDTY 015339 cooler assembly and torque fasteners to specification
- Reassemble components: Reinstall all removed parts in reverse order
- Fill and bleed: Refill with fresh oil and coolant, properly bleeding air from the cooling system
- Test and inspect: Run the engine, check for leaks, and monitor oil and coolant condition
Safety note: Allow the engine to cool completely before beginning work. Hot coolant and oil can cause severe burns. This repair is best suited for experienced technicians or DIYers with significant mechanical experience. If you're uncomfortable with this level of repair, consult a qualified diesel mechanic.
Frequently asked questions
Does the APDTY 015339 kit include everything needed for installation?
Yes, the kit includes the oil cooler assembly, all necessary gaskets and O-rings, and an oil filter. You'll need fresh coolant and engine oil for refilling after installation, but all hardware specific to the cooler replacement is included.
How long does it take to replace a 6.0L diesel oil cooler?
An experienced technician typically requires 6-10 hours for complete oil cooler replacement on a 6.0L diesel, as access requires removing the turbocharger and other components. First-time DIY repairs may take considerably longer.
Will this fix coolant in my 6.0L diesel oil?
If coolant contamination is caused by a failed oil cooler (the most common cause in 6.0L diesels), the APDTY 015339 kit will resolve the issue. After installation, perform multiple oil and filter changes to flush residual coolant from the system before returning to normal service intervals.
Do I need special tools to install this oil cooler kit?
You'll need standard mechanic's tools including torque wrenches, sockets, and wrenches. Some steps may require specialty tools like a coolant system pressure tester for verification after installation. Consult a factory service manual for complete tool requirements and torque specifications.
The APDTY 015339 Engine Oil Cooler Kit provides a complete solution for one of the most common failure points in 2003-2010 Ford and International 6.0L diesel trucks.
