Paccar Oil Coolers in Diesel Engines

The oil cooler is part of the engine’s lubrication and thermal management system. As oil circulates through the engine, it passes through the cooler where excess heat is removed, helping maintain proper viscosity and lubrication performance.

Paccar oil coolers help support:

• Stable engine oil temperature
• Protection of crankshaft and camshaft bearings
• Improved lubrication efficiency
• Reduced oil degradation under heavy loads
• Long-term engine durability

Proper oil temperature control is essential for maintaining lubrication quality and protecting internal engine components.

Common Paccar Engine Applications

Paccar oil coolers are widely used across modern heavy-duty diesel engines installed in Kenworth and Peterbilt truck platforms.

• Paccar MX-11 diesel engines
• Paccar MX-13 diesel engines
• Kenworth T680 and T880 trucks
• Peterbilt 579 and 567 truck platforms

Different engine generations may require specific oil cooler designs depending on cooling system layout and engine configuration.

Common Oil Cooler Failure Symptoms

• Engine oil overheating
• Oil contamination with coolant
• External oil leaks
• Reduced lubrication efficiency
• Engine overheating warnings

Oil cooler problems may occur due to internal corrosion, clogging, pressure damage, or seal deterioration over time.

Verify Fitment Before You Buy

Oil coolers vary depending on engine model and cooling system configuration. To confirm compatibility before ordering, provide:

• Engine serial number
• Truck year / make / model
• Current oil cooler part number
• Photos of the oil cooler if available

This information helps ensure the correct Paccar oil cooler is selected for your application.
