Cummins Oil Coolers
Cummins oil coolers help regulate engine oil temperature to maintain proper lubrication and protect critical engine components. By removing excess heat from circulating oil, the oil cooler prevents oil breakdown and supports stable engine performance. At Advanced Truck Parts, we supply Cummins oil coolers designed for reliable operation in heavy-duty diesel engines.

Cummins Oil Coolers in Diesel Engines
The oil cooler is part of the engine’s lubrication and thermal management system. It lowers the temperature of engine oil as it circulates through the engine, helping maintain proper viscosity and lubrication characteristics.
Cummins oil coolers help support:
- Stable engine oil temperature
- Improved lubrication performance
- Protection of crankshaft and camshaft bearings
- Reduced oil degradation under heavy loads
- Long-term engine durability
Maintaining proper oil temperature is essential for protecting internal engine components and ensuring consistent performance.
Common Cummins Engine Applications
Cummins oil coolers are widely used across both heavy-duty and medium-duty diesel engines installed in commercial truck platforms.
- Cummins ISX CM870, CM871, CM2250, and CM2350 engines
- Cummins X15 Performance and Efficiency Series
- Cummins ISB 6.7L diesel engines
- Cummins ISC and ISL diesel engines
- Kenworth, Peterbilt, Freightliner, and International trucks
Different engine models and cooling system configurations may require specific oil cooler designs, so confirming the correct part number is important before replacement.
Common Oil Cooler Failure Symptoms
- Engine oil overheating
- Oil contamination with coolant
- External oil leaks
- Reduced lubrication efficiency
- Engine overheating or warning indicators
Oil cooler failures may occur due to internal corrosion, clogging, pressure damage, or gasket deterioration over time.
Verify Fitment Before You Buy

- Engine serial number (preferred)
- CPL number
- Truck year / make / model
- Current oil cooler part number
- Photos of the oil cooler if available
This information helps ensure the correct Cummins oil cooler is selected for your application.
