Features & Benefits

  • Engine Oil Cooler Core: 398-4347 CORE AS-OCLR is designed for the engine oil cooling system of Caterpillar track-type tractors.
  • Efficient Heat Transfer: The cooler core transfers heat from engine oil to the cooling medium, helping maintain suitable oil operating temperatures.
  • Engine Protection: Proper oil temperature management helps maintain lubrication performance and protects internal engine components under demanding operating conditions.
  • Heavy-Duty Construction: Designed for Caterpillar equipment exposed to continuous workloads, vibration, dust, and elevated operating temperatures.
  • Reliable Cooling Performance: A properly functioning oil cooler helps reduce excessive oil temperature and supports consistent engine performance.
  • Maintenance Replacement: Suitable for oil cooler repair, preventive maintenance, and cooling-system overhaul.
  • CAT Application: Designed for D6-series track-type tractors, including D6R, D6R XL, and D6N applications.
  • Support for Long Working Cycles: Reliable oil cooling is especially important for machines operating continuously under heavy loads in earthmoving and construction environments.
