Hydraulic Oil Radiator - CATERPILLAR
High-quality hydraulic oil cooler with part number 521-6481. This is a thermal system component, designed for heavy construction machinery from the Caterpillar brand. This cooler is used in a wide range of track-type tractors (dozers) (from D5 to D8 series) and in proven G-series motor graders. Its main task is to maintain the optimal temperature of the hydraulic fluid, which prevents pump overheating and pressure loss during intensive earthworks.
Product Features:
- Efficient heat exchange: Optimized core design ensures rapid cooling of oil returning from the working system, protecting seals and hydraulic components against thermal degradation.
- Robust construction: Cooler resistant to vibrations, shocks, and high pressure, adapted to difficult working conditions on construction sites and in mines.
- Wide compatibility: Fits many generations of CAT machines, providing a reliable replacement solution for equipment working under heavy load.

Technical Tip: In machines working in high dust environments (dozers, graders), the cooler fins are particularly prone to clogging. Regular cleaning of the external surface of the cooler with compressed air is crucial for maintaining its efficiency. When installing a new cooler, check the condition of the flexible oil supply hoses and replace the hydraulic filter to remove contaminants from the system.
