Replacement REPC311104 Power Steering Oil Cooler OEM - 15009093

The Replacement REPC311104 Power Steering Oil Cooler is a direct OEM-replacement unit designed to restore proper power steering fluid temperature regulation. This external air-to-liquid cooler mounts in the front of the vehicle and uses airflow through the grille to dissipate heat from the power steering fluid, helping protect the steering rack, pump, and associated components from heat-related wear and premature failure.

The factory steel power steering cooler on these GMT360-platform vehicles is a well-known failure point — over time, the steel construction is prone to corrosion, leading to cracked tubes, clogged fins, and fluid leaks. This replacement unit features an aluminum core and aluminum tank construction for improved corrosion resistance and long-term durability.
