Mercury Mariner Power Steering Cooler

The Mercury Mariner Power Steering Cooler keeps the steering fluid cool for light wheel effort and longer part life. The Power Steering Cooler is mounted on the radiator support and is located behind the grille where a steady flow of air cools the finned tubes that carry the hydraulic fluid. Every Mercury Mariner built serves this part. The hoses connect the pump to both the cooler and the reservoir. Oil from the pump passes through the Power Steering Cooler where it sheds heat to the air passing through. Once cooled, it returns as a denser liquid. All Mariner versions use the same tube-and-fin Power Steering Cooler design rather than a plate style, allowing drivers of any Mercury year to experience uniform thermal protection. Lightweight aluminum tubes with external fins dissipate heat quickly as speed increases or when the engine fan operates at idle. This design enhances the surface area of the aluminum. Cooler fluid means seals last, steering stays smooth, and foaming under tight parking moves is less likely. The load is typically handled by a routine highway breeze. However, city stop-and-go, common to many Mercury Mariner trips, is what the Power Steering Cooler is sized for. It quietly protects the hydraulic circuit from premature wear.
