Power steering coolers are especially important on SUVs like the Buick Rainier, where heavy vehicle weight and demanding driving conditions can generate significant heat in the steering system. This cooler installs in the power steering return line and uses airflow to dissipate heat from the fluid before it returns to the reservoir. Regular inspection and timely replacement of a failing power steering cooler can prevent costly damage to other steering system components and maintain smooth, responsive steering feel.
