Who is correct regarding the purpose of a power steering cooler?

The purpose of a power steering cooler is to prevent the fluid from overheating, which is essential for maintaining the efficiency and longevity of the power steering system. When the fluid gets too hot, it can degrade, leading to the breakdown of the fluid’s ability to properly lubricate and assist in steering. This can result in increased wear on the power steering components and may ultimately lead to failure.

Technician A correctly understands that a power steering cooler is used to control the temperature of the fluid within the power steering system, ensuring optimal performance. Proper cooling helps avoid conditions that can cause steering effort to increase and can help maintain consistent operation regardless of driving conditions.

While it is important to recognize the contributions of all technicians to the discussion, Technician A's description captures the primary function of the power steering cooler effectively, emphasizing the need for temperature regulation in steering fluid.
