👉 Cab fluid, also known as power steering fluid, is a crucial component in automotive systems that facilitates the operation of power steering. It circulates through the power steering pump, which pressurizes the fluid to create the necessary force for steering the vehicle. This fluid is typically a mixture of water, glycol (to lower the freezing point and increase viscosity), and additives that enhance its performance and protect internal components. Over time, cab fluid can degrade due to exposure to heat, contaminants, and oxidation, leading to changes in viscosity and potentially causing reduced steering performance or even system failure. Regular fluid checks and replacements are essential to maintain optimal power steering function and overall vehicle safety.
