TOYOTA 44360-60220 Power Steering Oil Reservoir Assembly

This genuine OEM TOYOTA (OEM: 44360-60220) power steering fluid reservoir (RESERVOIR ASSY, OIL) is an essential component of the hydraulic power steering system. Genuine OEM parts guarantee a perfect fit, maximum reliability, and long service life, avoiding dimensional inaccuracies or premature failures caused by material fatigue often associated with aftermarket products.

Function and Importance in the Vehicle

The primary function of the power steering fluid reservoir is to store the hydraulic fluid circulating within the steering system and to compensate for volume fluctuations caused by thermal expansion. In addition, it plays a vital role in separating air bubbles from the fluid and keeping the system clean. The internal filter located inside the reservoir filters the circulating fluid, preventing metal wear particles and other contaminants from reaching the precision power steering pump or steering gear.

Common Symptoms of Failure or Wear

• Leaks and cracks: Due to continuous thermal stress and environmental influences, the plastic housing can become brittle over time and crack, leading to power steering fluid loss.
• Clogged internal filter: If the integrated filter becomes clogged, the pump does not receive sufficient fluid, causing cavitation, a loud whining or humming noise, and premature pump failure.
• Foaming power steering fluid: If air enters the system due to leaks in the reservoir or its connections, the power steering fluid can foam, degrading steering efficiency and resulting in stiff or heavy steering.
