Replacement RT28990007 Power Steering Suction Hose Reservoir to Pump 4-Cyl 2.4L

The Replacement RT28990007 is a direct-fit power steering suction hose designed to restore proper hydraulic fluid flow between the power steering fluid reservoir and the pump on compatible Toyota 4-cylinder 2.4L vehicles. This reservoir-to-pump hose is a critical component in the hydraulic power steering system, drawing fluid from the reservoir under low pressure to feed the pump.

Over time, these rubber hoses degrade due to heat, age, and exposure to power steering fluid, leading to cracking, softness, or leaks at the connection points. Replacing a worn or leaking suction hose promptly prevents pump cavitation and protects the power steering pump from premature failure.
