🔧 Why Invest in OEM Brand Hydraulic Pumps

A failing power steering pump not only makes the driver's job harder, but it can also shed tiny metal shavings that can damage the steering box, resulting in a much more expensive repair. By installing a TRW or LUK pump, you ensure a clean and powerful system.

Benefits of using premium brand pumps:

• Elimination of excessive effort when turning the steering wheel under full load
• Silent operation without moaning or annoying hydraulic noises
• Steering box protection against metallic contamination
• Constant pressure that guarantees immediate system response
• High-strength seals that prevent costly fluid leaks

Signs that you need to replace the hydraulic pump:

• A groan or whine when turning the steering wheel, especially when cold.
• Excessive effort required to turn the steering wheel
• Hydraulic fluid leaks under the engine
• Fluid level in the reservoir is constantly dropping
• Direction that feels "heavy" or inconsistent

Required Components When Replacing the Hydraulic Pump:

• New power steering filter: Protects the new pump from contamination of the old system.
• New hydraulic fluid: Use ATF or hydraulic oil according to OEM specifications to validate the warranty
• Pressure hoses: Inspect and replace if they show cracks or bulges.
• Complete system purge: Remove trapped air for quiet operation

Installation Recommendations:

• Always change the power steering filter when installing a new pump
• Use new fluid of the type specified by the vehicle manufacturer
• Purge the system completely to remove trapped air.
• Check the pump belt tension - not too loose and not too tight
• Inspect the pump pulley for wear or damage
• Clean all connections before assembly
• Tighten all connections according to torque specifications

Installation Procedure:

• Disconnect the batteries before starting
• Drain the hydraulic fluid from the reservoir
• Remove the pump band
• Disconnect the pressure and return hoses
• Remove the mounting bolts from the old pump
• Clean the mounting area on the engine
• Install the new pump with new gaskets
• Connect the hoses with new washers.
• Install and adjust the band to the correct tension.
• Fill the reservoir with new fluid.
• Bleed the system by turning the steering wheel from lock to lock several times
• Check the fluid level and adjust if necessary
• Inspect for leaks after starting the engine

System Purge Procedure:

• Fill the reservoir with new fluid to the maximum level
• With the engine off, turn the steering wheel from lock to lock 10-15 times
• Check and top up the fluid level as needed
• Start the engine and let it idle.
• Turn the steering wheel from lock to lock several more times
• Check that there are no bubbles in the tank
• Adjust the final fluid level

Preventive Maintenance:

• Inspect the hydraulic fluid level weekly
• Check hoses and connections regularly for leaks.
• Inspect the pump belt tension monthly
• Change the hydraulic fluid according to the manufacturer's recommendations
• Replace the power steering filter at every fluid change
• Listen for abnormal noises when turning the steering wheel

Pro Tips:

• Use only the specified fluid type - ATF or hydraulic oil as per OEM
• Never mix different types of hydraulic fluid
• Check the pulley alignment before installing the belt
• Document the pump part number for future reference.
• Inspect the steering box for leaks at the same time
• Consider replacing the hoses if they are more than 5 years old.
