What is this part and why does it matter?

The power steering pump generates hydraulic pressure to reduce steering effort, driven by the engine’s accessory belt.

Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Heavy steering effort, especially at low speed or when parking
  • Whining or groaning noise when turning the wheel
  • Fluid leak near the pump

Installation information

Requires draining the power steering fluid before removal — always bleed the system thoroughly after refilling to remove trapped air.

Frequently asked questions

This is a classic symptom of low fluid level, air trapped in the system, or a worn pump — a whining noise specifically when turning (rather than constant) often points to the pump itself struggling under load.

  • I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

  • No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

  • Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
