Removing the power steering pump Renault Duster

We remove the power steering pump for its replacement or when dismantling the engine.

With a bulb we pump the liquid out of the power steering reservoir

We remove the auxiliary drive belt (article – Checking and replacement of the auxiliary drive belt Renault Duster).

We remove the front bumper (article – Removal and installation of the bumpers Renault Duster)

We remove the radiator fan shroud and shift the radiator with the air conditioning condenser on the hoses forwards.

We place a container for collecting the liquid under the power steering pump and cover the alternator with polyethylene.

Having squeezed with pliers the clip securing the hose of the filler line, we shift the clip along the hose and remove the hose from the pump union.

We remove the pump.

We install the power steering pump in the reverse order.

We install the auxiliary drive belt.

We pour the working liquid into the power steering reservoir and remove the air from the system.

Bleeding of the power steering system

The bleeding of the power steering system is necessary to remove the air that has entered the hydraulic drive during the repair or replacement of individual components of the system.

The air that has entered the hydraulic drive causes a decrease in the efficiency of the power steering.

To bleed the hydraulic system with a cold engine not running, we open the cap of the power steering reservoir and add liquid to the reservoir up to the MIN mark.

We start the engine and at idling check the liquid level in the reservoir.

When the liquid level drops, we add it up to the MIN mark.

We turn the steering wheel several times to the left and to the right as far as it will go, watching that the liquid level in the reservoir is near the MIN mark and, if necessary, we add liquid.

We return the steered wheels to the position of straight-line movement of the vehicle and let the engine run for another two or three minutes.

Then we again turn the steering wheel to the left and to the right as far as it will go and if necessary add liquid to the reservoir up to the MIN mark.

We stop the engine and again check the liquid level in the reservoir.

After warming up and stabilising the temperature of the working liquid, its level must be at the MAX mark, and in the cold state — not drop below the MIN mark.

The normal operation of the power steering must not be accompanied by increased noise, and no air bubbles should be visible in the liquid.

The effort on the steering wheel with the engine running must be considerably less than with the engine not running.

The noise of the operation of the power steering with the front wheels turned as far as they will go is not a fault.

We close the cap of the power steering reservoir.
