The steering system used in Volvo V70s is known as power-assisted rack-and-pinion steering. Rotating the steering wheel spins a small pinion gear, thus sliding a toothed rack left or right. The ends of the rack attach to tie-rods, which steer the front wheels. A hydraulic pump, powered by the engine accessory belt, forces steering fluid into hoses leading to pistons in the steering rack. A hydraulic valve in the steering rack varies the hydraulic fluid pressure in the two cylinders, dependent on how fast or forcefully the pinion gear is rotated. This multiplies the driver's force in steering the wheels.

When a power steering pump begins to fail, it will emit a groan when steering from side to side or you will notice increased steering effort. Of course, the pump could leak also, but a noisy and weak pump is most common. The power steering reservoir is constructed of plastic and often cracks or is damaged during repair procedure.

In this article, I'll go over the steps involved with replacing the power steering reservoir, replacing the hoses to the reservoir and bleeding the power steering pump.

Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Do not work on your vehicle if you feel the task is beyond your ability.

Vehicle models change and evolve, as they grow older, so the vehicle shown in our illustrations may vary slightly from yours. If something seems different, let us know and share your info to help other users. Do you have questions or want to add to the article? Leave a comment below.

Place an oil drain pan under the right side of the engine.

The power steering reservoir is mounted on the right side of the engine compartment, on the strut tower (yellow arrow).
Figure 1

The power steering reservoir is mounted on the right side of the engine compartment, on the strut tower (yellow arrow). There are two power steering lines that attach to the reservoir. These hoses can harden and leak over time. One line runs to the steering rack (red arrow). The other line feeds the power steering pump (green arrow).

Use a suction pump to suck the power steering fluid out of the reservoir.

Now it's time to remove the hoses from the power steering reservoir.
Figure 3

Now it's time to remove the hoses from the power steering reservoir. Working at the power steering pump, loosen the hose clamp (green arrow). Then pull the hose straight off the reservoir.

To replace the previously disconnected line, follow it to the firewall and pull the line out of the mount (green arrow).
Figure 4

To replace the previously disconnected line, follow it to the firewall and pull the line out of the mount (green arrow). Lift and support the front of your vehicle on jack stands.

Working at the subframe, remove the T25 Torx fastener (green arrow).
Figure 5

Working at the subframe, remove the T25 Torx fastener (green arrow). Then remove the 10mm fastener (red arrow). Next, remove the 19mm line nut at the power steering rack (yellow arrows). Then remove the line from the vehicle and install the new one in the reverse order.

Working at the power steering pump, use a flathead screwdriver and loosen the hose clamp (green arrow).
Figure 6

Working at the power steering pump, use a flathead screwdriver and loosen the hose clamp (green arrow). Pull the hose out of the mount (red arrow).

Once you get the hose clamps loose, pull the hose straight off the pump.
Figure 7

Once you get the hose clamps loose, pull the hose straight off the pump. Be ready for any excess fluid to leak out with a rag (green arrow).

Now comes the tricky part.
Figure 8

Now comes the tricky part. The power steering reservoir is mounted to the coolant reservoir with a plastic clip and two guides. The clip can be tough to detach (green arrow). The power steering reservoir clip has the retaining tab. I like to gently lever the clip from below, toward the coolant reservoir to unlock it. I then lift it upward. As you lift up, use a flathead screwdriver to gently lever the power steering reservoir out of the coolant reservoir, upward.

Lift the reservoir up enough to access the hose beneath it.
Figure 9

Lift the reservoir up enough to access the hose beneath it. Use a flathead screwdriver to lever the clamp open (green arrow). Remove the hose from the reservoir. You can now remove the reservoir from the engine or replace the hose with a new one. Use new hose clamps and be sure to bleed the power steering pump when done. Before starting the engine, fill the power steering reservoir with clean fluid to the MAX level on the dipstick. Start the engine and turn the steering wheel fully left and right three times. Turn the engine off, check the fluid level and add fluid until it reaches MAX on the dipstick. When full, the fluid should be clear and foam free. Foam or bubbles is a sign of air in the system.
