Install reservoir power steering pump

Place the vehicle in park or neutral with the emergency brake set. Raise the hood and disconnect the negative battery cable with an end wrench. Refer to your owner's manual to locate the power steering pump and the belt tensioner for the serpentine belt.

Place a socket and wrench over the large nut on the belt tensioner and twist the wrench to unload the belt pressure. Slip the belt off the power steering pump pulley. Remember the routing configuration of the serpentine belt, or refer to the diagram in your repair manual.

Place a drip pan underneath the power steering pump to catch drippings. Use a fuel line wrench to loosen the metallic nut that holds the high-pressure fluid line to the pump body. Pull the metallic line away from the pump body. Use a slot screwdriver to loosen the hose clamp on the low-pressure rubber fluid line that leads into the pump body. Pull both lines away for access to the pump. Use the correct size socket on the end of an extension to remove the three bolts that hold the pump body to the block.

Some power steering pumps have holes in their pulleys. If this is the case, rotate the pulley and stick the extension and socket through the pulley holes. Turn the bolts counterclockwise to remove them. Pull the power steering pump free from the engine compartment. Locate the two metal snap flanges on each side of the reservoir. Use a slot screwdriver to pry them apart and pull the reservoir out of the pump body. The reservoir will have a large tube nipple that slips out of the pump body.

Be sure to keep the O-ring inside the pump. Wipe off the mating surface between the pump and reservoir with a rag. Push the new reservoir into the pump body, making sure the large nipple seats inside the grommet. Use a slot screwdriver to snap the retaining clips back in place. Align the power steering pump with its mating surface against the block, and run the bolts in on the end of the extension by hand.

Tighten the bolts with the ratchet wrench. Locate the reservoir on the body of the power steering pump. Remove the nut that is connecting the pulley to the engine and power steering pump using the wrench. Place the drain container below the power steering pump reservoir. Remove the nut on the hose that is connected to the power steering pump and allow the fluid to drain. The power steering pump is on the driver side of the engine compartment, and a plastic reservoir is connected to the top of the pump containing the power steering pump fluid.

Instead, use cleaning products like brake cleaner or carb cleaner and make sure to allow evaporation time. Next, rinse the reservoir screen with fresh power steering fluid. Finally, replace the reservoir o-ring to further prevent leaks. Slip the ring over the two-piece adapter to keep it together. Use one wrench to hold the flanged nut, and another to turn the hex head of the puller bolt. The special puller consists of a split-ring flanged adapter, a ring, a puller bolt, and a puller nut with a flange.

Slide the smooth end of the puller bolt into the hole in the pump shaft, and run the nut down to the pulley. Then place the two-piece adapter into the pulley groove and over the puller nut flange. The power steering reservoir holds the power steering fluid that makes steering a car very easy and responsive. As the power steering fluid leaks out from the reservoir there is less in the pump to operate the steering mechanisms.

Sometimes the leaking will be caused by a power steering hose that is connected to the fluid reservoir. Check this before you remove the reservoir. If the leak is coming from a particular connection, replace that entire hose as well as the reservoir.

Step 5: Remove the hose clamp from the return hose. You can simply remove the power steering belt and the vehicle will still work. The steering will be very heavy compared to with the power assist. This is because of the rack ratio being optimized for power steering along with caster angles, etc.

I have had cars with and without power steering. Turn the bolts counterclockwise to remove them. Pull the power steering pump free from the engine compartment. Locate the two metal snap flanges on each side of the reservoir. Use a slot screwdriver to pry them apart and pull the reservoir out of the pump body.

Instructions on how to replace the power steering pump or the power steering reservoir on Mercedes Benz V6 and V8 cylinder engines, such as the M and M engines. Symptoms of Power Steering Failure are: We recommend that before you go and replace a power steering pump make sure that you have not lost power steering fluid.

The bottom of the power steering fluid reservoir will be attached to a hose that runs to the power steering pump.
