Power Steering Reservoir

Remove and replace the power steering fluid reservoir on a 1992 Dodge Viper 8.0L V10, including draining the system and refilling with proper fluid.

Warnings

Tools required

Parts

• Power steering reservoir (if damaged) × 1 — Use OEM specification
• Hose clamps (if corroded or damaged) × 2 — Use OEM specification

Fluids

• Mopar power steering fluid or ATF+3 — 1.5 qt

Preparation

1. Park vehicle on level ground and set parking brake.
2. Allow engine to cool completely if recently operated.
3. Place drain pan beneath work area to catch fluid.
4. Gather all tools and replacement parts before beginning.

Procedure

1. 1

   Drain the Reservoir
   Use a turkey baster, syringe, or similar tool to remove as much fluid as possible from the reservoir. Transfer fluid to drain pan. This minimizes spillage during hose removal.
2. 2

   Disconnect the Return Hose
   Locate the lower return hose on the reservoir (typically the larger diameter hose coming from the steering gear). Use hose clamp pliers or flat blade screwdriver to loosen the spring clamp or worm-drive clamp securing the hose. Slide the clamp back away from the reservoir neck. Twist and pull the hose off the reservoir fitting. Be prepared for residual fluid to drain. Direct the hose into the drain pan.
3. 3

   Disconnect the Pressure Supply Line
   Identify the upper supply line (typically the smaller metal line or high-pressure hose from the pump). Identify the supply/pressure line connection. Verify whether it uses a threaded fitting or a clamped hose at the reservoir on this vehicle. If threaded, loosen the fitting with the correct size line wrench (verify size against factory service manual). Remove the line completely and cap or plug the open end to prevent contamination. Allow any residual fluid to drain into the pan.
4. 4

   Remove Reservoir Mounting Hardware
   The reservoir is secured to the inner fender or bracket with mounting hardware (verify exact bolt count and head size against the factory service manual). Remove the mounting bolts completely with the correct size socket. Keep the bolts and any washers or spacers for reinstallation.
5. 5

   Remove the Reservoir
   Lift the reservoir up and out of the engine bay. Tilt as needed to drain any remaining fluid into the drain pan. Inspect the reservoir for cracks, damage, or contamination. Check the condition of the internal filter screen if visible through the filler neck.
6. 6

   Prepare the New or Cleaned Reservoir
   If reusing the original reservoir, clean it thoroughly with power steering fluid or mineral spirits. Inspect all fittings and ports for damage. If installing a new reservoir, verify it matches the original in fitting locations and hose connections. Ensure the filter screen is installed if equipped.
7. 7

   Install the Reservoir
   Position the reservoir into its mounting location on the inner fender or bracket. Align the mounting holes and start both mounting bolts by hand. Tighten the 2 mounting bolts with a 10mm socket to secure the reservoir. Ensure the reservoir is stable and properly seated before proceeding.
8. 8

   Reconnect the Pressure Supply Line
   Install a new O-ring on the pressure line fitting if applicable. Thread the pressure line into the reservoir port by hand to avoid cross-threading. Tighten the pressure line fitting to the factory-specified torque using the correct size wrench (verify torque value and wrench size against the service manual).

9. 9

   Reconnect the Return Hose
   Push the return hose firmly onto the reservoir neck until it seats completely. Verify the hose is fully engaged. Slide the hose clamp into position approximately 1/4 inch from the end of the hose and tighten securely. If the original clamp is damaged or corroded, replace it with a new worm-drive or spring clamp.
10. 10

    Fill the System
    Pour the manufacturer-specified power steering fluid (Chrysler ATF; the current serviceable equivalent is Mopar ATF+4) into the reservoir through the filler neck until the fluid level reaches the COLD FULL mark. Use a clean funnel to avoid contamination. Do not overfill.
11. 11

    Bleed the System
    With the engine off, turn the steering wheel slowly from lock to lock 10-15 times. Check the fluid level frequently and add fluid as needed to maintain the COLD FULL mark. Start the engine and allow it to idle. Turn the steering wheel slowly from lock to lock 2-3 times while the engine runs. Check for leaks at all connections. Shut off the engine and recheck the fluid level. Top off to the HOT FULL mark if needed.

Reassembly

1. Reassembly is covered in the installation steps above.
2. Ensure all hose clamps are tight and positioned correctly to prevent leaks.
3. Verify fluid level is at HOT FULL mark after bleeding procedure.

Verification

• Start the engine and verify no leaks at the reservoir connections or fittings.
• Turn the steering wheel from lock to lock and confirm smooth operation with no whining or grinding noises.
• Check fluid level after test drive and top off if necessary to HOT FULL mark.
• Inspect the work area beneath the vehicle for any fluid drips or leaks after a short drive.
