Air Suspension Valve Block

This procedure guides you through the removal and replacement of the air suspension valve block on a 2025 Rivian EDV 500, which controls air distribution to each suspension corner.

Warnings

Tools required

Parts

• Air suspension valve block assembly × 1 — Use OEM Rivian specification
• Valve block O-rings/gasket kit × 1 — Use OEM Rivian specification
• Air line quick-connect fittings (if damaged) × 4 — Use OEM Rivian specification
• Electrical connector seals × 2 — Use OEM Rivian specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Chock rear wheels securely
3. Connect Rivian diagnostic tool and document any existing air suspension fault codes
4. Using diagnostic tool, command air suspension to minimum ride height and disable the system
5. Allow system to fully depressurize (approximately 5 minutes)
6. Disconnect 12V battery negative terminal and wait 15 minutes for system capacitors to discharge
7. Raise vehicle on lift or jack stands to working height with all four corners supported
8. Remove front skid plate or underbody panels to access valve block location (typically forward of rear axle, driver side frame rail)
9. Clean area around valve block to prevent contamination during removal

Procedure

1. 1

   Disconnect electrical connectors
   Locate the two electrical connectors on the valve block assembly. Press the locking tabs and carefully disconnect both connectors. Inspect connector pins for corrosion or damage. Mark connector orientation if not keyed.
2. 2

   Label and photograph air line connections
   Using a smartphone or camera, photograph all air line connections to the valve block from multiple angles. Note which line connects to which port: RF (right front), LF (left front), RR (right rear), LR (left rear), and reservoir inlet. Use masking tape to label each line before disconnection.
3. 3

   Disconnect air lines from valve block
   Press the collar on each quick-connect fitting while pulling the air line straight out. Start with the reservoir line, then proceed to each corner line. Expect a small release of residual air pressure. Cap or plug open ports immediately to prevent contamination. Inspect air lines for cracks, abrasion, or damage.
4. 4

   Remove valve block mounting fasteners
   Remove the mounting bolts securing the valve block to the frame rail bracket. Typically there are 3-4 bolts. Support the valve block with one hand while removing the final fastener to prevent it from falling.
5. 5

   Remove valve block assembly
   Carefully lower the valve block from its mounting location. Route it clear of any wiring harnesses or brake lines. If the block has integrated pressure sensors or solenoids, handle with care to avoid damage. Place the old unit on a clean work surface.
6. 6

   Inspect mounting bracket and surrounding area
   Examine the mounting bracket for cracks, corrosion, or damage. Check frame rail for any signs of moisture intrusion or damage. Clean mounting surface with compressed air or shop vacuum. Verify all mounting bolt threads are clean and undamaged.
7. 7

   Prepare new valve block
   Unpack new valve block assembly and verify it matches the original unit. Install new O-rings or gaskets on all air ports if not pre-installed. Apply a light film of silicone grease to O-rings. Verify electrical connector seals are properly seated.
8. 8

   Install new valve block
   Position the new valve block into the mounting bracket, ensuring proper orientation with ports facing the correct directions per your reference photos. Thread mounting bolts by hand first to ensure proper alignment, then tighten in a cross-pattern. Since no torque specification is provided, tighten bolts firmly and evenly, approximately 15-20 ft-lbs equivalent.
9. 9

   Reconnect air lines
   Starting with the reservoir line, push each air line firmly into its quick-connect fitting until you hear and feel a distinct click. Verify connection by gently pulling on each line - it should not release. Connect all four corner lines according to your labels and reference photos. Double-check each connection matches the documented configuration.
10. 10

    Reconnect electrical connectors
    Align and reconnect both electrical connectors to the valve block, ensuring they fully seat and locking tabs engage. Listen for an audible click. Inspect connectors to verify they are flush against the valve block housing.
11. 11

    Secure wiring and lines
    Ensure all air lines and wiring harnesses are properly routed and secured with existing or new cable ties. Verify no lines or wires contact sharp edges, exhaust components, or moving suspension parts. Check for adequate clearance through full suspension travel.
12. 12

    Reinstall underbody panels
    Reinstall the front skid plate or underbody panels that were removed for access. Verify all fasteners are installed and properly tightened. Check that no wires or hoses are pinched.
13. 13

    Reconnect battery and initialize system
    Reconnect the 12V battery negative terminal. Turn ignition to ON position without starting vehicle. Connect Rivian diagnostic tool and clear any stored fault codes related to air suspension depressurization.
14. 14

    Pressurize and test system
    Using diagnostic tool, command air suspension system to pressurize and perform self-test. Monitor for fault codes. Listen for air leaks around valve block connections. System should pressurize within 2-3 minutes. Command vehicle to normal ride height and verify all corners rise evenly.
15. 15

    Perform system calibration
    With diagnostic tool, perform air suspension ride height calibration procedure per Rivian service software instructions. This typically involves cycling through all ride height settings and allowing system to learn sensor values. Verify calibration completes without errors.

Reassembly

1. Lower vehicle from lift and remove jack stands
2. Perform final visual inspection of valve block area for any disconnected lines or loose fasteners
3. Test drive vehicle at low speed in a safe area, cycling through different ride height modes if equipped
4. After test drive, re-inspect all connections for leaks with vehicle at operating pressure

Verification

• With ignition on, verify no air suspension warning lights are illuminated on instrument cluster
• Using diagnostic tool, verify no active or pending fault codes related to air suspension system
• Command each corner to raise and lower individually if diagnostic tool supports this function - verify proper operation
• Check for air leaks by listening around valve block and connections while system is at full pressure
• Verify ride height matches factory specification (typically displayed in diagnostic tool)
• Test all ride height modes (low, normal, high if equipped) and verify smooth operation without unusual noises
• After 24 hours of normal driving, re-check for fault codes and verify system maintains pressure overnight
