Warnings

Tools required

Parts

• Air suspension valve block assembly × 1 — Use OEM Rivian specification
• Valve block mounting gasket × 1 — Use OEM Rivian specification
• Air line push-connect fittings (if damaged) × 4 — Use OEM Rivian specification
• Wiring harness connector seals (if damaged) × 1 — Use OEM Rivian specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Ensure air suspension is in normal ride height mode (not raised or lowered)
3. Connect Rivian diagnostic scanner and verify communication with suspension control module
4. Open rear cargo area and remove rear interior floor panels to access valve block location
5. Disconnect 12V auxiliary battery negative terminal and wait 5 minutes
6. Using diagnostic scanner, navigate to air suspension module and initiate 'Valve Block Service Mode'
7. Execute 'Depressurize All Corners' command and wait for system to fully exhaust (approximately 3-5 minutes)
8. Verify zero pressure reading on all four suspension corners via diagnostic tool
9. Document any active fault codes before beginning disassembly

Procedure

1. 1

   Access the valve block assembly
   The valve block is located in the rear cargo area beneath the floor panel on the driver side. Remove the cargo floor carpet and rigid floor panel. Remove the four plastic clips securing the sound dampening material covering the valve block area. The valve block is mounted to the frame rail with a metal bracket.
2. 2

   Disconnect electrical connectors
   Locate the main wiring harness connector on the valve block. Press the red locking tab and slide it upward to unlock position. Squeeze the connector release tabs on both sides and pull straight away from the valve block. Inspect connector for corrosion or damage. Mark connector orientation with tape if needed for reference.
3. 3

   Disconnect air supply line from compressor
   Locate the main air supply line (largest diameter, typically 10mm) coming from the air compressor. Press the push-connect fitting collar inward while pulling the air line straight out. Use a slight twisting motion if line is difficult to remove. Inspect the O-ring inside the fitting for damage. Cap the compressor outlet with clean shop towel to prevent contamination.
4. 4

   Disconnect air lines to suspension corners
   Disconnect the four air lines running to each wheel corner from the valve block. Lines are color-coded or labeled: LF (left front), RF (right front), LR (left rear), RR (right rear). Press each push-connect collar and remove the line. Mark each line with tape labels to ensure correct reconnection. Inspect fittings for any cracks or damage.
5. 5

   Disconnect exhaust/vent line
   Locate the exhaust vent line (smallest diameter line) that routes to the chassis vent. Disconnect using the same push-connect method. This line allows the system to exhaust air during lowering operations. Verify the line is clear of obstructions.
6. 6

   Remove valve block mounting hardware
   Remove the three mounting bolts securing the valve block bracket to the frame rail using 13mm socket. Support the valve block assembly with one hand while removing the final bolt to prevent it from dropping. Remove the valve block and bracket assembly from the vehicle. Note the orientation of any spacers or washers.
7. 7

   Remove valve block from mounting bracket
   Place the valve block assembly on a clean work surface. Remove the four Torx T30 screws securing the valve block to the mounting bracket. Remove the old gasket or seal from the mounting interface. Clean the mounting bracket surface with a clean shop towel to remove any debris or old gasket material.
8. 8

   Prepare new valve block for installation
   Remove the new valve block from packaging carefully. Verify part number matches the original component. Remove protective caps from all ports. Install the new mounting gasket onto the valve block, ensuring proper alignment with mounting holes. Check that all solenoid ports are free of shipping plugs or debris.
9. 9

   Mount new valve block to bracket
   Position the new valve block onto the mounting bracket with gasket in place. Align all four mounting holes. Install the four Torx T30 screws and tighten in a cross-pattern to ensure even gasket compression. Tighten to finger-tight plus 1/4 turn or until gasket is evenly compressed (typically 8-10 Nm).
10. 10

    Install valve block assembly to vehicle
    Position the valve block and bracket assembly to the frame rail mounting location. Ensure proper orientation with ports facing toward their respective air lines. Install the three 13mm mounting bolts with any spacers or washers in original locations. Tighten bolts in a progressive pattern, final torque to be snug plus additional 1/4 turn (estimated 35-45 Nm).
11. 11

    Reconnect air lines to valve block
    Reconnect all air lines to their respective ports following the labels applied during removal: main supply line from compressor, four corner lines (LF, RF, LR, RR), and exhaust vent line. Push each line firmly into the push-connect fitting until it clicks and is fully seated. Gently pull on each line to verify secure connection. Ensure no lines are kinked or under tension.
12. 12

    Reconnect electrical connector
    Align the main wiring harness connector with the valve block connector, ensuring correct orientation. Push the connector straight onto the valve block until it clicks into place. Slide the red locking tab down to the locked position. Verify connector is fully seated with no gaps visible.
13. 13

    Perform system pressurization and leak test
    Reconnect the 12V auxiliary battery negative terminal. Connect diagnostic scanner and verify communication with suspension control module. Navigate to air suspension service functions and select 'Exit Service Mode'. Execute 'System Pressurization Test' which will charge all corners to target pressure. Monitor pressure readings on scanner during fill cycle (approximately 5-8 minutes). Listen for any audible air leaks around valve block and air line connections.
14. 14

    Perform valve block calibration
    Using diagnostic scanner, navigate to air suspension calibration menu. Select 'Valve Block Replacement Calibration'. Follow on-screen prompts which will cycle each solenoid valve through multiple open/close sequences to establish baseline operation. This process takes approximately 10 minutes. Do not interrupt the calibration process. Verify calibration completes successfully with no fault codes.
15. 15

    Perform functional test and clear codes
    Using diagnostic scanner, command the suspension through full range of motion: raise to maximum height, lower to minimum height, return to normal ride height. Verify all four corners respond correctly and maintain pressure. Clear any stored fault codes from the suspension module. Perform a final system leak test by monitoring pressure decay over 5 minutes with system off - pressure drop should be less than 5 PSI across all corners.

Reassembly

1. Reinstall sound dampening material and secure with plastic clips
2. Reinstall rigid floor panel and cargo floor carpet in rear cargo area
3. Verify all air lines are properly routed and secured away from sharp edges and moving components
4. Ensure no tools or parts were left in the cargo area
5. Double-check all electrical connections are locked and secure

Verification

• Start the vehicle and verify no air suspension warning lights are illuminated on instrument cluster
• Using diagnostic scanner, verify no active or pending fault codes in suspension control module
• Test all suspension height modes (normal, raised, lowered) and verify proper operation
• Drive vehicle at low speed and verify suspension responds correctly to load changes
• Perform overnight pressure hold test: park vehicle overnight and check that all corners maintain pressure with less than 10 PSI loss over 8 hours
• Verify suspension automatically levels when vehicle is loaded with cargo or passengers
• Listen for any abnormal compressor cycling or air leaks during normal operation
