Steps
Locate and label the hoses
Allow the engine to cool and locate the solenoid near the passenger-side suspension. Photograph or label all three hose positions before disconnecting anything.
Disconnect the old solenoid
Unplug the electrical connector and release each hose clamp with pliers. Gently twist hoses free at accessible ends, noting their routing, then slide the solenoid from its mount.
Transfer hoses and shielding
Move any retained hoses and protective sleeve to the replacement in the same orientation. Check hoses for splits, hardening, or blockage and replace damaged pieces.
Install and verify the replacement
Connect each hose to its recorded fitting, return the solenoid to its bracket, and reconnect the electrical plug. Confirm clamps are seated and wiring is clear, then start the engine and inspect for warning lights or leaks.
Check your vehicle’s repair manual for exact specifications and fit.
