Steps
Disconnect power and remove the filter tray
Disconnect the negative battery cable. Remove the cabin filter and release the rear engine-bay tray fasteners, moving the wiring retainer aside to reach the solenoid area.
Remove the old solenoid
Remove the engine cover and disconnect the breather hose and solenoid plug. Turn the solenoid carefully to release it from the valve cover opening.
Install the replacement solenoid
Lightly lubricate the new seal with clean engine oil and seat the solenoid squarely. Tighten it securely without overtightening, reconnect its plug and breather hose, then refit the cover.
Restore the filter tray and battery
Reinstall the cabin filter tray, wiring retainer, filter, and cover. Reconnect the negative battery cable and check for oil seepage after startup.
Check your vehicle’s repair manual for exact specifications and fit.
