Engine Mount Check

  1. Disconnect upper vacuum hose from engine mount control solenoid valve. Install a hand-held vacuum pump to upper vacuum hose. Apply 20 in. Hg vacuum. If vacuum holds, go to next step. If vacuum does not hold, check vacuum hose for leaks. If vacuum hose is okay, go to next step.
  2. Release and reapply vacuum several times. If idle vibration does not change with or without vacuum applied, replace engine mount. If idle vibration changes noticeably with or without vacuum, test engine mount control solenoid valve and vacuum supply. See ENGINE MOUNT CONTROL SOLENOID VALVE TEST .
