Engine Mount Diaphragm Actuator Check

Disconnect vacuum hose from solenoid valve. Clean and oil diaphragm actuator rod, rear mount rotor lever, and lever linkage. Using a hand-held vacuum pump, apply about 9 in. Hg to actuator diaphragm. See Fig 1. Actuator rod should move smoothly and diaphragm should hold vacuum. Replace as necessary.
