DIAGNOSIS
A Civic with the R18A1 engine is shown in the photograph. The diagnosis is the same for all other Civic engine types.
1. Visually inspect the passenger's side engine mount for tearing or leaking.
^
If the engine mount is torn or leaking fluid, go to REPAIR PROCEDURE, no test drive is needed.
^
If the engine mount is not torn or leaking fluid, and the vehicle is within the affected VIN range for a cavitating engine mount, go to step 2.
^
If the engine mount is not torn or leaking fluid, and the vehicle is not within the affected VIN range for a cavitating engine mount, this service
bulletin does not apply; proceed with normal troubleshooting.
2. Place a wood block onto a floor jack, and position it under the oil pan at the end closest to the passenger's side engine mount. Raise the engine
enough to insert the diagnostic spacer between the side engine mount and the bracket. Be sure to leave the spacer sticking out about 1/2 inch so it can
be easily removed. Remove the floor jack.
