Engine Mount Sag Measurement Procedure
1. Inspect the vehicle to see if current top engine mount is a first or second design mount. Refer to the following illustrations.^ If the mount is first design, proceed to step 2 of this procedure. If the mount is second design, proceed to step 3 of this procedure.
IMPORTANT:
The measurement procedure in step 2 of this procedure can be used to measure sag on both first and second design engine mounts. However, the measurement procedure in step 3 can only be used for the second design mount.
2. Using two 150 mm (6 in.) scales or a 150 mm (6 in.) scale and a suitable straight edge, measure engine mount assembly as shown in the First Design Mount illustration.
^ If measurement is equal to or less than 39 mm (1-17/32 in.), proceed to "Engine Mount Assembly Removal Procedure" in this bulletin and replace engine mount assembly.
^ If measurement is greater than 39 mm (1-17/32 in.), engine mount assembly does not require replacement.
3. Measure gap in mount at location shown in the Second Design Mount illustration. A 2 mm (5/64 in.) allen wrench or hex key can be used as a go/no go gauge for this measurement.
^ If tool does not fit in gap, proceed to "Engine Mount Assembly Removal Procedure" in this bulletin and replace engine mount assembly.
^ If tool fits in gap, engine mount assembly does not require replacement.
