Engine-Support Fasteners Check (Noise Emission Control)

4700 mm 01.04.001

Front and rear engine supports for vehicles built from January 2007 require no periodic maintenance. Mounts should be inspected when the engine is removed for service. For vehicles manufactured prior to January 2007, perform the following check.

Check the rear engine-support fasteners (see Fig., Ref. 3) for tightness. Tighten the 5/8-inch fasteners 150 to 180 lbf·ft (203 to 244 N·m).

  1. Transmission Housing

  2. Transmission Nodal Mount Bracket

  3. Bolt, 5/8–18 x 4

  4. Frame Bracket

  5. Nut, 5/8–18

  6. Lower Isolator

  7. Upper Isolator

Fig. 1, Rear Engine-Support

Check the front engine-support fasteners for tightness. Tighten the 3/4-inch fasteners 260 to 310 lbf·ft (350 to 420 N·m).

Note: At engine overhaul, and whenever the engine has been removed, inspect the lower and upper isolators (Refs. 6 and 7), and replace them if they are worn.
