Engine Mount: Service and Repair

Engine Mounts, 3.OL EFI Engine






Insulator RH Front No.2 and/or RH Rear No.3

Removal

1. Raise vehicle on hoist.

2. Place jack and wood block in suitable place under engine block.

3. Remove nuts retaining RH front and RH rear insulators to frame.

4. Raise engine with jack (enough to unload insulator).

5. Remove two bolts from No.3 insulator and one bolt from No.2 insulator and remove insulator from engine bracket.






Installation - with original hardware

1. Attach insulator-to-engine support bracket with two bolts on No.3 insulator. Tighten bolts to 54-75 Nm (40-55 lb-ft).

Attach bolt to No.2 insulator. Tighten bolt to 164-173 Nm (120-127 lb-ft). Refer to illustration under Removal Step 5

2. Lower engine down onto frame.

3. In stall nuts retaining RH front and RH rear insulators to frame. Tighten nuts to 75-102 Nm (56-75 lb-ft).

4. Remove jack and lower vehicle.

Installation - with updated hardware per TSB 94-12-6 (stepped bolt)

1. Attach insulator-to-engine support bracket with two bolts on No.3 insulator. Tighten bolts to 54-75 Nm (40-55 lb-ft).

Attach bolt to No.2 insulator. A new bolt (F3DZ-6047-A) MUST be used to attach the right front engine mount upper bracket to the A/C bracket, Figure 1.










Tighten the new bolt/washer assembly to 115 lb-ft (156 Nm), using a non-ratcheting torque wrench.

NOTE: BECAUSE OF THE "STEPPED" DESIGN OF THE NEW BOLT, TORQUE WILL RISE IN A "STEPPING" PATTERN, FIGURE 2. INCREASE TORQUE TO 115 LB-FT (156 Nm), AND STOP. IF TORQUE THEN FALLS OFF DUE TO THE BOLT RECEDING INTO A STEP, TIGHTEN UNTIL 115 LB-FT (156 Nm) TORQUE IS ACHIEVED, BEING CAREFUL THAT THE TORQUE FALL-OFF CONDITION DOES NOT RECUR. IT MAY BE NECESSARY TO SLIGHTLY EXCEED SPECIFIED TORQUE IN ORDER TO ACHIEVE CORRECT CLAMP LOADING AFTER TIGHTENING FORCE IS RELEASED. Refer to illustration under Removal Step 5

2. Lower engine down onto frame.

3. In stall nuts retaining RH front and RH rear insulators to frame. Tighten nuts to 75-102 Nm (56-75 lb-ft).

4. Remove jack and lower vehicle.

Insulator LH and Support Assembly No. 1A

Removal

1. Raise vehicle on hoist.

2. Remove LH tire and wheel.

3. Place jack and wood block in suitable place under transaxle and support transaxle.

4. Remove two nuts retaining insulator to support assembly.

5. Remove two through bolts retaining insulator to frame.






6. Raise transaxie with jack (enough to unload insulator).

7. Remove bolts retaining support assembly to transaxle.

8. Remove transaxle support assembly by rotating support assembly counterclockwise to disengage upper stud on mount.

9. Remove mount.






Installation

1. Loosely install mount.

2. Attach support assembly to transaxle. Tighten bolts to 54-75 Nm (40-55 lb-ft). Refer to illustration under Removal Step 8.

3. Attach insulator to frame with two through bolts. Tighten bolts to 81-116 Nm (60- 85 lb-ft).

4. Lower transaxle (enough to load insulator).

5. Attach insulator to support assembly with two nuts. Tighten nuts to 74-102 Nm (55-75 lb-ft). Refer to illustration under Removal Step 5.

6. Attach damper shafi to support assembly using a new flag nut. Tighten bolt to 28- 41 Nm (21-30 lb-ft).

7. Removejack.

8. Install LH tire and wheel. Tighten wheel lug nuts to 115-142 Nm (85-105 lb-ft).

9. Lower vehicle.
