Replacing engine and transmission mounts (Renault Megane 1)

Inspection

1. Set the handbrake, then jack up the front of the car and support it on axle stands. Where fitted, remove the engine undershield.

2. Visually inspect the rubber mounts on the two front and one rear engine/transmission mount brackets for cracks and dirt. Check that all bracket fasteners are securely tightened; use a torque wrench when doing this. If there is excessive movement of the supports or the condition of the rubber cushions has deteriorated, the support should be replaced.

Right front support

Tightening torques (in Nm) for engine/transmission mounts

1. Attach a winch to the engine mounting eyes to support the engine/transmission assembly while the mount is removed. A jack and a suitable block of wood may be used to support the assembly to increase the support area under the pan.

2. On F8Q engines, remove the mounting bolts and the upper plastic drive belt/right engine mount cover. On F9Q engines, remove the mounting nuts and the sound deadening cover.



3. Make sure the engine/transmission assembly is securely supported, then remove the nut securing the upper mount bracket to the ride limiter/rubber mount assembly on the body.



4. Remove the three bolts securing the upper support bracket to the main bracket on the engine, then remove the bracket (refer to the accompanying illustration).

5. Remove the bolts securing the travel limiter/rubber engine mount assembly to the body and remove the assembly.

6. Remove the outer timing belt covers to gain access to the main bracket mounting bolts on the engine. Remove the bolts and remove the main bracket.

7. Install the travel limiter/rubber cushion assembly. On F8Q engines, do not fully tighten the mounting bolts yet.

8. Install the upper bracket and tighten its bolts to the specified Specifications force. On F8Q engines, do not fully tighten the nut securing the bracket to the travel limiter/rubber pad assembly yet.

9. Remove the winch or jack.

10. On F8Q engines, the travel limiter/rubber pad assembly now needs to be centered before tightening the mounting bolts (on engines - self-centering assembly). Renault technicians use a special forked grip Mot. 1289-03, which is inserted through the slots in the bracket. If this tool is not available, it can be made from metal strips.



11. After centering the support, tighten its mounting nut to the specified Specifications by effort (refer to the accompanying illustration). Remove the tool and install the plastic cover or engine cover where available.

Front left support

1. Remove the left wheel.

2. Using a jack and a block of wood, support the weight of the transmission.

3. Loosen the nut that secures the lower mount post to the upper bracket. Tap the post with a mallet to release it from the upper bracket.



4. Unscrew the rubber part of the upper mount and the bracket (refer to the accompanying illustration).

5. Unscrew the lower mounting bracket.

6. Install new fasteners in the reverse order of removal and tighten the strut, nuts and bolts to the torque shown in the illustration above (Engine/Transmission Mount Tightening Torques (Nm)).

Rear support

1. Remove the air cleaner assembly as described in Chapter Power and exhaust systems.

2. Working in the engine compartment, on the lower left side of the engine, remove the nuts from the bolts securing the rear mount bracket to the transmission. At the same time, remove the shock absorber from the top of the mount.



3. Using a winch or jack with a wooden block, slightly raise the engine to remove the load from the rear mount.



4. Remove the bolts from the bracket and separate the bracket from the transmission and subframe (refer to the accompanying illustration).

5. Install the new mount in the reverse order of removal and tighten the bolts to the torque shown in the illustration above (Engine/Transmission Mount Tightening Torques (Nm)).
