Inspection
1. Apply the handbrake, then jack up the front of the vehicle and place it on axle stands. Where available, remove the lower engine cover.
2. Visually inspect the rubber pads on the two front and one rear engine/transmission mounts for cracks and debris. Check that the fasteners of all brackets are securely clamped; when doing this, use a torque wrench. If there is excessive movement of the bearings or the condition of the cushion rubber has deteriorated, the bearing should be replaced.
Right front support
Tightening torques (in Nm) engine/transmission mounts
A - Tighten the strut to 60 Nm
B - Tighten the nut to 40 Nm
1. Attach a winch to the engine mounting lugs to support the engine/transmission assembly while the support is removed. A jack and a suitable piece of wood can be used to support the assembly to increase the area of support under the pallet.
2. On F8Q engines, unscrew the mounting bolts and remove the upper plastic cover of the drive belt / right engine mount. On F9Q engines, unscrew the fixing nuts and remove the soundproof cover.
3. Ensure that the engine/gearbox assembly is securely supported, then remove the nut securing the upper support bracket to the motion limiter/rubber cushion 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 accompanying illustration).
5. Remove the bolts securing the motion limiter/rubber engine mount assembly to the body and remove the assembly.
6. Remove the outer timing belt covers to access the main bracket mounting bolts on the engine. Loosen the bolts and remove the main bracket.
7. Install the motion limiter/rubber cushion assembly. On F8Q engines, do not completely tighten the mounting bolts yet.
8. Install the top bracket and tighten its bolts to Specifications effort. On F8Q engines, do not fully tighten the nut securing the bracket to the travel limiter/rubber cushion assembly yet.
9. Remove winch or jack.
10. On F8Q engines, the travel limiter/rubber pad assembly must now be centered before the mounting bolts can be tightened (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. Having centered a support, tighten its fastening nut given in Specifications effort (refer to accompanying illustration). Remove tool and install plastic cover or engine cover where available.
Front left support
1. Remove the left wheel.
2. Using a jack and block of wood, support the weight of the transmission.
3. Remove the nut securing the bottom mount post to the top bracket. Hit the post with a mallet to release it from the top bracket.
4. Unscrew the rubber part of the top mount and the bracket (refer to accompanying illustration).
5. Unscrew the bottom mounting bracket.
6. Install the new fasteners in the reverse order of removal and tighten the strut, nuts and bolts to the torque shown in the illustration above (Tightening torques (in Nm) engine/transmission mounts).
Rear support
1. Remove the air filter 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 support bracket to the transmission. At the same time, unscrew the shock absorber from the top of the support.
3. Using a winch or jack with a block of wood, slightly raise the engine to take the load off the rear support.
4. Remove the bolts from the bracket and separate the bracket from the transmission and subframe (refer to accompanying illustration).
5. Install the new bearing in the reverse order of removal and tighten the bolts to the torque shown in the illustration above (Tightening torques (in Nm) engine/transmission mounts).
