The engine in your MINI has to be secured to the chassis in order to provide maximum power transfer. MINI achieves this by using a hydraulic motor mount (liquid filled). These mounts have hollow chambers inside that are filled with fluid that helps to create a stiff engine mount while maintaining the highest level of vibration dampening.

The R56 drivetrain (engine and transmission) is supported by a system of mounts. The engine rests on two engine mounts, one on the right and one at the bottom center near the engine oil pan. At the left side, the transmission rests on a mount, which is bolted to a support bracket.

When an engine mount begins to fail, you will feel more vibrations from the engine. The engine may sag in the engine bay or the engine may have excessive movement under torque if a mount is broken. When working under your vehicle, you may notice fluid leaking out of your engine mount(s). This means the mount has failed and should be replaced.

In this article, I'll go over the steps involved with replacing the engine mounts on the MINI R56 with an Turbocharged 4-cylinder engine. Other engines are similar.

Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve, as they grow older. If something seems different, let us know and share your info to help other users.

Place the radiator support in service mode. See our tech article on radiator support service mode.

The following steps highlight removing the right side engine mount.

The right engine mount (red arrow) is right below the radiator support (green arrow).
Figure 1

The right engine mount (red arrow) is right below the radiator support (green arrow). To remove the right engine mount, the radiator support has to be moved, as it blocks access.

Start by supporting the engine from below using a jack or jack stand and a wood block (green arrow).
Figure 2

Start by supporting the engine from below using a jack or jack stand and a wood block (green arrow). Be sure to evenly spread the weight using the wood block.

Working at the right side of the engine, remove the four 13mm engine mount fasteners (red arrows).

Working at the right side of the engine, remove the four 13mm engine mount fasteners (red arrows).

Next, remove the 13mm ground strap nut (red arrow).
Figure 4

Next, remove the 13mm ground strap nut (red arrow). Be sure to support the stud from below when removing the nut. It is not captured and may fall out. Reinstall the nut to secure the stud so it does not get lost (inset).

Remove the 18mm engine mount nut (red arrow).
Figure 5

Remove the 18mm engine mount nut (red arrow).

Then remove the engine mount support bracket from the engine (red arrow).
Figure 6

Then remove the engine mount support bracket from the engine (red arrow).

Working at the mount, remove the 16mm fastener (red arrow).
Figure 7

Working at the mount, remove the 16mm fastener (red arrow). Then remove the two 13mm fasteners (green arrows).

Lift the mount (red arrow) out of the engine bay and remove it.
Figure 8

Lift the mount (red arrow) out of the engine bay and remove it.

To make getting the mount out easier, you can remove the right side headlight and remove it through the headlight mounting area (red arrow).
Figure 9

To make getting the mount out easier, you can remove the right side headlight and remove it through the headlight mounting area (red arrow).

Before installing the new mount, be sure the mounting surface and holes are clear and clean (red arrows).
Figure 10

Before installing the new mount, be sure the mounting surface and holes are clear and clean (red arrows). Note the sand and dirt on my subject vehicle. Leaving this in place could cause the fasteners to bind or the mount to sit crooked. When installing the mount, install the three fasteners finger tight before tightening. This helps to align the mount to the body. Reverse the remaining steps, and you are done.

Comments and Suggestions:
Mel Comments: Is there any way to just unbolt the two bolts at the rad support by the mount and bend the rad support enough to get a swivel head socket and remove the bolts for the mount? Thanks
