🔧 Outback - Engine Mount Replacement

Engine mounts (also called insulators) hold the engine in place and absorb vibration. When they crack or collapse, you’ll feel extra shaking, clunks on acceleration/braking, or the engine may shift more than normal.

Difficulty Level: Advanced | Estimated Time: 3-6 hours

Assumption: replacing the left & right engine mounts (not the transmission mount).

⚠️ Safety & Precautions

• ⚠️ Support the engine before unbolting mounts; don’t rely on a jack alone.
• ⚠️ Use jack stands; never work under a car supported only by a floor jack.
• ⚠️ Keep hands clear when raising/lowering the engine; pinch hazard.
• ⚠️ Do not jack directly on the oil pan without a wood block; you can crack it.
• ⚠️ Let the exhaust cool fully; burns happen fast.
• ⚠️ Battery disconnect is recommended if you’ll be near the starter/positive cable: use a 10mm wrench and remove negative terminal first.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels.
• Open the hood and remove any loose items from the engine bay.
• If disconnecting the battery: use a 10mm wrench and remove the negative terminal first.
• Plan how you will support the engine:
  • Engine support bar (specialty) spans the fenders and holds the engine from above.
  • If using a floor jack: place a wood block on the jack pad to spread the load.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the Outback

• Use a floor jack to lift the front at the center jacking point.
• Set the vehicle onto jack stands at the proper pinch weld/support points.
• Give the car a firm push test to confirm it’s stable.

Step 2: Remove the lower engine splash shield

• Use a trim clip remover and flathead screwdriver to remove plastic clips.
• Use an 8mm socket or 10mm socket (varies by fastener) to remove bolts.
• Set the shield and fasteners aside in a tray.

Step 3: Support the engine

• Preferred: Install the engine support bar (specialty) per its instructions and put light tension on the engine.
• Alternate: Position the floor jack with a wood block under the engine’s lower support area and raise until it just contacts and supports the engine.
• Only lift enough to remove mount tension.

Step 4: Remove the pitch stopper (top dogbone mount)

• The pitch stopper is the small “dogbone” link on top that limits engine rocking.
• Use a 14mm socket and ratchet to remove the two bolts.
• Set it aside.
• Torque on install: Torque to 50 Nm (37 ft-lbs)

Step 5: Loosen the engine mount-to-subframe nuts (both sides)

• From underneath, locate the mount studs going down into the front subframe/crossmember.
• Use a 14mm deep socket with an extension to loosen (do not fully remove yet).

Step 6: Remove the engine mount-to-engine bracket nuts/bolts (as equipped)

• On each side, access the mount fasteners that attach the mount to the engine-side bracket.
• Use a 14mm socket, extensions, and a universal joint socket adapter as needed.
• Remove the fasteners and keep left/right hardware separated.

Step 7: Lift the engine slightly to free the mounts

• Use the floor jack (or tighten the engine support bar) to raise the engine slowly.
• Watch clearance at the radiator fans, exhaust, and hoses while lifting.
• Stop as soon as the mount studs clear the subframe holes.

Step 8: Remove the old engine mounts

• Finish removing the mount-to-subframe nuts using a 14mm deep socket.
• Work each mount out. Use a pry bar gently if needed (don’t pry on aluminum surfaces).
• Compare old vs new mounts so the orientation matches.

Step 9: Install the new engine mounts (left & right)

• Position the new mounts in the same orientation as the originals.
• Lower/raise the engine slightly using the floor jack so the studs line up with the subframe holes.
• Start all nuts/bolts by hand first to avoid cross-threading.

Step 10: Tighten and torque the mount fasteners

• Snug all mount fasteners using a ratchet before final torque.
• Final tighten using a torque wrench:
  • Engine mount-to-subframe nuts: Torque to 50 Nm (37 ft-lbs)
  • Engine mount-to-engine bracket fasteners: Torque to 50 Nm (37 ft-lbs)
• If any fasteners call for it, apply threadlocker (medium strength) to clean threads before torquing.

Step 11: Reinstall the pitch stopper

• Install the pitch stopper and start both bolts by hand.
• Use a 14mm socket and torque wrench.
• Torque: Torque to 50 Nm (37 ft-lbs)

Step 12: Reinstall the splash shield and lower the vehicle

• Reinstall the shield using the trim clip remover, 8mm socket, and 10mm socket as needed.
• Lower the vehicle off the jack stands using the floor jack.

Step 13: Reconnect the battery (if disconnected)

• Use a 10mm wrench to reconnect the negative terminal.

✅ After Repair

• Start the engine and let it idle. Listen for new noises and watch for excessive engine movement.
• With the brake firmly held, shift from Park to Reverse to Drive and feel for clunks (keep RPM low).
• Take a short road test and re-check for vibrations at idle and during light acceleration.
• Recheck the mount fasteners for tightness after 1-2 days of driving.
