🔧 Acadia - Engine Mount Replacement

Your Acadia uses multiple mounts to hold the engine/transmission in place and control vibration. The exact steps and (critical) torque specs change depending on which mount you’re replacing and whether it’s the engine-side mount or the transmission-side mount.

Difficulty Level: Intermediate | Estimated Time: 1.5-4.0 hours (varies by mount)

⚠️ Safety & Precautions

• ⚠️ Never support the engine by the oil pan without a wide wood block; you can crack the pan.
• ⚠️ Keep hands clear when the engine is supported and bolts are removed; it can shift suddenly.
• ⚠️ Work on level ground and support the vehicle with jack stands; never rely on a floor jack alone.
• ⚠️ If you remove any mount bolts, support the powertrain first to prevent strain on axles/exhaust.
• ⚠️ Battery disconnect is usually not required, but disconnect it if you’ll be near the starter/primary wiring.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
• Open the hood and remove any plastic engine cover by pulling upward (if equipped).
• Plan how you’ll support the powertrain: place a floor jack with a wood block under the engine to hold it up slightly.
• Tip: Lift the engine only enough to remove load.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which mount you’re replacing

• Look for the failed mount location: passenger side (RH engine mount), driver side (LH/transmission mount), or lower mounts (front/rear torque struts).
• Before loosening anything, I need the exact mount position so I can give the correct disassembly path and the correct OEM torque specs.

Step 2: Safely raise and support the vehicle (if access from below is needed)

• Use a floor jack (rated 3-ton minimum) to lift the front at the correct jacking point.
• Set the vehicle onto jack stands (rated 3-ton minimum) and verify it’s stable.

Step 3: Support the engine

• Place the wood block 2x6 on the pad of the floor jack (rated 3-ton minimum).
• Raise the jack until it just contacts the underside of the engine and takes the weight off the mount.
• Tip: Don’t “lift” the SUV—just support the engine.

Step 4: Remove required covers/shields for access

• Use a trim clip removal tool and socket set 8mm-13mm to remove any splash shield/undertray fasteners blocking access.
• If a wheel-well liner section blocks access, use a Torx bit set (T20-T50) and trim clip removal tool to loosen and move it aside.

Step 5: Remove the mount fasteners

• Use the correct socket set 13mm-21mm or E-Torx socket set (specialty) to remove the mount-to-body and mount-to-bracket fasteners.
• If a bolt is tight, use a breaker bar 1/2-inch to crack it loose, then switch to a ratchet.
• Use a pry bar 18-inch only if needed to line up bolt holes during reassembly.

Step 6: Remove the mount and install the new one

• Remove the mount from the vehicle, noting orientation (some mounts only fit one way).
• Set the new mount into place and start all bolts by hand to prevent cross-threading.

Step 7: Set engine height and torque fasteners

• Use the floor jack (rated 3-ton minimum) to raise/lower the engine slightly until bolts thread in smoothly.
• Tighten bolts with a torque wrench 10-200 ft-lbs.
• Torque specs are position-specific on your Acadia and some bolts may be one-time-use. Once you tell me which mount position you’re doing, I’ll give you the exact torque sequence and values.

Step 8: Reinstall shields/liners and lower the vehicle

• Reinstall any splash shields using a socket set 8mm-13mm and Torx bit set (T20-T50).
• Lower the vehicle off the jack stands (rated 3-ton minimum) using the floor jack (rated 3-ton minimum).

✅ After Repair

• Start the engine and let it idle; confirm the engine sits level and doesn’t lift excessively when shifting from Park to Reverse/Drive with your foot on the brake.
• Test drive at low speed first; listen for clunks on acceleration/deceleration.
• Recheck for any loose shields/fasteners after the first drive.

💰 DIY vs Shop Cost

Shop Cost: $450-$1,200 (parts + labor; varies by mount/location)

DIY Cost: $80-$350 (parts only; varies by mount brand/location)

You Save: $250-$850 by doing it yourself!

Shop labor rates vary but typically run $100-$150/hour. This repair takes a shop approximately 1.5-4.0 hours.

I only need 2 quick details to give you the exact mount-by-mount steps and OEM torque specs:

• Which mount are you replacing on your Acadia: passenger-side (RH engine mount), driver-side (LH/transmission mount), or lower front/rear torque mount?
• Are you replacing one mount or doing all mounts?
