🔧 CX-5 - Engine Mount Replacement

On your CX-5, the engine is held in place by multiple mounts (right/passenger-side engine mount, left/driver-side transmission mount, and a rear mount). Replacing a mount is very doable DIY, but the exact steps and torque specs change depending on which mount you’re doing.

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

⚠️ Safety & Precautions

• ⚠️ Never get under the CX-5 supported only by a jack—use jack stands.
• ⚠️ The engine must be supported before any mount bolts come out (otherwise it can drop/shift).
• ⚠️ Keep hands clear between the engine and body while jacking/supporting.
• ⚠️ Let the exhaust/catalyst cool fully before working near the rear mount area.
• ⚠️ Battery disconnect is typically not required, but keep tools away from the positive terminal.

📋 Before You Begin

• Park on level ground, shift to 1st gear, and set the parking brake.
• Chock the rear wheels with wheel chocks.
• Plan how you’ll support the engine:
  • Engine support bar = safest; it holds the engine from above.
  • Floor jack + wood block = supports from below; the wood spreads load on the oil pan.
• Two quick questions so I give you the exact mount procedure + correct torque specs:
  • Which mount are you replacing: right (passenger) engine mount, left (driver) transmission mount, or rear mount?
  • Will you support the engine with an engine support bar or a floor jack + wood block?

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and secure the CX-5

• Use a floor jack (rated 3-ton minimum) to lift the front at the center jacking point.
• Place jack stands (rated 3-ton minimum) at the left and right front support points.
• Give the CX-5 a firm push to confirm it’s stable.

Step 2: Remove the lower splash shield (undercover)

• Use a trim clip removal tool and Phillips screwdriver to remove clips/screws.
• Use a socket set 8mm-19mm with a ratchet 3/8" to remove any bolts.
• Set the shield and fasteners aside in order. Lay bolts in a simple pattern.

Step 3: Support the engine

• If using an engine support bar (specialty), install it across the strut towers and tension it to hold the engine weight (follow the support bar’s instructions).
• If using a floor jack (rated 3-ton minimum):
  • Place the wood block 2x6 on the jack pad.
  • Jack up gently under the oil pan area just until you see the engine weight is supported (do not lift the vehicle off the stands).

Step 4: Remove the mount (mount-specific)

• Once you tell me which mount (right/left/rear), I’ll give the exact bolt locations, access steps (air box/battery tray, brackets, etc.), and the correct sequence.
• Use a socket set 8mm-19mm, extensions 3" and 6", and a universal joint adapter as needed for tight access.
• Break tight bolts loose with a breaker bar 1/2" (controlled force).

Step 5: Install the new mount and align the engine

• Start all mount bolts by hand using a socket set 8mm-19mm and ratchet 3/8" (prevents cross-threading).
• Adjust engine height slightly with the floor jack or engine support bar until the bolts thread in smoothly. If it binds, adjust height.
• Tighten using a torque wrench 10-200 Nm range to the correct factory specs.
• Torque to OEM spec (I’ll provide the exact Nm/ft-lbs once you confirm which mount).

Step 6: Reinstall shields and lower the CX-5

• Reinstall the splash shield using a trim clip removal tool, Phillips screwdriver, and socket set 8mm-19mm.
• Lower the CX-5 off the stands using the floor jack.
• Remove wheel chocks.

✅ After Repair

• Start the engine and let it idle; listen for clunks or vibration changes.
• With the hood open, lightly blip the throttle and watch for excessive engine rocking (a little movement is normal).
• Test drive around the block and recheck for any new noises on acceleration/deceleration.
• Recheck mount fasteners with a torque wrench 10-200 Nm range after a short drive if the service info calls for it.
