🔧 Canyon - Engine Mount Replacement

Worn engine mounts let the engine move too much. This can cause clunks on acceleration/braking, vibration at idle, and uneven drivetrain alignment. The job is mostly about safely supporting the engine, then swapping the mounts one at a time.

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

Assumption: replacing both left and right engine mounts; access varies by drivetrain/options.


⚠️ Safety & Precautions

  • ⚠️ Never get under a vehicle supported only by a jack; use jack stands.
  • ⚠️ Support the engine before loosening mount bolts; the engine can drop/shock-shift.
  • ⚠️ Keep hands clear between mount brackets and frame while lifting/lowering the engine.
  • ⚠️ Let the exhaust cool fully; mounts sit near hot components.
  • ⚠️ If you remove the battery/positive cable for access, disconnect negative battery cable first.

🔧 Required Tools

You'll need the following tools for this repair:

  • Floor jack (rated 3-ton minimum)
  • Jack stands (pair, rated 3-ton minimum)
  • Wheel chocks
  • Safety glasses
  • Mechanic gloves
  • Wood block (2x6 or 2x8, 12-18 in. long)
  • Metric socket set 10mm-21mm
  • Metric wrench set 10mm-21mm
  • 1/2 in. drive breaker bar
  • 1/2 in. drive torque wrench (20-200 ft-lbs range)
  • Ratchet extensions (3 in., 6 in., 12 in.)
  • Universal swivel joint adapter
  • Trim clip removal tool
  • Flathead screwdriver
  • Pry bar (12-18 in.)
  • Engine support bar (specialty)

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Right engine mount - Qty: 1
  • Left engine mount - Qty: 1
  • Engine mount fastener kit (recommended) - Qty: 1

📋 Before You Begin

  • Park on level ground, set the parking brake, and place wheel chocks behind the rear tires.
  • Open the hood and remove the engine cover (pull upward by hand if equipped).
  • If the battery area blocks access on your Canyon, disconnect the battery: use a 10mm socket to remove the negative (-) terminal first.
  • Get your lifting plan ready: either use an engine support bar (specialty) from above, or a floor jack with a wood block under the oil pan. (The wood spreads the load so you don’t dent the pan.)

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the truck

  • Use a floor jack at the front jacking point to lift the front end.
  • Place jack stands under the frame and lower onto the stands.
  • Give the truck a firm shake to confirm it’s stable.

Step 2: Support the engine safely

  • Position the floor jack under the engine oil pan with the wood block between the jack and pan.
  • Jack up just until the wood touches and slightly supports the engine weight.
  • Tip: only lift 1-2 mm at a time.

Step 3: Create access to the right (passenger-side) engine mount

  • Remove the air intake duct/box if it blocks access: use a flathead screwdriver for hose clamps and a 10mm socket for bolts.
  • If any wiring harness clips are attached near the mount area, release them using a trim clip removal tool.

Step 4: Remove the right engine mount fasteners

  • Locate the right mount between the engine bracket and the frame bracket.
  • Use a ratchet with extensions and the correct metric socket to loosen (do not fully remove yet) the mount-to-frame bolts/nuts.
  • Use the correct metric socket to loosen the mount-to-engine bracket bolts/nuts.
  • Now raise/lower the engine slightly with the floor jack to remove tension, then fully remove the fasteners.
  • Torque: Torque to OEM spec (varies by mount/fastener set)

Step 5: Remove and replace the right engine mount

  • Work the mount out by hand; if stuck, use a pry bar gently against the bracket (do not pry on plastic parts).
  • Install the new mount in the same orientation.
  • Start all bolts/nuts by hand first to avoid cross-threading.
  • Use a ratchet to snug all fasteners, but do not final-torque yet.

Step 6: Create access to the left (driver-side) engine mount

  • If the battery and tray block access on your Canyon, remove them: use a 10mm socket for terminals/hold-down and a 13mm socket (common) for the tray bolts.
  • Move any harness retainers out of the way using a trim clip removal tool.

Step 7: Remove the left engine mount fasteners

  • Use a ratchet with extensions and a universal swivel joint adapter as needed to reach the mount fasteners.
  • Loosen the mount-to-frame fasteners, then the mount-to-engine bracket fasteners using the correct metric sockets/wrenches.
  • Adjust engine height slightly with the floor jack to take pressure off the mount, then remove all fasteners.
  • Torque: Torque to OEM spec (varies by mount/fastener set)

Step 8: Remove and replace the left engine mount

  • Remove the old mount. Use a pry bar gently only if needed.
  • Install the new mount and hand-start all fasteners.
  • Use a ratchet to snug fasteners evenly.

Step 9: Final align, then torque fasteners

  • Slowly lower the engine with the floor jack until it sits naturally on both mounts.
  • With the engine resting (not lifted), use a torque wrench to tighten mount fasteners.
  • Torque: Torque all mount fasteners to OEM spec
  • Tip: tightened while lifted can cause vibration.

Step 10: Reinstall removed components

  • Reinstall the battery tray/battery if removed using a socket set.
  • Reconnect battery terminals using a 10mm socket: positive (+) first, negative (-) last.
  • Reinstall the air intake components using a 10mm socket and flathead screwdriver.

Step 11: Lower the truck

  • Use the floor jack to lift slightly, remove jack stands, then lower to the ground.

✅ After Repair

  • Start the engine and let it idle in Park. Listen for clunks and watch for excessive engine movement.
  • With your foot on the brake, lightly shift through R and D and back to P. Movement should be controlled, not jerky.
  • Take a short test drive and check for new vibrations.
  • Re-check that all removed intake/battery fasteners are tight using the socket set.

💰 DIY vs Shop Cost
