🔧 Tucson - Engine Mount Replacement

Replacing the engine mounts on your Tucson involves safely supporting the engine, removing the worn mount, and installing the new mount without stressing the drivetrain. On the 1.6L turbo FWD Tucson, the upper engine mount is the most beginner-friendly; the lower torque mount is moderate; the transmission-side mount is more involved.

Difficulty Level: Intermediate | Estimated Time: 1.5-3 hours per mount

⚠️ Safety & Precautions

• ⚠️ Support the engine before removing any mount. Never let the engine hang by hoses, wiring, exhaust, or other mounts.
• ⚠️ Use jack stands on solid ground. Never work under a vehicle supported only by a floor jack.
• ⚠️ Disconnect the negative battery cable before working around the engine mount area.
• ⚠️ Do not place the jack directly on the aluminum oil pan without a wide wood block.
• ⚠️ Remove and install one mount at a time to keep the engine and transmission aligned.
• ⚠️ Some bolts are torque-to-yield on Hyundai applications. Replace mount bolts if the replacement mount instructions require it.

📋 Before You Begin

• Park your Tucson on level ground.
• Shift to Park and set the parking brake.
• Place wheel chocks behind the rear wheels.
• Let the engine cool completely before working near the turbocharger and exhaust.
• Use a 10mm socket and ratchet handle to disconnect the negative battery cable.
• Use a paint marker to mark the original mount position before removal. This helps keep alignment close during installation.
• A torque wrench is a tool that tightens bolts to a measured tightness so parts are not left loose or overtightened.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and Secure the Vehicle

• Use a floor jack rated 2-ton minimum to lift the front of your Tucson at the front center jacking point.
• Place jack stands rated 2-ton minimum under the approved front pinch weld or front support points.
• Lower the vehicle gently onto the jack stands.
• Shake the vehicle lightly by hand to confirm it is stable.
• Tip: Stability matters more than speed.

Step 2: Remove the Lower Splash Shield

• Use a 10mm socket to remove the splash shield bolts.
• Use a trim clip removal tool to remove plastic retaining clips.
• Use a flat-blade screwdriver only if a clip center pin needs gentle lifting.
• Set the splash shield and hardware aside in order.

Step 3: Support the Engine

• Place a wood block 12-inch x 12-inch minimum on the saddle of the floor jack.
• Position the jack and wood block under the strongest flat area near the engine oil pan edge, not on a drain plug or thin stamped area.
• Raise the jack slowly until the wood block just contacts the engine.
• Lift only enough to support the engine weight. Do not raise the vehicle off the jack stands.

Step 4: Inspect and Choose the Mount Being Replaced

• Use a flashlight to inspect the right upper engine mount near the passenger-side inner fender.
• Use a flashlight to inspect the lower torque mount under the engine/transmission area.
• Use a flashlight to inspect the left transmission mount on the driver-side transmission area.
• Replace only one mount at a time.

Step 5A: Remove the Right Upper Engine Mount

• Use a 10mm socket to remove any intake duct bracket or harness bracket blocking access.
• Use a paint marker to mark the mount position on the body and engine bracket.
• Use a 17mm socket, 6-inch extension, and ratchet handle to loosen the mount-to-body bolts.
• Use a 17mm socket and breaker bar 1/2-inch drive to loosen the mount-to-engine bracket nut or bolt.
• Raise or lower the engine very slightly with the floor jack rated 2-ton minimum until the bolts slide out without binding.
• Remove the mount by hand.

Step 6A: Install the Right Upper Engine Mount

• Place the new right upper engine mount into position by hand.
• Start all bolts and nuts by hand first to avoid cross-threading.
• Use a 17mm socket and ratchet handle to snug the fasteners lightly.
• Align the mount to your paint marker marks.
• Use a torque wrench 10-150 ft-lb range and 17mm socket to tighten the mount-to-body bolts to Torque to 60-75 Nm (44-55 ft-lbs).
• Use a torque wrench 10-150 ft-lb range and 17mm socket to tighten the mount-to-engine bracket fastener to Torque to 75-95 Nm (55-70 ft-lbs).

Step 5B: Remove the Lower Engine Torque Mount

• Work from underneath the vehicle with safety glasses on.
• Use a paint marker to mark the lower torque mount position.
• Use a 17mm socket, 12-inch extension, and breaker bar 1/2-inch drive to loosen the large through-bolt.
• Use a 17mm socket and ratchet handle to remove the remaining bracket bolt or bolts.
• Use the floor jack rated 2-ton minimum to slightly adjust engine height if the bolt is tight from engine weight.
• Remove the lower torque mount by hand.

Step 6B: Install the Lower Engine Torque Mount

• Position the new lower engine torque mount by hand.
• Start all bolts by hand first.
• Use a 17mm socket and ratchet handle to snug the fasteners.
• Use a torque wrench 10-150 ft-lb range, 17mm socket, and 12-inch extension to tighten the large through-bolt to Torque to 90-110 Nm (66-81 ft-lbs).
• Use a torque wrench 10-150 ft-lb range and 17mm socket to tighten the bracket bolts to Torque to 65-85 Nm (48-63 ft-lbs).

Step 5C: Remove the Left Transmission Mount

• Support the transmission side with the floor jack rated 2-ton minimum and wood block 12-inch x 12-inch minimum.
• Use a 10mm socket and 12mm socket to remove any battery tray, air duct, or bracket fasteners blocking access.
• Use a paint marker to mark the transmission mount position.
• Use a 17mm socket, 19mm socket, 6-inch extension, and breaker bar 1/2-inch drive to loosen the mount fasteners.
• Use a universal joint socket adapter if bolt access is angled.
• Raise or lower the transmission slightly with the floor jack until the fasteners slide out cleanly.
• Remove the mount by hand.

Step 6C: Install the Left Transmission Mount

• Place the new left transmission mount into position by hand.
• Start every fastener by hand before tightening.
• Use a 17mm socket or 19mm socket and ratchet handle to snug the fasteners.
• Align the mount with your paint marker marks.
• Use a torque wrench 10-150 ft-lb range and correct socket to tighten body-side mount bolts to Torque to 60-75 Nm (44-55 ft-lbs).
• Use a torque wrench 10-150 ft-lb range and correct socket to tighten transmission-side fasteners to Torque to 75-95 Nm (55-70 ft-lbs).

Step 7: Settle the Engine and Recheck Fasteners

• Make sure the mount sits naturally and is not twisted.
• Use the torque wrench 10-150 ft-lb range and correct socket to recheck each fastener torque.
• Confirm no wiring, hoses, or brackets are pinched under the mount.

Step 8: Reinstall Brackets and Splash Shield

• ✅ Listen for clunks, rattles, or new vibration.
• ✅ Take a short, gentle road test.
• ✅ Recheck the repaired mount area for loose fasteners after the road test.
• ✅ If idle vibration is worse, the mount may be misaligned or another mount may also be worn.
