🔧 Altima - Engine Mount Replacement

Replacing engine mounts on your Altima means safely supporting the engine, unbolting the worn mount(s), and installing the new ones in the correct order so the drivetrain sits square and doesn’t bind or vibrate. The exact steps and torque specs change depending on which mount you’re replacing (right/passenger, left/driver transmission mount, front torque mount, rear torque mount).

Difficulty Level: Intermediate | Estimated Time: 2-5 hours (depends how many mounts)

⚠️ Safety & Precautions

• ⚠️ Support the engine before removing any mount; an unsupported engine can drop suddenly.
• ⚠️ Never get under the car supported only by a floor jack—use jack stands.
• ⚠️ Use a wood block between jack and oil pan; it spreads the load to avoid pan damage.
• ⚠️ Keep hands clear between the mount and brackets while raising/lowering the engine.
• ⚠️ Battery disconnect is recommended if you’ll be working near the starter/positive cable area: 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 loose items from the engine bay.
• If you’ll be near battery/starter wiring: use a 10mm socket to disconnect the negative battery terminal.
• Spray visible mount fasteners with penetrating oil and wait 10 minutes.
• Tip: Replacing mounts one-at-a-time keeps alignment easier.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Answer these 2 quick questions (so I give the exact mount steps + correct torque specs)

• Which mount(s) are you replacing: right engine mount, left transmission mount, front torque mount, rear torque mount, or all?
• Do you have a torque wrench available?

Step 2: Safely raise and support the car

• Place wheel chocks behind the rear tires.
• Use a floor jack at the front center jacking point to lift the front.
• Set the car down onto jack stands at the front pinch welds or approved support points.

Step 3: Support the engine (this is the critical part)

• Slide the floor jack under the engine oil pan area.
• Place the wood block on the jack pad, then gently jack up until the wood contacts the oil pan.
• Raise the jack just enough to take the weight off the mounts (you’ll usually see the mount “relax”).
• Tip: Don’t lift the engine high—just support it.

Step 4: Identify the mount you’re doing first

• Use a flashlight (phone light is fine) and locate:
• Right mount: passenger side, up high near the timing cover area.
• Left mount: driver side on top of the transmission.
• Front/rear torque mounts: lower mounts that control rocking.
• Use a paint marker to mark the mount/bracket position before loosening bolts.

Step 5: Stop here before loosening mount bolts

• Different mounts use different bolt sizes and different torque specs.
• Reply with your answers from Step 1 and I’ll give you the exact, mount-specific removal/install sequence and the correct torques for your Altima.

✅ After Repair

• Double-check every mount fastener is tightened and the engine sits level.
• Start the engine and let it idle; watch for excessive movement while you lightly blip the throttle.
• Test drive and listen for clunks on acceleration/deceleration.
• Recheck mount fasteners after a short drive.
