🔧 Altima - Engine Mounts Replacement

Your Altima uses multiple engine/transmission mounts, and the replacement procedure is very different depending on which mount(s) you’re doing (right/passenger side, left/driver side, lower “torque” mount, or rear mount). The correct steps also depend on whether you’re supporting the engine from above or from below.

Difficulty Level: Intermediate | Estimated Time: 1.0–6.0 hours (depends which mount)

⚠️ Safety & Precautions

• ⚠️ Never remove a mount without supporting the engine/transmission; it can drop and damage hoses/wiring.
• ⚠️ Support the car with jack stands on the pinch welds/approved lift points; never rely on a floor jack alone.
• ⚠️ If you support the engine from below, use a wide wood block on the jack pad to spread the load and avoid denting the oil pan.
• ⚠️ Keep hands clear when slightly raising/lowering the engine to align bolt holes.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels.
• Open the hood and remove any loose items so nothing falls into the engine bay.
• Plan how you’ll support the engine: a floor jack with a wood block under the engine is the common DIY method.

I need 2 quick details to give you the exact, mount-specific steps and torque specs:

• Which mount(s) are you replacing on your Altima: right (passenger upper), left (driver/trans mount), lower torque mount, or rear mount?
• Do you have a floor jack + jack stands available to support the engine safely?

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Identify the mount position(s) you’re working on

• Use a flashlight and look for the mount location: right side (near passenger-side strut tower), left side (near driver-side frame rail/trans), and lower mounts under the vehicle.
• Use a flashlight to check for cracked rubber, separated rubber, or leaking fluid (some mounts are fluid-filled).
• Take a photo before removing anything.

Step 2: Do a safe “support check” before any bolts come out

• Position the floor jack (rated 3-ton minimum) under the engine with a wood block (2x6 in. minimum) on the jack pad.
• Raise the jack just until it contacts and lightly supports the engine (do not lift the car).
• Confirm nothing is being crushed or pulled tight (hoses, wiring).

Step 3: Stop here and confirm your mount choice

• Reply with which mount(s) you’re replacing, and I’ll give you the exact removal order, access panels to remove, and the correct Torque to XX Nm (YY ft-lbs) specs for your Altima.

✅ After Repair

• Start the engine and check for abnormal vibration at idle (in Park and in Drive with the brake held).

• Recheck all visible fasteners after the test drive for anything that loosened.
