Parts for your 2010 Nissan Pathfinder-Engine mount

2010 Nissan Pathfinder engine mount — purpose, checks and replacement tips

Engine mounts are absolutely fitted to the 2010 Nissan Pathfinder (R51). Technical sources including the Nissan R51 Factory Service Manual (FSM) — EM: Engine Mechanical, “Engine Mounting” — and the Nissan FAST parts catalogue list left and right engine insulator mounts and a separate transmission mount for both VQ40DE petrol and YD25 diesel variants. Aftermarket catalogues from recognised suppliers in Australia and New Zealand (e.g., Mackay and OEM-equivalent listings) also show direct-fit mounts for the 2010 model, confirming their use.

On this Pathfinder, the engine mounts support the weight of the engine, hold the driveline at the correct angle, and soak up vibration so the cabin stays quiet and comfortable. They also limit engine movement under acceleration and on rough roads, helping protect hoses, wiring and the exhaust from stress.

Most R51s use rubber-hydraulic “insulator” mounts on the left and right of the engine, with a separate mount at the transmission crossmember. Petrol and diesel layouts differ slightly, but the job they do is the same: isolate noise, vibration and harshness while keeping everything aligned.

• Common signs it’s time to replace: increased vibration at idle, a thump or clunk on gear changes, visible perishing or splitting of the rubber, or fluid seepage from a hydraulic mount.
• Inspection tip: check for excessive engine rock when the bonnet is up — have a helper briefly blip the throttle in Drive and Reverse with the foot brake on, noticeable lurching suggests a tired mount.

Engine mounts aren’t a scheduled replacement item, but they should be inspected at major services (every 40,000–60,000 km) or whenever driveline vibration or knocking appears. In harsh use — towing, off-roading, corrugations — expect faster wear.

Replacement is straightforward for a skilled home mechanic, but access can be tight. Support the engine with an engine support bar or a jack and timber under the sump, replace one side at a time, and always follow the FSM for safe lifting points, bolt order and torque specs. Avoid prying on alloy housings or the sump. If one side has failed, replacing both engine insulators together is smart practice to keep balance and longevity. Use quality OEM or reputable aftermarket mounts, cheap rubber can collapse early and bring the vibration back.

After fitting, recheck torque after a short shakedown drive, and keep an ear out for new vibrations that could indicate a loose fastener or misaligned bracket.

FAQs

How many engine mounts does a 2010 Nissan Pathfinder have?
Most R51 Pathfinders use two engine insulator mounts (left and right) plus a separate transmission mount. The exact bracket shapes differ between the VQ40DE petrol and YD25 diesel, but the count and function are similar. The Nissan FSM and parts catalogue identify all three.

What are the symptoms of bad engine mounts on a 2010 Pathfinder?
Owners typically notice more vibration at idle, a clunk on take-off or shift, and the engine rocking more than usual when blipping the throttle. Visual checks may show cracked or collapsed rubber, or fluid weeping from a hydraulic mount. Any of these signs warrant an inspection and likely replacement.

Is it safe to keep driving with a failed engine mount?
Short trips may be possible, but it’s not recommended. Excessive movement can stress hoses, wiring and the exhaust, and may worsen drivetrain alignment, leading to costly knock-on issues. It’s best to book the vehicle into a workshop promptly.
