Parts for your 2009 Nissan Pathfinder-Engine mount

2009 Nissan Pathfinder engine-mount

Yes, the 2009 Nissan Pathfinder (R51) absolutely uses engine mounts. This is confirmed by Nissan’s R51 Factory Service Manual (EM – Engine Mechanical, Engine Mounting section), which details the mount locations and removal/installation procedures for both VQ40DE petrol and YD25 diesel variants. Nissan’s electronic parts catalogues (FAST) and dealer parts listings also show right- and left-hand engine mounting insulators and related brackets for the 2009 model year.

On this Pathfinder, the engine mounts secure the engine to the chassis while isolating vibration and harshness from the cabin. They keep the driveline aligned under load, control torque reaction on take-off, and protect surrounding components from shock. Some variants use hydraulic (fluid-filled) mounts to further smooth out idle vibration, all are designed to balance comfort with the towing and off-road demands the R51 often sees in Australia and New Zealand.

As part of routine servicing, it’s smart to inspect the engine mounts every 20,000–30,000 kilometres or whenever driveline vibration or clunks show up. Look for perished rubber, collapsed heights, fluid seepage from hydraulic mounts, or excessive engine movement when shifting between Reverse and Drive. Towing, corrugations, and beach work can accelerate wear, so vehicles that work hard deserve closer attention.

• Common signs they’re tired: noticeable vibration at idle in gear, a thud on take-off or over bumps, shudder when loading the engine, or exhaust/hoses appearing strained due to engine sag.
• Good practice: replace mounts in pairs (left and right) to maintain balance, also assess the transmission mount at the same time.

Replacement is straightforward for a trained tech but can be fiddly on the driveway. Support the engine with a hoist bar or a jack and timber under a strong point (never the sump), relieve the load on the mount, then swap one side at a time. Align everything carefully, start all fasteners by hand, and final-tighten to the Nissan workshop specifications with the vehicle at normal ride height so the rubber sits neutral. Refit any heat shields and check for adequate clearance to the fan shroud, exhaust, and steering gear. After replacement, a quick road test for NVH and a visual recheck is worthwhile.

There’s no fixed replacement interval, many last well past 150,000 km. If the Pathfinder tows a boat, carries heavy gear, or spends time off-road, earlier replacement can restore refinement and protect other components.

How long do engine mounts last on a 2009 Pathfinder?
With moderate use, many owners see 120,000–200,000 kilometres before noticeable symptoms. High heat, towing, corrugations, and diesel torque loads can shorten that. Regular inspections during servicing help catch issues early.

Can they be replaced at home, or is a workshop best?
A confident DIYer with stands, a solid jack, and patience can do it, but access is tight and safe engine support is critical. Most owners prefer a workshop with an engine support bar and hoist to ensure proper alignment and torqueing.

Are diesel and petrol mounts the same?
No. Mounts differ by engine and sometimes by transmission and trim. The durometer and bracket geometry vary, so they’re not interchangeable. Always order by VIN to get the correct left/right mount set.
