Parts for your 2004 Nissan Primera-Engine mount

2004 Nissan Primera Engine Mounts

Based on technical sources, engine mounts are absolutely fitted and relevant on the 2004 Nissan Primera (P12). The Nissan Primera P12 Series Factory Service Manual (2002–2006), Section EM “Engine Mounting,” details the mount layout and procedures. The Nissan FAST electronic parts catalogue for 2004 Primera variants (QG18DE, QR20DE petrol and YD22DDTi diesel) lists a right-hand engine mounting insulator, a left-hand transmission mount, and front/rear torque rod mounts. These references confirm the vehicle uses multiple mounts to secure and control the powertrain.

The 2004 Primera’s engine mounts do more than just hold the engine in place. They isolate cabin vibration, align the engine and gearbox under the bonnet, and control powertrain movement under acceleration, braking and gear changes. Many P12s use a fluid-filled (hydraulic) right-hand mount paired with a left trans mount and two torque mounts (front and rear) that limit twist. When they’re healthy, the car feels smooth at idle and composed on take-off. When they’re tired, shakes, clonks and harshness creep in.

As part of routine servicing in Australia and New Zealand, it’s smart to have the mounts visually checked and gently loaded with a pry bar while the engine is safely supported. A quick look every service, and a more careful inspection at major intervals, helps catch early wear before it rattles the whole cabin.

• Common signs of worn mounts: extra vibration at idle, a thud on start-up or shift, engine rocking on take-off, exhaust or driveshaft strain, split rubber or fluid seepage from a hydraulic mount.
• If one mount has failed, the others often aren’t far behind—consider them as a set.

Replacement is straightforward for a trained tech: support the engine with a bar or jack and wood block, remove the mount’s bolts, swap the unit, then torque to the service manual specs with the drivetrain at normal ride height. Always follow the Primera P12 torque settings, replace any single‑use (stretch) bolts if specified, and recheck for clearance around hoses and the exhaust. Quality OE or OEM‑equivalent mounts last longer and keep NVH low. After fitting, a short road test should confirm smooth idle, clean shifts and no knock on lift-off.

• Tip: If vibration persists after new mounts, check the torque rod bushes, lower crossmember fasteners, and idle quality—poor idle can mimic mount issues.

FAQs

How many engine mounts does a 2004 Nissan Primera have?
Most P12 models run four: a right-hand engine mount (insulator), a left-hand transmission mount, and front and rear torque (roll) mounts. Exact design can vary slightly by engine (QG18DE, QR20DE, YD22DDTi), but the four-point layout is the norm.

What are the signs my Primera’s engine mount is worn?
Expect more vibration through the steering wheel and seats at idle, a clunk when shifting into Drive or taking off, and a shudder on lift-off or over bumps. Visual clues include cracked rubber or fluid leaking from a hydraulic mount.

Is it safe to keep driving with a bad engine mount?
Short distances might be manageable, but it’s not ideal. A failed mount can stress the exhaust, hoses and driveshafts, and it can make gear changes harsh. Sorting it sooner protects the rest of the car and brings back that smooth, quiet feel.
