Parts for your 2001 Nissan Serena-Engine mount

2001 Nissan Serena engine mount — what it does and how to look after it

Based on Nissan’s own C24 Serena Factory Service Manual (Engine Mechanical and “Engine Mounting” sections) and the Nissan FAST electronic parts catalogue, the 2001 Nissan Serena absolutely uses engine mounts. These references list the engine mount insulators and brackets and set‑out inspection and replacement procedures, so the engine mount is both relevant and fitted to this model.

The engine mount’s job on a 2001 Serena is to hold the engine and transaxle securely in the bay while soaking up vibration so the cabin stays calm. It also manages engine torque when taking off, keeps driveline angles happy, and helps protect hoses, wiring and the exhaust from strain. On the C24 Serena (QR20DE and other variants), the layout typically includes a right-hand engine mount, a left-hand transmission mount, and front and rear torque/roll mounts. Many are hydraulic (fluid-filled) to further smooth out idle and low‑speed shudder.

There’s no fixed replacement interval, but mounts are considered wear items. As part of routine servicing, a quick visual and functional check is smart: look for perished or cracked rubber, collapsed mounts, torn bonding, or oil leakage from hydraulic mounts. Under the bonnet, have someone blip the throttle in gear (with the handbrake on) and watch for excessive engine rock. Any clunks on take‑off, vibration at idle that wasn’t there before, or thumps on gear changes are classic flags.

• Common symptoms: harsh vibration at idle, knocking under load or when shifting, visible sag or contact between brackets, and fluid weeping from hydromounts.
• Service tips: inspect every 20,000–30,000 km or when chasing NVH complaints, check adjacent bits like the exhaust flex, hoses and driveshafts for strain if a mount looks tired.

When replacing, support the engine with a support bar or hoist, never a jack on the sump. Fit quality OE or OE‑equivalent rubber/hydraulic mounts—solid or stiff poly options can dial in extra vibration you won’t want in a family MPV. Tighten fasteners with the vehicle settled at normal ride height so the mount sits in a neutral position, and torque to spec. If one mount has failed and the rest are the same age, it’s often worth doing the opposing mount to keep NVH balanced. A quick road test after fitting should confirm smooth idle and clean take‑offs with no new noises.

Driving long‑term with a failed mount can stress the exhaust, CV joints and even crack brackets, so it’s best sorted promptly.

FAQs

How many engine mounts does a 2001 Nissan Serena have?
Most C24 Serenas run four: a right‑hand engine mount, a left‑hand trans mount, plus front and rear torque (roll) mounts. Driveline variants can differ slightly, but that four‑point setup is the norm according to Nissan service literature and parts catalogues.

What are the tell‑tale signs my Serena’s engine mount is worn?
Look for new vibrations at idle, a clunk when shifting from Park to Drive/Reverse, a thump on take‑off, or visible engine movement when someone feathers the throttle. Hydraulic mounts may show fluid stains, rubber-only mounts often crack or collapse.

How long does replacement take and what might it cost?
A single mount is commonly 1.5–3.0 hours depending on access and corrosion. In Australia and New Zealand, quality mounts typically land around $120–$350 per mount, with labour rates varying by workshop. If multiple mounts are tired, it’s often more efficient to do them together.
