Parts for your 2020 Nissan Serena-Engine mount

2020 Nissan Serena engine-mount: what it does, when to replace it, and how to look after it

Engine mounts are absolutely fitted to the 2020 Nissan Serena. Factory technical documentation confirms this: the Nissan Electronic Service Manual (ESM) for the C27-series Serena (2016–2020) includes an Engine Mounting section showing right- and left-hand engine mounting insulators and a rear torque rod for MR20DD petrol and e-POWER HFC27 variants. Nissan’s FAST electronic parts catalogue lists these under Group 112 “Engine Mounting”, and genuine/aftermarket catalogues for the C27 Serena carry multiple mount insulators and torque rod assemblies. So, engine-mount is relevant for the 2020 Nissan Serena, whether it’s the conventional 2.0-litre S-HYBRID or the e-POWER model.

On this model, the engine-mounts are rubber (often hydraulic) insulators that hold the engine and transaxle steady while soaking up vibration. In day-to-day driving they keep the cabin calm at idle, stop shudders on take-off, and prevent the engine rocking about under load. The rear mount (torque rod) controls fore–aft movement when accelerating and backing off, while the side mounts carry the weight and quell vibration. On e-POWER variants, the mounts also isolate the generator engine and electric drive unit from the body to keep things smooth and quiet.

There isn’t a fixed replacement interval, but they’re wear items. Expect life anywhere from 100,000 to 200,000 km depending on driving, heat, and oil exposure. During regular servicing of a 2020 Nissan Serena engine-mount setup, a good workshop will visually check for perished rubber, cracks, collapsed mount height, and fluid seepage from hydraulic mounts. They’ll also note symptoms like harsh vibration at idle in Drive, clunks on gear changes, or a thud when getting on and off the throttle—classic signs a mount is tired.

If replacement’s needed, doing one mount can reveal others are on the way out, so it’s smart to assess the full set. Quality matters: go genuine or reputable OEM-equivalent. The engine must be safely supported with a crossbar support or jack and block, and mounts should be tightened at normal ride height to avoid preload. Torque specs are model-specific and should be followed from the ESM, some fasteners are torque-to-yield and shouldn’t be reused. After fitment, many techs do a quick road test and idle evaluation to be sure NVH is back to normal. Keeping oil and coolant leaks sorted will also help mounts last longer, as rubber and hydraulic units don’t love contamination.

• Watch for: increased cabin vibration, knocking on take-off, or visible sag in a mount.
• Service tip: inspect mounts each service, replace in pairs or as a set if multiple are marginal.
• Driving tip: avoid harsh launches and wheel hop—both shorten mount life.

Popular questions about 2020 Nissan Serena engine-mount

How can someone tell if their 2020 Serena needs new engine-mounts?
A rougher-than-usual idle in Drive, a clunk when shifting between Reverse and Drive, or a thud when accelerating or lifting off are strong clues. Under the bonnet, cracked rubber, leaking fluid from a hydraulic mount, or the engine sitting lower on one side also point to a failing mount.

Because other faults (misfires, worn driveline bushes) can feel similar, a workshop should confirm with a visual inspection and a controlled power-brake test while the engine is safely supported.

Do e-POWER Serenas use different mounts from the 2.0 S-HYBRID?
Yes, layouts and part numbers vary. Both have side mounts and a rear torque rod, but the e-POWER’s arrangement is tuned for its generator engine and electric drive. Always use mounts specified for the exact VIN and powertrain.

Can a home mechanic replace Serena engine-mounts?
It’s doable for experienced DIYers with proper support gear, but access can be tight and torque specs are critical. The engine must be supported correctly to avoid stressing hoses and wiring. Most owners are better off having a qualified technician handle it and road-test for NVH afterwards.
