Parts for your 1991 Nissan Primera-Engine mount

1991 Nissan Primera (P10) Engine Mounts

Engine mounts are absolutely fitted to the 1991 Nissan Primera (P10). Technical sources including the Nissan Primera P10 Factory Service Manual (engine mounting section), the Nissan FAST electronic parts catalogue for P10 models (1990–1995), and mainstream parts catalogues list multiple engine mounting insulators and a torque rod/roll stopper for this vehicle across GA16, SR20 and diesel variants.

The engine mounts on a 1991 Primera do a deceptively big job: they hold the engine and transaxle in the right spot under the bonnet, soak up vibration, and control how the drivetrain twists under load. That means less buzz through the cabin, cleaner gear changes and fewer knocks when taking off or backing off. Some variants use hydraulic mounts to further tame vibration, while the torque rod (front/rear roll stop) keeps the engine from rocking when the throttle is opened.

Because these cars are now three decades old, mounts are a common wear item. There’s no fixed replacement interval, but smart servicing includes an inspection every service or 20,000 km. Look for:

• Shudder or excessive vibration at idle or in Drive
• Clunks on take-off, overrun or gear changes
• Visible cracks/tears in the rubber, or fluid seepage from a hydraulic mount
• Exhaust or shifter misalignment after bumps or hard acceleration

When replacement is due, using quality OE or reputable aftermarket mounts pays off in comfort and longevity. It’s common to replace the main side mount and the front/rear roll stops together if they’re aged, as a weak mount can quickly stress the others.

Fitment tips for a 1991 Primera:

• Safely support the engine/gearbox with a jack and timber block, never rely on a mount being removed.
• Loosen mount fasteners, settle the engine at ride height, then torque to factory spec from the P10 manual.
• Check torque rod bushes and the transmission-side mount while you’re there.
• After installation, verify clearance around the exhaust, radiator hoses and driveshafts.

Expect 1–2 hours labour per mount depending on access and corrosion. A wheel alignment isn’t typically required, but it’s wise to road test for NVH improvements and recheck torques after a few heat cycles. Sorted mounts make a P10 feel tight again—and protect CV joints, exhaust flex sections and shifter linkages from premature wear.

Popular questions about 1991 Nissan Primera engine mounts

How many engine mounts does a 1991 Primera have?
Most P10s use four mounting points: right-hand engine mount, left-hand/transmission mount, plus front and rear roll-stop (torque) mounts. Exact layout and part styles can vary slightly by engine (GA16, SR20 or diesel).

Are SR20 and GA16 engine mounts interchangeable?
Not reliably. Brackets and insulator specs often differ between engines and markets. Always match to the VIN/engine code and confirm part numbers in the Nissan FAST EPC or a trusted catalogue.

Should hydraulic mounts be replaced with solid or polyurethane types?
Stick with the mount type specified for the engine if comfort is a priority. Hydraulic mounts reduce idle vibration. Polyurethane and solid options can sharpen response but usually increase cabin NVH, which some daily drivers won’t love.
