Parts for your 1985 Suzuki Jimny-Engine mount

1985 Suzuki Jimny (SJ410/SJ413) engine mount — purpose, care, and when to replace

Engine mounts are absolutely fitted to the 1985 Suzuki Jimny (sold in Aus/NZ as the Sierra). Technical references including the Suzuki SJ410/SJ413 Factory Service Manual (Engine/Engine Mounting section), the Suzuki Electronic Parts Catalogue for SJ models (listing “Insulator, engine mounting” for left and right), and Gregory’s and Haynes workshop manuals all document the left and right rubber engine mounting insulators and a separate transmission mount. Whether running the F10A 1.0-litre or the G13A 1.3-litre, the ’85 Jimny/Sierra relies on these mounts to secure the engine to the ladder frame while controlling vibration.

Their job is simple but critical: a pair of rubber-bonded insulators support the engine, isolate harshness, and keep the driveline aligned. In a lightweight 4x4 that flexes its chassis off-road, good mounts stop the engine shifting about, reduce buzz through the cabin, and help protect the exhaust, radiator hoses and shifter linkages. When the rubber perishes, tears, or oil-soaks, the engine can sit low or cocked on one side, which leads to shudders on take-off, clunks when changing gears, and more vibration at idle. It can even let the fan kiss the shroud on big bumps.

As part of regular servicing, it’s worth a look under the bonnet. Check for cracked or separated rubber, collapsed height, shiny witness marks from contact, and any oil contamination from rocker cover or front seal leaks. Typical tell-tales include:

• Extra vibration at idle or through the seats
• Gear lever moving more than usual on and off the throttle
• Knock or thud when selecting drive or during clutch take-up
• Fan or pulley close to the shroud or guard

Replacement is straightforward with basic spanners, axle stands and a jack with a timber block under the sump. Support the engine, crack the through-bolts, remove the mount-to-bracket nuts, lift the engine a tad, and swap the mounts. Fit them as a pair, loosely assemble, then settle the engine and torque to the factory specs from the FSM. After a short shakedown (100–200 kilometres), re-check fasteners. While you’re there, inspect the transmission mount too. OE-style rubber mounts keep the Jimny comfy, harder polyurethane options suit rough work but can add a bit of NVH. Keep oil leaks in check so the new mounts last.

FAQs

How many engine mounts does a 1985 Suzuki Jimny/Sierra have?
It uses two engine mounting insulators (left and right) and a separate transmission/gearbox mount. All three work together to support and align the powertrain.

What are the common signs the engine mounts need replacing?
Expect more vibration at idle, a clunk when shifting or taking off, extra movement of the gear lever, and sometimes fan-to-shroud contact. Visual checks may show torn or oil-soaked rubber or a sagging mount.

Should the mounts be replaced as a pair and how often?
Yes, replace the left and right engine mounts as a pair to keep the engine sitting level. There’s no fixed interval, inspect at each service. Off-road use, oil leaks, and age can shorten their life.
