Parts for your 2004 Mitsubishi Pajero-Engine mount

2004 Mitsubishi Pajero engine-mount: what it does, when it wears, and how to sort it

The 2004 Mitsubishi Pajero is fitted with engine-mounts. Technical references including the Mitsubishi Motors Workshop Manual for the NM–NP Pajero/Montero (2000–2006 series) and the Mitsubishi ASA electronic parts catalogue list multiple engine mounting insulators and brackets for both petrol and 3.2 Di‑D diesel variants, along with a torque/roll limiter. So an engine-mount is absolutely relevant to this model.

On this Pajero, the engine-mounts support the engine’s weight, keep the driveline aligned, and soak up vibration so the cabin stays calm. Under throttle, mounts control engine rock so there’s less thump through the chassis and fewer stresses on hoses, exhaust, and the transfer case. Many variants use hydraulic (fluid‑filled) mounts for better vibration isolation at idle.

As part of regular servicing, it’s smart to inspect the engine-mounts whenever the bonnet’s up. Look for collapsed rubber, torn bonding, separated brackets, or fluid seepage from hydraulic mounts. A pry bar check (light pressure only) can reveal excessive movement. Any oil contamination from leaks will shorten mount life and should be sorted promptly.

• Common symptoms of worn engine-mounts on a Pajero:
  • Rougher idle or a buzz through the steering wheel
  • Clunk on take‑off, gear changes, or over corrugations
  • Excessive engine movement when shifting from Park to Drive
  • Exhaust contact or shudder under load

Replacement is straightforward for a trained tech but space can be tight. The engine must be safely supported (never jack on the sump), the mount-to-block and mount-to-crossmember fasteners removed, and the new mount installed with the engine settled on its weight before final torque. Pair replacement (left and right) is often advised to keep balance and ride quality consistent. It also pays to check the transmission mount and any torque rod at the same time.

Quality matters: choose OEM or reputable aftermarket mounts matched to engine type (diesel vs petrol) and build code. Hard off‑road use, towing, and heat can age mounts sooner, highway cruisers tend to see longer service life. With fresh mounts, the NP Pajero feels tighter, shifts cleaner, and is nicer to live with on Kiwi and Aussie roads alike.

FAQs

How long do engine-mounts typically last on a 2004 Pajero?
In normal mixed driving they often last 150,000–250,000 kilometres. Heavy towing, corrugations, and oil leaks can shorten that. Condition is more important than mileage—if there’s vibration at idle or clunks on take‑off, it’s time for an inspection.

Is it safe to keep driving with a failed engine-mount?
It’ll usually still drive, but it’s not ideal. Excess movement can stress the exhaust, cooling hoses, and driveline, and may create harsher gear changes. Continued use risks extra repair costs, so owners generally organise replacement sooner rather than later.

Are diesel and petrol Pajero engine-mounts interchangeable?
Generally no. Mount design and stiffness vary by engine and body series. The correct part is chosen by VIN/build code to handle the specific weight and torque characteristics of the engine fitted.
