Parts for your 2008 Isuzu D-max-Engine mount

2008 Isuzu D‑Max Engine Mounts

Engine mounts are absolutely fitted to the 2008 Isuzu D‑Max and are relevant to its servicing. This is confirmed by the Isuzu D‑Max/KB (RA series, 2007–2012) workshop manual and the Isuzu electronic parts catalogue, which list left- and right-hand “engine mounting insulator” assemblies for the 3.0‑litre 4JJ1 diesel. Equivalent listings appear in Holden RA Rodeo technical parts references, given the shared platform.

The engine mounts on a 2008 D‑Max do the heavy lifting of holding the 4JJ1 diesel in place while soaking up vibration and torque twist. By isolating the cabin from engine shake, they help keep noise and harshness down, stop the fan and pulleys from going out of line, and protect components like the exhaust, hoses and intercooler plumbing. The setup typically uses two primary side mounts on the engine with a separate transmission mount at the rear, working together to keep everything aligned under load, on corrugations, and during towing.

As part of regular servicing, it’s smart to inspect the mounts for cracking, splitting or oil-soaked rubber, loose hardware, and any signs the engine sits lower on one side. Diesel leaks and engine oil can degrade rubber, so keeping on top of leaks pays off. Many owners in Australia and New Zealand find mounts last well past 150,000 km, but rough roads, constant towing or heavy accessories can shorten that. When one mount is shot, replacing both sides as a pair helps restore balance and longevity.

Replacement is a straightforward job for a workshop with an engine support bar or a jack and timber block under the sump. Always support the engine before undoing mount hardware, align the new insulator without forcing it, and torque fasteners only after the engine is settled at ride height. After installation, recheck clearances around the fan shroud, exhaust and intercooler pipes, then road‑test for idle smoothness and take‑off shudder.

• Common signs of worn mounts on a D‑Max:
  • Extra vibration at idle or when selecting Drive/Reverse
  • Clunk or thud on take‑off or over bumps
  • Visible sagging or separated rubber on the mount
  • Exhaust strain or contact noises under load

For touring or fleet use, add a quick visual check of the mounts to every service and after long corrugated runs. Quality OEM or reputable aftermarket insulators generally deliver the best result for durability and cabin refinement.

FAQs

Does the 2008 Isuzu D‑Max have engine mounts, and how many?
Yes. The RA‑series D‑Max uses two primary engine mounts (left and right) plus a separate transmission mount at the rear. This layout is shown in the Isuzu workshop manual and parts catalogue for the 4JJ1 diesel models.

What are the tell‑tale signs an engine mount is failing on a 2008 D‑Max?
Look for excess vibration at idle, a thud when shifting into gear, the engine sitting off‑centre, or rubber that’s cracked, oil‑soaked or separated. You might also hear exhaust contact or feel more driveline shudder on take‑off.

When should engine mounts be replaced on a D‑Max, and can it be a DIY job?
There’s no set kilometre interval, inspect them at each service and replace when worn. Many last 150,000–250,000 km depending on loads and road conditions. Skilled DIYers can tackle the job with proper engine support and safety gear, but most owners prefer a workshop due to the need to safely support the engine and correctly align and torque the mounts.
