Hyundai iLoad & iMax Replacement Engine Guide
When a Hyundai iLoad or iMax loses its engine, someone usually loses income with it. These vans work hard — couriers, tradies, shuttle operators — and the priority is almost always the same: get a reliable engine in and the van back on the road with minimum downtime. This guide covers both iLoad engines, what a brand-new replacement costs, and how to keep the off-road time short.
The Two iLoad/iMax Engines
- 2.5 CRDi turbo diesel (D4CB) — the majority of the fleet. A strong engine when serviced, but hard commercial kilometres expose injector seal problems, turbo wear and, on neglected examples, bottom-end damage. Brand-new D4CB engines here.
- 2.4 petrol (G4KG) — the less common petrol option, typically on earlier vans and some iMax people-movers. Brand-new G4KG engines here.
Note that the D4CB changed over its life — different emissions equipment and injection variants across years — so year and VIN matter when ordering. We confirm the exact variant against your VIN before dispatch under our fitment guarantee.
Why Brand New Makes Sense on a Working Van
For a commercial vehicle, the engine maths is really downtime maths. A brand-new long engine arrives tested, with zero wear history, and goes straight in — no waiting on machining, no surprises mid-job. Every Engine Zone engine is newly manufactured to OEM fitment spec, hot-and-cold tested before dispatch, fitted with a heat tab, and covered by our 12-month/50,000 km parts warranty. On a van that earns its keep daily, predictable is profitable.
What the Job Involves
Our iLoad engines are supplied as long engines. Your workshop transfers the turbo, injection system, manifolds and accessories from the original engine — and on a high-kilometre van it is worth budgeting for injectors, engine mounts and the water pump while everything is accessible. The full sequence from diagnosis to road-ready is covered in our engine replacement process guide.
Cost, Freight and Downtime
- Engine: brand-new D4CB or G4KG long engines typically sit in the $4,000–$7,500 bracket depending on variant.
- Labour: $1,500–$4,000 at a workshop, depending on what else is replaced during the swap.
- Freight: free Australia-wide; metro deliveries usually land in 1–3 business days (see how crate engine delivery works).
- Downtime: most workshops turn an iLoad engine swap around in 2–5 working days once the engine arrives.
After installation, follow our run-in guide for the first 1,500 km — a gentle first week protects the investment for the next several hundred thousand kilometres.
