About this engine
For a tradesperson or shuttle operator, a Hyundai iLoad or iMax that will not run is a business problem, not just a car problem. Every day off the road costs money, which changes the maths on repairs: the fastest reliable route back to work usually beats the cheapest one. This listing is a brand-new G4KG 2.4-litre petrol long engine to suit the Hyundai iLoad van and iMax people mover, built for owners who need the vehicle earning again with no doubts about what is under the floor.
The engine is new throughout, built to OEM fitment specification and hot and cold tested before dispatch. Freight anywhere in Australia is included, parts are warranted for 12 months or 50,000 km (whichever comes first), and a free VIN check before purchase confirms fitment for your exact vehicle. The team answers on 1300 200 320.
The G4KG 2.4 MPI: background and what wears
The G4KG is the workhorse of the Theta II family, Hyundai and Kia's widely used four-cylinder petrol platform. Where the G4KJ brought direct injection to passenger cars and the G4KH chased performance with a turbocharger, the G4KG stayed deliberately simple: a 2.4-litre engine with multi-point fuel injection, suited to commercial applications where ease of service and tolerance of hard use matter more than headline outputs.
Simplicity has practical benefits in a van. Multi-point injection sprays fuel onto the back of the intake valves, which keeps them washed clean, so the intake carbon build-up associated with GDI engines is far less of a factor here. The architecture is shared with the rest of the family: aluminium block and head, twin overhead camshafts, sixteen valves and a timing chain, meaning no belt replacement ever enters the service schedule.
Commercial life is still hard on engines. iLoad and iMax engines idle in traffic, haul at maximum load and often miss services because the vehicle cannot be spared, and while the connecting-rod bearing campaigns documented for the Theta II family overseas centred on other variants, hard use and stretched servicing are exactly the conditions that wear any engine's bottom end early. When a G4KG starts knocking, the commercial calculation is blunt: a rebuild means unknown downtime and an uncertain result, while a new long engine means a scheduled changeover and a known outcome, backed by a written warranty. This one is also built stronger than the original where it counts: OEM fitment specification outside, upgraded internals inside, with higher-grade connecting rods, crankshaft, bearings and other reinforced parts in place of the standard-specification components.
Fitment for Hyundai iLoad and iMax
This long engine suits Hyundai iLoad vans and iMax people movers originally fitted with the G4KG 2.4-litre petrol engine. Both models were also sold in large numbers with diesel power, so the fuel type and engine code need confirming before an engine is ordered, not after. We handle that with a free VIN compatibility check on every sale, and it costs you nothing beyond a phone call or an email.
Fleet buyers and workshops replacing engines for customers can send several VINs at once; each vehicle is confirmed individually against this engine. The 17-character number is on the registration certificate, the build plate and the windscreen plate. Phone it through on 1300 200 320 or email it, and we will verify the match before invoicing. Getting this step right protects your downtime planning, because the wrong engine arriving is a week lost, not an hour.
The changeover reuses your existing external hardware: intake and exhaust manifolds, injectors, throttle body, alternator, air conditioning compressor, starter, mounts and wiring. On a high-kilometre commercial vehicle, the smart money renews the water pump, thermostat, hoses, belts and engine mounts during the swap, and has the radiator flow-tested or replaced if there is any doubt about it. Cooling-system condition decides how long the new engine lasts, and vans loaded to the roof in summer traffic give it no margin at all. Any qualified mechanic or fleet workshop can complete the installation with standard equipment.
Crate contents and the replacement process
The crate contains a complete new G4KG long engine: assembled block with new crankshaft, bearings, pistons, rings and connecting rods, and an assembled cylinder head with new camshafts and valve components, all built to OEM specification. It is not a recondition; every part is new. Each engine is hot and cold tested after assembly, confirming oil pressure, compression and running condition before release.
Manifolds, injection components and accessories are excluded because your vehicle's own parts transfer across. A heat tab is fitted to every engine during the build. It records overheating permanently, and overheating damage is not covered by warranty, a point that matters for working vans where a blocked radiator or a failing fan can cook a new engine in a single hot afternoon.
Warranty covers parts for 12 months or 50,000 km, whichever comes first, with installation by a qualified mechanic required. Freight is free Australia-wide, direct to your workshop or depot. For a business, the sequence is plannable: confirm the VIN, order, book the vehicle in around the delivery, complete the changeover with cooling-system work included, then return the vehicle to service with an early oil change scheduled. Our team takes calls on 1300 200 320 if your workshop wants anything clarified before the job starts, which is usually quicker than working it out mid-job.
Frequently asked questions
Common questions about this engine. Have a different question? Call us on 1300 200 320.
Does this G4KG engine suit both the iLoad and the iMax?
Yes, it suits Hyundai iLoad vans and iMax people movers that were factory-fitted with the G4KG 2.4-litre petrol engine. Diesel versions of both models use a different engine entirely, so we confirm your vehicle's build by VIN, free, before any order is finalised.
What is a long engine in practical terms?
It is the engine's core, fully assembled: block, crank, pistons, rods and bearings below, head, cams and valves above, torqued to specification. Bolt-on items like manifolds, injectors and accessories are excluded, because the ones on your current engine move across during the changeover.
Which parts transfer from the old engine?
Intake and exhaust manifolds, the injection system, throttle body, alternator, starter, air conditioning compressor, mounts, sensors and the wiring loom all carry over. On high-kilometre vans it pays to replace tired ancillaries during the swap rather than send them back into service on a new engine.
Can fleet vehicles be VIN-checked before ordering?
Yes. Every sale includes a free VIN compatibility check, and fleet operators can submit multiple VINs for individual confirmation. Send the 17-character numbers by email or call 1300 200 320. Verification happens before invoicing, so the engine that arrives is correct for each specific vehicle.
What warranty applies to a commercial vehicle engine?
The same cover as all our engines: parts warranted for 12 months or 50,000 km, whichever comes first, with installation by a qualified mechanic as a condition. For a working van, note that 50,000 km can arrive quickly, so the kilometre limit is worth planning around.
What voids the warranty?
Overheating, as recorded by the heat tab fitted during assembly, is the key exclusion, because it results from cooling-system or installation faults rather than defects. Unqualified installation also voids cover. Keeping the radiator, fan and coolant in good order protects both engine and warranty.
How is delivery handled and what does it cost?
Delivery costs nothing on top of the engine price, anywhere in Australia. The engine ships in a secure crate direct to your workshop, depot or home. We book the freight once the VIN is confirmed and payment made, and you coordinate the installation around its arrival.
Why do G4KG engines in vans wear out, and is this one stronger?
Commercial duty is the short answer: heavy loads, long idling, stop-start running and stretched service intervals all accelerate bottom-end wear. The G4KG itself sat outside the overseas Theta II recall campaigns, but this replacement is upgraded internally against bottom-end wear anyway, with higher-grade rods, crankshaft, bearings and other reinforced parts fitted in place of the original-specification components.
Does the G4KG use a timing chain?
Yes, camshaft drive is by chain with no scheduled replacement, unlike belt-driven engines. Chain, guides and tensioner depend on regular oil changes for long life, which is worth enforcing in fleet maintenance schedules. The replacement engine arrives with its timing drive assembled and tested.
Is carbon build-up a problem on this engine?
Far less than on direct-injection engines. The G4KG uses multi-point injection, which sprays fuel over the intake valves and keeps them washed. That is one of the reasons the engine suits commercial use: fewer induction-cleaning jobs across a long working life.
Are these engines tested before they ship?
Every one. After assembly, each engine is hot and cold tested, verifying compression, oil pressure and mechanical noise at temperature and from cold. Engines that do not meet specification are rejected rather than crated, so tested performance backs every delivery.
Can our regular workshop install it, and is downtime predictable?
Any qualified mechanic or fleet workshop can do the installation with standard equipment; no dealer tooling is needed. Downtime becomes plannable because delivery is scheduled, the changeover is conventional, and our team is available on 1300 200 320 to resolve technical questions before the vehicle is booked in.
