Brand New G4NC 2.0L GDI Petrol Long Engine for Hyundai i40 VF 2012-2019

About this engine

The Hyundai i40 VF was the quiet achiever of the mid-size class: a sedan and Tourer wagon that racked up serious highway kilometres as a family car, fleet vehicle and country commuter between 2012 and 2019. Petrol i40 VF models factory-equipped with the G4NC carry a 2.0L GDI four-cylinder from the Nu engine family, and by now many of those engines have covered the kind of distance where wear starts to show.

Here you are buying a brand-new G4NC 2.0L GDI petrol long engine for the Hyundai i40 VF 2012-2019, manufactured to OEM specification rather than reconditioned from a worn core. Each unit is hot and cold tested after assembly, and its internals are strengthened beyond factory grade where the design’s weak points are documented.

The package includes a 12-month or 50,000 km parts warranty, free delivery anywhere in Australia, and a VIN compatibility check before purchase. Ring 1300 200 320 with your VIN and we will confirm fitment first.

Inside the i40's G4NC: background and known problems

Hyundai's Nu engine family covers the brand's mid-displacement four-cylinders, and the G4NC is its 2.0-litre direct-injection variant. Its close relatives are the G4NA, which uses multi-point injection at the same capacity, and the smaller 1.8-litre G4NB. All of them drive their camshafts by chain, so an i40 owner never faces a timing-belt interval.

In the i40 VF, the G4NC suited the car's character: smooth at freeway speeds, economical for its size, and refined enough for a vehicle pitched at long-distance comfort. Direct injection meters fuel straight into the combustion chamber, which sharpens efficiency but also means the intake valves never get rinsed by fuel spray. Across the industry, that is why GDI engines gradually collect carbon deposits on the intake side as the odometer grows.

The other pattern owners and workshops report on ageing Nu engines is oil consumption that creeps up with kilometres, sometimes accompanied by bottom-end noise once bearing and ring wear takes hold. An i40 that has spent a decade on the highway may run beautifully one year and start drinking oil the next.

When compression drops or a knock develops, the arithmetic tends to favour replacement over rebuild. A brand-new G4NC restores factory compression, factory oil control and a clean intake tract in a single operation, without the unknowns that come with a second-hand engine pulled from a wreck. Better still, these engines improve on the original where it counts: fitment matches OEM specification precisely, but the connecting rods, crankshaft, bearings and other internal components are a higher grade than the parts originally used, targeting the documented wear points directly.

Confirming fitment for your i40 VF

The i40 VF sold in Australia from 2012 to 2019 in sedan and Tourer body styles, and the range included diesel as well as petrol power depending on the year and trim. This long engine is specifically for i40 VF vehicles that were originally built with the G4NC 2.0L GDI petrol engine, so the first step is always confirming what your particular car left the factory with.

That confirmation costs you nothing. Read the VIN off your build plate, windscreen corner or registration certificate and pass it to us on 1300 200 320, or send it through in writing. We decode it, verify the original engine fitment, and give you a clear yes or no before you commit a dollar. If your i40 turns out to be a diesel or to carry a different petrol unit, we will say so and steer you toward the right engine instead of taking the sale.

It is also worth confirming the diagnosis before ordering. Low compression, heavy oil use and bottom-end knock all justify replacement, but a rattle can sometimes be an accessory or tensioner rather than the engine itself. A compression test and leak-down test at your workshop will settle the question quickly.

Once fitment and diagnosis line up, ordering takes minutes, and because your manifolds, injectors and accessories carry over to the new engine, your mechanic can quote the labour with confidence before the crate even arrives.

What arrives with the engine, and what happens next

This is a long engine: the fully assembled block, crankshaft, pistons, connecting rods and cylinder head, built up as one tested unit. Intake and exhaust manifolds, the injector set and fuel rail, alternator, starter, air-conditioning compressor and external sensors are not part of it, because those items swap over from the engine coming out of your i40. Any qualified workshop treats that transfer as routine.

Each G4NC is built to OEM fitment specification with upgraded internals, and after assembly every engine goes through hot and cold testing, so compression, oil pressure and gasket sealing are verified at operating temperature before the engine is crated.

Two warranty points deserve plain language. First, cover runs for 12 months or 50,000 km on parts, whichever comes first. Second, each engine carries a heat tab, and because the tab records any overheat event, damage from overheating is not covered; a healthy radiator, thermostat and properly bled cooling system are cheap insurance. Installation must be done by a qualified mechanic for the warranty to apply.

Freight is free to any address in Australia, including direct delivery to your workshop. The sequence is simple: VIN check, order, dispatch, installation. If you want a hand planning any step of it, 1300 200 320 puts you through to someone who deals with i40 engine replacements regularly.
