Brand New G4FC 1.6L Petrol 4 Cylinder Engine for Hyundai i20 2010-2015

About this engine

A Hyundai i20 that has begun blowing smoke on start-up, topping itself up with oil or running rough under load is usually telling you its G4FC has done its dash. For the 2010-2015 i20, the maths of major engine repair rarely stacks up against fitting a new unit, which is why many owners land here. On offer is a brand-new G4FC 1.6L four-cylinder petrol engine for the Hyundai i20 2010-2015, manufactured to OEM specification rather than rebuilt from worn cores.

Each engine goes through hot and cold testing after assembly, before it is cleared for dispatch. Parts warranty is 12 months or 50,000 km — whichever is reached first — freight to anywhere in Australia costs nothing, and we match the engine against your VIN before it leaves. Questions? Ring 1300 200 320.

Common G4FC trouble spots in the i20

Small hatchbacks like the i20 spend their lives in stop-start traffic, and that duty cycle is hard on an engine. Short trips mean the oil rarely gets hot enough to burn off moisture and fuel dilution, and skipped services compound the damage. Over enough years the usual suspects show up: oil consumption from tired rings and seals, a noisy timing chain that has stretched on degraded oil, or a cooked head gasket after a cooling system let go on a hot day.

At that stage there are three doors. Door one is a rebuild — but stripping, machining and re-assembling a G4FC involves so many labour hours and machine-shop operations that the invoice frequently rivals a new engine, with no guarantee of what condition the block and head are in until they are apart. Door two is a used engine, which is cheap upfront but arrives with unknown kilometres, unknown servicing and often no meaningful comeback if it fails. Door three is a brand-new engine at a known, fixed price.

For an i20 with a solid body and a healthy transmission, door three is generally the one that makes financial sense. The car itself is economical to run and cheap to register and insure, so giving it a fresh heart extends its useful life by years at a cost well below changing cars. You also start with a genuinely blank slate: zero kilometres on every internal component.

The G4FC long engine, explained

G4FC is the code Hyundai gave the 1.6-litre multi-point injected petrol four in its Gamma engine family. The Gamma range spans several capacities and injection layouts, but the G4FC is the port-injected 1.6, and it is the version fitted to the i20 covered by this listing — the 2010 to 2015 cars. Port injection is a quiet advantage at high kilometres: fuel spraying onto the back of the intake valves keeps them clean, so the carbon accumulation that plagues direct-injected engines is far less of a factor here.

Valve timing is driven by a chain, not a belt, so there is no periodic belt-and-tensioner job in the service schedule. The engine asks for little beyond oil changes done on time with the right grade, a clean air filter and a cooling system that holds pressure.

One more thing separates this unit from the engine coming out of your car. It is manufactured to OEM fitment specification so everything lines up during installation, yet the internals are upgraded wherever the factory design showed documented weaknesses — stronger connecting rods, crankshaft and bearings are among the changes. The idea is simple: keep the fitment, fix the flaws.

One caution before ordering anything: engine codes are necessary but not always sufficient. Across a five-year production run there can be detail changes to brackets, sensors and fittings, and two i20s from different build months are not automatically identical under the bonnet. That is why we ask for your VIN before dispatch. We run the number, confirm this exact engine suits your exact car, and only then book the freight. If the check turns up a mismatch, you find out before money and time are spent — not after the old engine is already out on the workshop floor.

Freight, warranty and the install

What you receive is a long engine — the assembled bottom end plus cylinder head, tested as a complete rotating unit. The definition matters when you brief your mechanic: manifolds, injectors, ignition components, the alternator, the starter and the various sensors are all carried over from your current engine. Budget a little extra for the consumables worth renewing while access is easy — coolant, thermostat, drive belts and possibly engine mounts.

Every engine is hot and cold tested once assembly is finished, meaning it has been run, checked for leaks, pressure and noise, and signed off before crating. A heat tab on the block records any subsequent overheating: if the tab has melted, warranty on heat-related damage is off the table, so make sure the cooling system on your i20 is sorted before the swap. Outside that exclusion, cover is 12 months or 50,000 km on parts, whichever arrives first, conditional on installation by a qualified mechanic.

Delivery is free to any address in Australia. Most customers have the crate sent straight to their chosen workshop, which we recommend — the receiving mechanic can inspect it on arrival and plan the job. To lock in a compatibility check, get a freight estimate for timing, or ask anything about the warranty fine print, call 1300 200 320 with your VIN and rego details at hand.
