Brand New G4NA 2.0L Petrol Engine for Kia Cerato YD 2016-2018

About this engine

This is a brand-new G4NA 2.0L petrol engine for the Kia Cerato YD, suiting cars built between 2016 and 2018. If your Cerato’s engine has worn to the point of heavy oil use, knocking or outright failure, fitting a new G4NA is the one repair that removes the problem instead of postponing it.

The engine is built to full OEM fitment specification, with upgraded internal components where the G4NA design has documented weak spots, and no unit leaves without passing hot and cold testing. Parts are warranted for 12 months or 50,000 km, whichever comes first, and freight is included Australia-wide. Fitment is never guesswork: we check your VIN before the engine is dispatched, so what arrives at your workshop is confirmed for your exact car. Ring 1300 200 320 with the VIN handy and the check takes only a few minutes.

Common G4NA faults, and when fixing them stops adding up

Cerato YD owners usually arrive at this decision through a repair quote. The car has been reliable transport for years, then the workshop finds low compression, worn bearings or an oil consumption habit that keeps getting worse, and suddenly there is a number on the table that demands a serious think.

The G4NA's track record explains the pattern. In examples that have covered big kilometres, excessive oil consumption and wear in the bottom end are commonly seen, and that kind of internal wear cannot be fixed from the outside. There is no additive, sensor or minor service that restores worn bores and bearings.

Weighing the options is where a new engine pulls ahead. A partial repair leaves the rest of the worn engine in place, so the next failure is already loaded. A full rebuild depends heavily on machine-shop quality and can approach new-engine money once every worn part is honestly accounted for. A used engine from a wrecker is the same design at unknown kilometres, quite possibly on the same wear trajectory that ended your original. Against those choices, a brand-new engine at a fixed price, tested before dispatch and covered by a proper warranty, is the tidiest way to spend the money once.

The rest of the car seals the argument. A Cerato of this age typically has a sound body, comfortable interior and cheap running costs. Give it a new engine and it goes back to being exactly the low-drama car you bought.

Port injection, chain drive and nothing second-hand

The G4NA sits in Hyundai and Kia's Nu engine family: a 2.0-litre, naturally aspirated four-cylinder that powered the Cerato YD sold here from 2016 to 2018. Two design details are worth knowing as an owner. First, it uses multi-point (port) fuel injection, so it is not prone to the intake-valve carbon build-up that affects the direct-injection G4NC from the same family. Second, its camshafts are driven by a timing chain, which means no belt replacement bills across the life of the engine.

Now the engine itself. Each replacement unit is built from all-new components, and this is not a recondition: there is no second-hand block, no re-ground crank, no skimmed head. It is made to OEM fitment specification, meaning everything lines up as factory during installation, yet inside it departs from the original on purpose. Components tied to the design's documented weaknesses, the connecting rods, crankshaft and bearings among them, are upgraded to a higher grade, so the wear pattern that ended your original engine is designed out of its replacement.

Verification happens twice before your money is at stake. The engine is hot and cold tested after assembly, confirming compression, oil pressure and running behaviour on the specific unit you will receive, and it carries a heat tab so any future overheating event is recorded permanently. Then your VIN is checked against the listing. Kia built the YD range with more than one engine option, and the VIN is the only reliable way to identify which one your car uses. Send it through by phone or email; if this engine is not the right match, we say so before dispatch and point you toward the correct unit instead.

What arrives, what transfers, what's covered

Your delivery contains a long engine: the assembled and tested combination of block, cylinder head and all internal components, from the crankshaft to the valvetrain. It deliberately excludes bolt-on externals. The manifolds, injectors, throttle body, sensors, alternator, air conditioning compressor and brackets on your current engine are all compatible and transfer straight across, which is why the long-engine format is the most cost-effective way to do this job.

Freight is free to every corner of Australia. The engine ships palletised, and most buyers have it delivered directly to their installing workshop to keep handling to a minimum.

On installation: it must be performed by a qualified mechanic for the warranty to stand. A good workshop will treat first start-up seriously, with new oil and filter, fresh coolant, a flushed and pressure-tested cooling system, and a check of the radiator, thermostat and hoses. If a lubrication or cooling fault contributed to the old engine's death, that fault gets fixed before the new engine runs.

Warranty cover is 12 months or 50,000 km on parts, whichever arrives first. The exclusions are the honest ones: overheating, which the heat tab records, and installation that was not carried out professionally. Keep the invoice and service your Cerato normally, and the coverage simply sits in the background.

Any doubts, call 1300 200 320 before ordering. A short conversation now is worth more than a freight claim later.
