Brand New G4KE 2.4L MPI Petrol Long Engine for Hyundai Santa Fe

About this engine

Here is a brand-new G4KE 2.4L MPI petrol long engine for the Hyundai Santa Fe, built for owners who want their family SUV fixed once, properly. If the original G4KE in your Santa Fe has developed a bottom-end knock, lost oil pressure or seized outright, a new engine restores the vehicle without inheriting anyone else’s wear.

Every unit is built from all-new parts to OEM fitment specification — with internal upgrades where the original design proved fragile — and no engine ships until it has passed both a hot test and a cold test. The package includes free freight to any Australian address and a parts warranty of 12 months or 50,000 km, and we confirm compatibility against your VIN — free — before you buy. This page walks through the replacement decision, the Theta II engine family behind the G4KE, and how the supply and installation process works. For anything specific, ring 1300 200 320.

When a Santa Fe needs more than a repair

Some engine problems are worth fixing individually — a leaking rocker cover, a tired coil pack, a noisy pulley. Others announce that the engine as a unit is finished. For the G4KE, the second category shows up as a hard metallic knock from deep in the block, an oil light flickering at idle, glitter in the drained oil, or a crank that suddenly will not rotate.

Owners sometimes ask whether just the bearings can be done. Mechanically it is possible; economically it rarely makes sense. By the time bearings knock, debris has usually toured the entire oiling circuit, and the crank journals and block surfaces are compromised. Machining, parts and labour on the old engine can approach the cost of a new one, without new-engine durability at the end of it.

The Santa Fe itself is usually the argument for doing the job properly. It is a seven-seat-capable family SUV that many households rely on daily, and a straight, well-kept example has years of usefulness left. Swapping in a used engine of the same age and design merely rewinds the failure by a couple of years. Fitting a new long engine, with every wear component at zero hours, is the version of the repair that lets you stop thinking about the engine altogether — which, for a family car, is really the point.

Theta II known issues: what fails, and what this engine does about it

Theta II is the name of the engine family, and G4KE is the specific member fitted to petrol Santa Fe models of this era. Hyundai and Kia used the Theta II platform across a wide slice of their range, in four main forms: the 2.4-litre multi-point-injected G4KE you are looking at, the direct-injected G4KJ of the same capacity, a turbocharged 2.0-litre GDI designated G4KH, and the G4KG. Every version pairs an aluminium block with twin overhead cams, 16 valves and a timing chain.

For a Santa Fe owner, the G4KE's defining feature is its multi-point injection. Fuel is delivered into the intake ports rather than directly into the cylinders, a proven arrangement that keeps the fuel system simple and — as a side benefit — continually rinses the intake valves, so the valve carbon accumulation associated with direct-injection engines stays largely off the menu. Servicing costs on the injection side are modest as a result.

Honesty requires covering the family's known weakness too. High-kilometre Theta II engines have a documented history of rod-bearing wear, significant enough to prompt recall campaigns and extended warranty programs in certain markets. Not every engine is affected, and careful oil maintenance helps, but the failure mode is terminal for the engine when it strikes. A newly manufactured G4KE answers that history directly — and this one answers it twice over. Fitment follows the OEM specification, while the connecting rods, crankshaft, bearings and other internal parts are upgraded to a higher grade than the originals, reinforcing precisely the area the family's record calls out.

Inclusions, freight and fitting

The term long engine describes the scope precisely: you receive the engine block and cylinder head fully assembled, containing the crankshaft, pistons, connecting rods, bearings, camshafts and complete valvetrain. Everything that bolts to the outside — inlet and exhaust manifolds, injectors, sensors, the alternator, compressor, pumps and brackets — is retained from your existing engine and swapped across by your installer.

Ordering starts with the VIN check. Send the number through on 1300 200 320 or via the site, and we verify the engine against your Santa Fe's specification before taking payment. It costs nothing and eliminates fitment surprises entirely.

Dispatch follows testing. Hot and cold running checks confirm oil pressure, compression and general health, after which a heat tab is applied to the block and the engine is crated. Freight is free Australia-wide, straight to your workshop of choice.

On the warranty: parts are covered for 12 months or 50,000 km, whichever is reached first, conditional on installation by a qualified mechanic. The heat tab is the firm line in the terms — an overheated engine is not covered, so have your installer go through the cooling system thoroughly and replace anything marginal while the bay is empty. A gentle running-in period and an early first oil change complete the picture, and your Santa Fe goes back to being the low-drama family truck it was built to be.
