G4NB Engine – Brand New 1.8L Petrol Long Engine for Kia Cerato YD

G4NB engine replacement for your Kia Cerato YD gives you a reliable way to get a worn or damaged engine back on the road without the uncertainty of rebuilding an old core. This brand-new 1.8L petrol long engine is designed for Kia Cerato YD models originally fitted with the G4NB engine and is supplied to OEM fitment specification, with upgraded internal components where the original design has known weaknesses.

This G4NB engine uses a 1.8L four-cylinder petrol configuration with multi-point fuel injection (MPI), along with dual continuously variable valve timing and a timing chain. The engine is supplied as a long engine, allowing your workshop to transfer the required manifolds, injectors, fuel rail and external accessories from your existing unit.

For Cerato YD owners, this G4NB engine replacement offers a fresh starting point rather than an unknown used motor. Each engine is hot and cold tested after assembly, fitted with a heat tab and built with higher-grade connecting rods, crankshaft and bearings. Fitment is confirmed against your VIN before dispatch, helping avoid the hassle and expense of ordering the wrong engine.

Features and Benefits

• Brand-New G4NB 1.8L Engine – Supplied new rather than as a used or rebuilt engine core, giving your Cerato a fresh foundation.
• OEM Fitment Specification – Designed to match the original G4NB installation for straightforward workshop replacement.
• Upgraded Internal Components – Higher-grade connecting rods, crankshaft and bearings provide improved durability compared with the original factory components.
• 1.8L Petrol MPI Configuration – Uses multi-point fuel injection and is suited to the factory G4NB application.
• Timing Chain Driven – Uses a timing chain rather than a conventional timing belt.
• Dual CVVT – Dual continuously variable valve timing helps optimise engine operation across different driving conditions.
• Hot and Cold Tested – Each engine undergoes testing after assembly to check operation, compression, oil pressure and sealing before dispatch.
• Heat Tab Fitted – Records exposure to excessive heat and helps monitor potential overheating events.
• VIN Fitment Check – Your vehicle identification number is checked before payment and dispatch to confirm the factory engine application.
• Free Australia-Wide Freight – Securely crated and shipped across Australia at no additional freight charge.
• Qualified Installation Required – Professional installation helps ensure correct fitment, commissioning and warranty compliance.

Get Your Cerato Back on the Road

When a high-kilometre engine starts burning excessive oil, losing compression or developing serious bottom-end noise, rebuilding the original motor can involve machining, replacement parts and uncertain costs. A brand-new G4NB engine removes much of that uncertainty by starting with new internal components and a tested assembly.

The long-engine design also makes the replacement process practical. Your workshop can transfer the compatible injectors, manifolds, alternator, starter, air-conditioning compressor, fuel rail and other external components from the existing engine. That means the installation can be planned around your actual vehicle rather than replacing parts that are still serviceable.

Before ordering, simply provide your 17-character VIN. The VIN can be found on the vehicle's build plate, through the windscreen on the driver's side, or on your registration documents. We will confirm that your Kia Cerato YD was originally fitted with the G4NB 1.8L petrol engine before the order proceeds.

Why Replace Instead of Rebuild?

A damaged G4NB can sometimes be rebuilt, but the final cost depends heavily on the condition of the original block, crankshaft, pistons, bearings and other internal components. A complete rebuild can also involve machining and additional parts once the engine has been stripped down.

With this G4NB engine replacement, the major internal components are supplied new, while the engine is built to OEM fitment requirements. That gives your workshop a clearer installation plan and avoids relying on the unknown history of a used engine.

Fitment and Installation

This engine is intended for Kia Cerato YD vehicles originally manufactured with the G4NB 1.8L petrol engine. Because the Cerato YD was available with different engine configurations, VIN verification is required before dispatch.

We recommend having the vehicle diagnosed by a qualified workshop before ordering. Compression and leak-down testing can help confirm whether engine replacement is required rather than an accessory, engine mount, exhaust or other component causing the symptoms.

Installation must be completed by a qualified mechanic. The cooling system should also be inspected and repaired where necessary before commissioning the replacement engine, as overheating can cause serious engine damage.

Warranty and Delivery

This engine comes with a 12-month or 50,000 km parts warranty, whichever occurs first, subject to the applicable installation requirements. Freight is free Australia-wide, with the engine securely crated for transport.
