The Vauxhall X 14 XE is a 1,389 cc, inline‑four naturally aspirated petrol engine produced between 1998 and 2005. It features multi‑point fuel injection, a single overhead camshaft (SOHC), and two valves per cylinder. In standard form it delivers 66 kW (90 PS) and 125 Nm of torque, prioritising simplicity and urban drivability.
Fitted to models such as the Corsa B, Astra G, and Tigra—including the 1.4 i variants—the X 14 XE was engineered for low — cost ownership and servicea…
All production years (1998–2005) meet Euro 3 standards .
The Vauxhall X 14 XE is a 1,389 cc inline‑four naturally aspirated petrol engineered for supermini and compact models (1998–2005). It combines multi-point fuel injection with SOHC architecture to deliver predictable urban performance and straightforward maintenance. Designed to meet Euro 3, it prioritises cost-effectiveness over peak output.

The Vauxhall X 14 XE was used across Vauxhall's Corsa B, Astra G, and Tigra platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Astra G for NVH control and modified airbox routing in the Tigra—and from 2002 the Corsa B adopted an updated timing belt tensioner, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The X 14 XE offers excellent simplicity and durability when maintained properly. Its main risk is timing belt failure if intervals are ignored—especially with pre-2002 tensioners. With timely belt changes every 60,000 km and correct oil, most engines exceed 200,000 km without major issues.
Top issues include timing belt tensioner failure, camshaft lobe wear from poor oil maintenance, coolant leaks from the plastic thermostat housing, and ignition coil failure. Tensioner and cam issues are addressed in Vauxhall service bulletins PI0215 and TIS-X14XE-07.
The X 14 XE powered the Corsa B (1998–2004), Astra G (1998–2005), and Tigra (1999–2004) in 1.4 i 90 PS form. It was not used in commercial vehicles or licensed to other manufacturers. All applications are transverse FWD layouts.
Limited potential. As a SOHC 8-valve engine, ECU remaps yield minimal gains (+3–5 kW). Significant power increases require forced induction or head swaps, which are rarely cost-effective. The engine is best suited to reliability over performance.
In a Corsa 1.4 i (90 PS), expect ~8.5 L/100km (city), ~5.8 L/100km (highway), or ~48 mpg UK combined. Real-world mixed driving typically returns 42–46 mpg UK. Economy is consistent but modest due to older engine architecture.
Yes. The X 14 XE is an interference engine. If the timing belt fails, pistons will contact open valves, causing severe internal damage. Strict adherence to 60,000 km or 4-year belt replacement is essential.
Vauxhall specifies ACEA A3/B3 10W-40 or 5W-30 mineral or synthetic oil. Extended drain intervals are not recommended. Change every 10,000 km or 12 months to protect cam lobes and bearings.
