The Vauxhall Y22XE is a 2,198 cc, inline‑four naturally aspirated petrol engine produced between 1999 and 2005. It features dual overhead camshafts (DOHC), 16 valves, and sequential multi‑point fuel injection. In standard form it delivered 108 kW (147 PS) at 5,800 rpm and 205 Nm of torque at 4,000 rpm, providing smooth mid‑range response for everyday drivability.
Fitted to models such as the Vectra B (X20XEV replacement), Signum, and early Zafira A, the Y22XE was enginee…
All production years (1999–2005) meet Euro 3 standards .
The Vauxhall Y22XE is a 2,198 cc inline‑four naturally aspirated petrol engine engineered for mid‑size family vehicles (1999–2005). It combines DOHC architecture with sequential multi‑point fuel injection to deliver linear power delivery and smooth refinement. Designed to meet Euro 3 emissions standards, it balances drivability with moderate fuel consumption.

The Vauxhall Y22XE was used across Vauxhall's Vectra B and Signum platforms with longitudinal mounting and shared with Opel under GM’s global ECOTEC strategy. This engine received platform-specific adaptations—reinforced engine mounts in the Zafira A and revised intake manifolds in the Signum—and from 2003 the Z22XE direct-injection successor introduced aluminium-silicon block changes, creating interchange limits. 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 Y22XE offers smooth performance but has a known risk of cylinder head cracking if overheated. Early models (1999–2002) are more susceptible; later units saw minor casting improvements. With strict cooling system maintenance and timely oil changes using GM‑LL‑A‑025 oil, many engines exceed 200,000 km reliably.
Top issues include cylinder head cracking between exhaust valves, ignition coil pack failures, oil sludge from infrequent changes, and plastic thermostat housing leaks. These are documented in Vauxhall TSB‑01‑03‑07 and recurring MOT advisories related to cooling system integrity.
The Y22XE powered the Vectra B (1999–2002), Signum (2003–2005), and Zafira A (2000–2005) in 2.2i variants. It was also used in Opel equivalents (Vectra, Signum, Zafira) across Europe under GM’s shared ECOTEC platform.
Aftermarket ECU tuning is common on the Y-22-XE platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Vectra B 2.2i, expect ~9.5 L/100km (city), ~6.2 L/100km (highway), or ~30 mpg UK combined. Real-world mixed driving typically yields 28–33 mpg UK. Economy suffers if ignition or fuel trims are out of calibration.
Yes. The Y22XE is an interference engine. If the timing chain fails (rare but possible), pistons can contact open valves, causing catastrophic damage. However, the chain is robust and designed to last the engine’s lifetime with proper oil maintenance.
Vauxhall specifies SAE 10W‑40 or 5W‑40 synthetic oil meeting GM‑LL‑A‑025 standard. Always use a quality ACEA A3/B4‑compliant oil and change every 10,000 km or 12 months to prevent sludge and ensure valve train protection.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
Transparency in gaps
A missing or unverified value does not mean the manufacturer has withheld it. We distinguish information not yet verified, information not available to us, and information explicitly not disclosed by the source.
