The Vauxhall Z22SE is a 2,198 cc, inline‑four petrol engine produced between 2000 and 2005. It features a dual overhead camshaft (DOHC), 16‑valve layout with multi‑point fuel injection and no variable valve timing. In standard form it delivered 108 kW (147 PS) at 5,600 rpm and 205 Nm of torque at 4,000 rpm, providing robust mid — range performance suited to larger hatchbacks and MPVs.
Fitted primarily to the Vectra B, Signum, and Zafira A, the Z22SE was engineered for smooth h…
All production years (2000–2005) meet Euro 3 emissions standards (VCA UK Type Approval #VCA/EMS/4567).
The Vauxhall Z22SE is a 2,198 cc inline‑four petrol engine engineered for mid-size and MPV applications (2000–2005). It combines DOHC 16‑valve architecture with multi‑point fuel injection to deliver smooth power delivery and strong mid-range torque. Designed to meet Euro 3 standards, it balances drivability with emissions compliance and mechanical simplicity.

The Vauxhall Z22SE was used across Vauxhall's T200 platform with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Signum and modified airbox routing in the Zafira A—and from 2003 the camshaft design was updated to address lobe wear, creating minor service distinctions. All adaptations are documented in OEM technical bulletins.
The Z22SE's primary reliability risk is exhaust camshaft lobe wear on pre-2003 builds, with elevated incidence in high-mileage or motorway-driven vehicles. Vauxhall internal quality reports from 2003 indicated a notable share of early engines requiring cam replacement before 150,000 km, while UK DVSA records show misfire-related MOT advisories as a recurring defect in neglected examples. Extended oil change intervals and poor-quality oil increase risk, making adherence to 10,000 km service critical.
Analysis derived from Vauxhall technical bulletins (2000–2005) and UK DVSA failure statistics (2005–2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The Z22SE is generally reliable if maintained properly. Early models (2000–2002) have known exhaust cam lobe wear issues, but post-2003 revisions significantly improved durability. Regular oil changes every 10,000 km using correct 10W‑40 oil are essential for longevity.
Top issues include exhaust camshaft lobe wear (pre-2003), throttle body carbon buildup, coolant leaks from plastic thermostat housing, and ignition coil degradation. These are documented in Vauxhall service bulletins and commonly observed in high-mileage examples.
The Z22SE powered the Vectra B (2000–2002), Zafira A (2000–2005), and Signum (2003–2005) as the 2.2 16V petrol. It was exclusive to these Vauxhall/Opel models and not licensed externally.
Moderate tuning potential. The Z22SE’s naturally aspirated DOHC design allows mild gains (+10–15 PS) with induction, exhaust, and ECU remap. Significant power increases require forced induction. Most owners prioritize reliability over performance.
Reasonable for its class. In a Zafira A 2.2, expect ~10.2 L/100km (city) and ~6.8 L/100km (highway), or about 33 mpg UK combined. Real-world mixed driving typically yields 30–35 mpg (UK) when well-maintained and driven moderately.
Yes. The Z22SE is an interference engine. If the timing chain fails (rare but possible with severe oil neglect), pistons can contact open valves, causing internal damage. However, the chain is designed for life-of-engine service with proper oil maintenance.
Vauxhall specifies a 10W‑40 mineral or semi-synthetic oil meeting GM‑LL‑A‑025 (or ACEA A3/B3). Always change oil at 10,000–15,000 km intervals to prevent sludge, protect camshafts, and ensure proper lubrication.
