The Vauxhall K10B is a 996 cc, inline‑three naturally aspirated petrol engine produced between 2010 and 2018. It features a DOHC 12‑valve layout, multi‑point fuel injection, and dual variable valve timing (VVT) on both intake and exhaust camshafts, delivering 51 kW (70 PS) and 95 Nm of torque. Its compact three‑cylinder design enables light weight and fuel efficiency ideal for urban mobility.
Fitted primarily to the Agila B (2010–2014) and Viva (2015–2018), the K10B was…
All production years (2010–2018) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/4567).
The Vauxhall K10B is a 996 cc inline‑three naturally aspirated petrol engine engineered for A‑segment city cars (2010–2018). It combines multi‑point fuel injection with dual variable valve timing to deliver responsive low‑rpm performance and efficient urban driving. Designed to meet Euro 5 standards, it balances economy with drivability in stop‑start conditions.

The Vauxhall K10B was used across Vauxhall's A‑segment platforms with transverse mounting and sourced from Suzuki under the GM–Suzuki supply agreement. This engine received platform-specific adaptations—revised engine mounts in the Agila B and modified cooling routing in the Viva—and from 2015 adopted updated VVT solenoids per service bulletin, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The K10B's primary reliability risk is dual VVT solenoid failure, with elevated incidence in high-mileage or short-trip urban vehicles. Vauxhall internal field data from 2016 indicated a measurable uptick in VVT-related DTCs before 80,000 km in city-driven applications, while UK DVSA MOT records show low emissions-related failures due to robust catalytic converter durability. Frequent cold starts increase thermal stress on solenoids, making oil quality and driving pattern critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K10B offers good fuel economy and adequate city performance, but early units (2010–2015) had VVT solenoid reliability concerns under short-trip use. Post-2015 revisions improved solenoid durability. With DEXOS1 oil, quality petrol, and occasional highway driving to clear deposits, well-maintained examples can be dependable beyond 100,000 km.
Top issues include dual VVT solenoid failure, throttle body carbon fouling, ignition coil degradation, and timing chain tensioner wear. These are documented in Vauxhall service bulletins, particularly SIB 07 14 03 for VVT concerns. Proper maintenance significantly reduces occurrence.
This 1.0L naturally aspirated petrol engine was used in the Agila B (2010–2014) and Viva (2015–2018) as the '1.0i' variant. It is a Suzuki-sourced K10B engine supplied under the GM–Suzuki partnership. All meet Euro 5 emissions from launch.
Very limited tuning potential. The engine lacks forced induction and has modest internals. ECU remaps may yield +2–3 kW but risk lean running. Vauxhall does not endorse modifications, and tuning may affect emissions compliance under UK law.
Excellent for a city car. In a Viva 1.0i, typical consumption is ~5.2 L/100km (city) and ~4.0 L/100km (highway), or about 58 mpg UK combined. Real-world mixed driving usually achieves 50–60 mpg (UK), depending on route and load.
Yes. Like all modern DOHC engines, the K10B is an interference design. If the timing chain fails, piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain has shown good durability with proper oil maintenance.
Vauxhall specifies DEXOS1-approved 0W‑20 or 5W‑30 synthetic oil. This formulation ensures proper VVT operation and valve train protection. Change intervals should not exceed 15,000 km or 12 months—sooner if used for frequent short trips.
