The Daewoo F16S3 is a 1,598 cc, inline-four petrol engine produced between 2010 and 2015. It features multi-point fuel injection (MPFI), dual overhead camshafts (DOHC), and 16 valves, delivering balanced performance and fuel efficiency in compact vehicles. In standard tune it produces 81 kW (110 PS) and 150 Nm of torque, making it suitable for everyday driving with responsive mid-range power delivery.
Fitted to models such as the Daewoo Gentra and Chevrolet Aveo (third generation), the F16S3 was engineered for smooth operation and cost-effective ownership. Emissions compliance was achieved through a three-way catalytic converter and closed-loop lambda control, allowing Euro 5 compliance across all production years.
One documented reliability concern is premature wear of the timing belt tensioner, particularly in vehicles subjected to high-temperature operation or extended service intervals. This issue, highlighted in GM Korea Service Information Bulletin 10-021B, is linked to early tensioner design limitations. In 2012, an updated tensioner with improved polymer materials was introduced to enhance durability and reduce failure risk.

Production years 2010–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7890).
The Daewoo F16S3 is a 1,598 cc inline-four petrol engine engineered for compact sedans and hatchbacks (2010–2015). It combines MPFI with DOHC 16-valve architecture to deliver refined performance and efficient fuel consumption. Designed to meet Euro 5 emissions standards, it serves as a modern, reliable powertrain for urban and highway use.

The naturally aspirated DOHC design provides smooth, linear throttle response ideal for daily driving but requires strict adherence to 90,000 km timing belt replacement intervals to prevent interference engine damage. SAE 5W-30 API SM/CF oil is recommended for optimal valve train and bearing protection. Extended idling in hot climates may contribute to tensioner degradation. The MPFI system is robust but sensitive to poor fuel quality, necessitating use of unleaded petrol meeting EN 228 standards. Post-2012 models benefit from upgraded tensioner materials; pre-2012 units should be inspected per GM Korea SIB 10-021B. Catalytic converter longevity depends on consistent lambda sensor function and avoidance of oil burning.
Oil Specs: Requires SAE 5W-30, API SM/CF specification (GM Korea SIB 10-021B). Compatible with ACEA A1/B1.
Emissions: Euro 5 certification applies to all 2010–2015 models (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under ECE R85 standards. Output consistent across all markets (GM Korea PT-2012).

The Daewoo F16S3 was used across Daewoo's Gentra and Chevrolet's Aveo platforms with transverse mounting and shared GM Korea architecture. This engine received platform-specific adaptations-reinforced mounts in the Gentra and revised ECU tuning in the Aveo-and from 2013 the facelifted Aveo adopted the F16S3 with updated emissions calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front timing cover below the valve cover (Daewoo TIS F1680). The 8th VIN digit indicates engine type ('F' for F16S3). Pre-2012 models have silver valve covers with black plastic covers; post-2012 units use black valve covers. Critical differentiation from F14S: F16S3 has larger displacement and uses a timing belt, while F14S is a smaller 1.4L with similar configuration. Service parts require production date verification—timing kits for engines before 05/2012 are incompatible with later units due to tensioner redesign (GM Korea SIB 10-021B).
The F16S3's primary reliability risk is timing belt tensioner wear on early builds, with elevated incidence in hot climates and extended service conditions. Internal GM Korea reports from 2011 indicated a notable number of pre-2012 engines requiring belt replacement before 90,000 km, while UK DVSA records show timing-related failures as a leading cause of MOT rejection for imported models. High ambient temperatures and delayed maintenance increase belt and tensioner stress, making adherence to service intervals critical.
