Chery SQR484F Engine original parts

Reliable SQR484F 2.0L Engine for Chery Eastar, A5, V5, Riich, Tiggo 5 & 3 – High-Performance ACTECO Powertrain

The SQR484F is a robust and fuel-efficient 2.0-liter inline-four gasoline engine developed by Chery Automobile as part of its pioneering ACTECO series. Introduced around 2008, this engine marked a significant advancement in Chinese automotive engineering, offering improved performance, better thermal efficiency, and enhanced durability compared to earlier models. Designed with modern materials and technologies, the SQR484F delivers consistent power output while maintaining excellent reliability—making it a trusted choice for both OEM applications and aftermarket replacements across multiple Chery vehicle platforms.

This engine features dual overhead camshafts (DOHC), variable valve timing (VVT) technology, and an aluminum cylinder block in its original configuration—a design that emphasizes lightweight construction and efficient heat dissipation. With a peak power output of 102 kW (approximately 139 horsepower) and maximum torque reaching 180 Nm, the SQR484F provides responsive acceleration and smooth highway cruising. It’s especially well-suited for manual transmission setups like the MTQR512MH gearbox, ensuring precise control and optimal drivetrain synergy.

Key technical highlights include advanced combustion chamber design, optimized intake manifold geometry, and a high-flow fuel delivery system—all contributing to improved fuel economy and reduced emissions. While early versions utilized an aluminum engine block for weight savings and thermal management, later production models transitioned to cast iron for cost-efficiency without compromising core functionality. This evolution reflects Chery’s commitment to balancing innovation with practical manufacturing considerations.

The SQR484F long block or complete engine assembly serves as a direct replacement option for various Chery models, including the Eastar, A5, V5, Riich, Tiggo 5, and Tiggo 3. Whether you're restoring a classic Chery sedan or upgrading a fleet vehicle, this engine offers proven reliability, easy installation, and compatibility with existing vehicle systems. Its modular architecture allows for straightforward integration into similar platforms, reducing downtime during maintenance or engine swaps.

Users appreciate the SQR484F's balance between affordability and performance. Many owners report smoother idling, reduced vibration, and improved throttle response after replacing worn-out units with a rebuilt or new SQR484F engine. The inclusion of VVT technology ensures that the engine maintains optimal air-fuel mixture across varying RPM ranges, enhancing both low-end torque and high-speed efficiency—an ideal feature for urban driving and long-distance travel alike.

Common inquiries often focus on compatibility, rebuild options, and expected lifespan. Most mechanics confirm that with proper servicing—including regular oil changes, spark plug replacement, and coolant checks—the SQR484F can last over 150,000 kilometers (93,000 miles). For those seeking a durable alternative to factory engines, this unit offers a compelling blend of performance, longevity, and value.

Whether you’re a professional mechanic, a DIY enthusiast, or a fleet manager looking for dependable powertrains, the SQR484F remains a top-tier solution for Chery-based vehicles worldwide. Its legacy as one of Chery’s first mass-produced aluminum-block engines underscores its role in shaping modern Chinese automotive standards—and continues to support global demand for reliable, high-quality internal combustion units.
