Overview & Design Features
The SQRE4G15C engine is a 1.5-liter naturally aspirated inline-four gasoline engine developed by Chery Automobile under its ACTECO engine family. As Jetour operates as a specialized sub-brand of Chery, this powerplant is widely utilized across various compact SUVs and crossovers within the brand’s portfolio. Known for its balance of thermal efficiency and manufacturing cost-effectiveness, this engine represents a modern refinement of Chery’s established small-displacement engine architecture, offering dependable performance for urban commuters.
From an engineering perspective, the SQRE4G15C features a robust cast-iron cylinder block paired with a lightweight aluminum alloy cylinder head. This configuration ensures exceptional structural integrity and resistance to thermal warping under heavy loads. The engine employs a dual overhead camshaft (DOHC) valvetrain with 16 valves, controlled by a Dual Variable Valve Timing (DVVT) system that optimizes both low-end torque and high-RPM efficiency. Unlike many modern direct-injection engines, the SQRE4G15C utilizes a multi-point fuel injection (MPI) system, which significantly reduces intake valve carbon deposit issues.
This specific engine model has been widely integrated into various entry-level and mid-tier trims of Jetour and Chery vehicles. Primary models utilizing the SQRE4G15C include the Jetour X70 (base manual variants), Jetour Dashing, Chery Tiggo 4, Chery Tiggo 4 Pro, and the Chery Arrizo 5 sedan. Production of this engine variant commenced around 2019 and continues to serve as a staple powertrain for budget-conscious markets globally.

Common Problems & Reliability
- Ignition System Sensitivity: The factory ignition coils and spark plugs can experience premature wear, occasionally leading to minor engine misfires, rough idling, or a reduction in fuel economy. Replacing these components with high-quality aftermarket alternatives generally resolves the issue.
- Throttle Body Carbon Accumulation: Due to the nature of the crankcase ventilation system, carbon deposits can accumulate on the electronic throttle body plate over time. This typically manifests as a fluctuating idle speed and requires periodic cleaning.
- Valve Cover Gasket Leaks: At higher mileages, some units exhibit minor oil weeping around the valve cover gasket. While not a catastrophic failure, it requires timely replacement to prevent oil from entering the spark plug wells.
In terms of overall longevity, the SQRE4G15C is considered highly durable. Due to its cast-iron block and conservative power tuning, this engine boasts an expected service life of 250,000 to 300,000 kilometers before requiring a major mechanical overhaul, provided it is subjected to routine, high-quality maintenance.
Maintenance Tips & Service Schedule
- Engine Oil Changes: Perform oil and filter changes every 8,000 to 10,000 kilometers. It is highly recommended to use fully synthetic 5W-30 viscosity oil for moderate climates, or 0W-20 for regions experiencing extreme winter temperatures.
- Spark Plug Replacement: Replace the standard spark plugs every 30,000 to 40,000 kilometers to maintain ignition efficiency and prevent unnecessary load on the ignition coils.
- Timing Chain Inspection: The engine utilizes a durable metal timing chain instead of a rubber belt. While it does not require routine replacement, a physical inspection of the tensioner and chain wear should be conducted around the 150,000-kilometer mark.
- Cooling System Maintenance: Flush and replace the engine coolant every 60,000 kilometers or 3 years using high-quality ethylene glycol-based fluid to protect the aluminum cylinder head from internal corrosion.
Conclusion
The Jetour SQRE4G15C engine stands out as an exceptionally sensible and low-risk option for used vehicle buyers. By eschewing complex modern features such as high-pressure turbochargers and direct gasoline injection, this power unit avoids the costly repairs and carbon buildup issues often associated with downsized turbocharged engines. Its straightforward multi-point injection system, heavy-duty cast-iron block, and widespread parts availability make it both cheap to maintain and easy to repair. For buyers prioritizing long-term mechanical simplicity and daily reliability over high-speed performance, a vehicle equipped with the SQRE4G15C is a highly recommended purchase.
