Specifications, Common weaknesses and Maintenance.

The K15B is a 1.5-litre, inline-four petrol engine equipped with multi-point fuel injection and variable valve timing for improved efficiency. It produces a balance of power and economy suitable for compact MPVs, sedans, and crossovers. With output figures generally around 77–79 kW and 138–140 Nm of torque depending on the model year and variant, it delivers smooth mid-range performance and dependable daily driving characteristics. The engine is lightweight, easy to maintain, and supported by widely available service parts, making it a practical option for workshops and private vehicle owners.

Like any engine, the Suzuki K15B 1.5L petrol engine has a few common weaknesses. Some drivers report higher-than-expected fuel consumption when the engine is paired with older 4-speed automatic transmissions, though this is vehicle-specific rather than an engine defect. Mild oil sweating around the rocker cover gasket may occur with age, but this is inexpensive to fix. Regular oil changes, clean air filtration, and timely spark-plug replacements help the K15B maintain smooth operation. 

Carbon buildup in the intake system can occur over extended mileage, especially with poor fuel quality, but routine servicing prevents performance loss. Overall, with proper maintenance, the Suzuki K15B engine is known to deliver exceptional longevity, making it a strong investment for any Suzuki owner needing a reliable replacement engine.
