Product Description
Confirm Compatibility
All parts are 100% compatible with Yuchai YC4S140-48(S56D1) turbocharged diesel engine. With 3.8L displacement, 103kW rated power, and Euro IV compliance, this engine is widely used in medium/light-duty trucks and 4×2 vans. Our parts are tailored for its low-noise, fuel-efficient (199g/kW·h) design, meeting routine maintenance and emergency repair needs.
Parts Coverage
Our parts cover core systems of the engine: power core (cylinder block, piston, crankshaft damper), fuel & emission (injection pump, turbocharger, EGR), lubrication & cooling (oil pump, filter, water pump), and electrical & auxiliary (alternator, starter, ECU). EWP-marked wear parts are easy to identify.
