Common weaknesses and Maintenance.

Like any modern diesel engine, the G4FB comes with a few known weaknesses that should be monitored.

Injectors may also require attention after high mileage, and neglecting fuel filter replacement can lead to pressure buildup in the fuel system. 

 However, most of these issues are preventable with proper maintenance. To ensure long engine life, owners should follow strict maintenance practices such as using high-quality diesel, performing oil changes every 10,000 km, replacing the air and fuel filters on time, and periodically inspecting the EGR and turbo system. When properly cared for, the Hyundai G4FB 1.6L diesel engine remains one of the most reliable and economical engines in its class.
