HFC4GB3-3D 1.6L Bare Engine / Long Block – JAC Replacement Engine
This HFC4GB3-3D bare engine is a complete long block assembly built to OEM specifications for JAC vehicles. It is the 1.6-litre naturally aspirated gasoline engine from JAC’s 4GB series (Ruijiete brand), independently developed and produced by Anhui Jianghuai Automobile Group.
