This part , known as the engine water radiator or radiator , is the most important component in the engine cooling system of JAC GS3 and GS4 vehicles (2018-2023 models). It consists of a large network of pipes and metal fins. Its primary function is to dissipate heat from the hot coolant (which has drawn heat from the engine). Cool air passes through its fins while the vehicle is in motion (or with the help of a cooling fan), lowering the coolant temperature before it is returned to the engine.
If you notice a continuous and unjustified rise in the engine temperature gauge, or a clear leak of coolant from the radiator (especially from the side plastic parts or grille fins), this indicates damage or blockage in the radiator and the need for immediate replacement.
⚠️ Important Notice: Please ensure that the part matches your vehicle's chassis number before purchasing the product or after ordering, due to the possibility of dimension differences between 1.3L and 1.5L engines.
