This part is known as the engine belt , accessory belt , or serpentine belt ( or drive belt ). It is a reinforced rubber belt used in JAC GS3 (1.5L engine) and GA4 (1.5L engine) models from 2018 to 2024. Its primary function is to transmit power from the crankshaft pulley to all vital engine accessories, such as the alternator , air conditioning compressor , water pump , and possibly the power steering pump (if it is not electric) . This belt is essential for the operation of all these systems.
If you hear a sharp and continuous "squeaking" or "squeaking" sound coming from the front of the engine (especially when the air conditioner is on or when starting from a cold start), or if clear cracks appear on the surface of the belt, or if the battery or temperature light starts to illuminate, then the belt may be damaged or need tightening. If damaged, it must be replaced immediately to avoid the car stopping completely.
⚠️ Important Notice: Please make sure the part matches your vehicle's chassis number before purchasing the product or after ordering.
