This part, known as the cylinder head gasket or cylinder head seal , is a vital consumable component that fits between the engine block and the cylinder head in JAC GS4 (2018-2021) and GS3 (2018-2023) vehicles. Its primary function is to create a tight seal between the two metal surfaces to prevent leakage.
This seal is necessary to maintain the proper pressure for combustion and to prevent the fluids from mixing with each other.
Signs of a damaged cylinder head gasket include: excessive and persistent engine overheating , air bubbles in the radiator , thick white smoke coming from the exhaust , or oil mixing with coolant (a white/creamy substance in the oil cap) .
⚠️ Important Notice: Please make sure the part matches your vehicle's chassis number before purchasing the product or after ordering.
