This part is known as the engine oil cooler or engine oil cooler . It is a vital component in the engine lubrication system of JAC GS3, GS4, GS5, and GA4 vehicles. Its primary function is to lower the engine oil temperature using engine coolant (water) or atmospheric air as the coolant. Cooled engine oil maintains its viscosity and chemical properties, ensuring effective lubrication and protecting internal engine components from wear caused by excessive heat. This part from TAC PART is a high-quality replacement for the original part.
If internal damage occurs in the radiator, it may result in engine oil mixing with the coolant (and the appearance of a creamy substance in the coolant or oil cap), or an external oil leak may occur, requiring immediate replacement.
⚠️ Important Notice: Please make sure the part matches your vehicle's chassis number before purchasing the product or after ordering.
