Engine spare parts ensure long service life and reliability. Engineering Machinery Ship Engine Parts Oil Control Valve 3071599. Spare parts undergo a 105°C high-temperature steam test to ensure quality and durability. Optimizes the vehicle's cold-start coolant circulation logic, effectively shortening engine warm-up time, rapidly increasing engine temperature, and significantly improving start-up and operation in low-temperature environments. In summer, it can precisely block the heating duct circulation path, preventing residual heat from penetrating the engine compartment and helping to improve the vehicle's air conditioning cooling effect, thus comprehensively optimizing the driving and riding comfort experience., Manufacturer: JHYTVBMLOI
