This upper radiator hose is engineered to fit the 1UZ engine paired with NWT radiators, delivering OEM-quality performance and reliability. Constructed from EPDM tube with synthetic fiber knit reinforcement and a heat-, ozone-, and chemical-resistant EPDM cover, it resists collapse under vacuum and electrochemical degradation—the primary causes of hose failure. Pre-shaped for a precise fit, it ensures a secure seal and meets SAE 20R4 Class D2 and DIN 73411 Class A standards, providing durable, long-lasting protection for your vehicle’s coolant flow.
