Gates 18484 Small ID Molded Heater Hose 12.4in x 0.55in ID Black

The Gates 18484 is a factory-molded small inside diameter (Small I.D.) coolant heater hose designed as a direct OE replacement. With a centerline length of 12.4 inches and an inside diameter of 0.55 inches, this hose is precision-shaped to fit tightly engineered engine compartments and ensure a leak-free seal right out of the box.

• OE replacement fit — factory-molded to match original equipment specifications for a direct, no-modification installation

• Meets SAE 20R3 EC Class D1 standards
• Synthetic fiber knit reinforcement for added strength and vacuum collapse resistance

Gates recommends replacing hose clamps whenever a new coolant hose is installed to ensure a fully sealed cooling system.
