Product Details

The Gates 21578 is a curved lower radiator coolant hose designed as a direct OE replacement for a precise, leak-free fit. With a 1.25-inch inner diameter and a 23.7-inch centerline length, this hose routes coolant from the engine pipe to the radiator, maintaining proper coolant flow and engine temperature regulation.

Gates engineers their coolant hoses to meet or exceed original equipment specifications, using high-quality rubber compounds that resist heat, pressure, electrochemical degradation (ECD), and ozone cracking — common failure points on aging hoses.

Key Features:

  • Type: Curved lower radiator coolant hose
  • Inner Diameter (I.D.): 1.25 in.
  • Centerline Length: 23.7 in.
  • Location: Lower (pipe to radiator)
  • Color/Finish: Black
  • Fit: OE replacement — direct drop-in installation
  • Sold: Individually
  • Warranty: Lifetime Gates limited warranty

Gates is a globally recognized leader in automotive belts and hoses, trusted by professional technicians and DIY enthusiasts alike. The 21578 is sold individually and backed by a lifetime limited warranty for long-term peace of mind.
