Product Details

The Gates 21154 is a premium molded coolant hose engineered to OEM-quality specifications for reliable, long-lasting cooling system performance. Pre-shaped to fit and deliver perfectly sealed connections, this radiator hose is a direct replacement that saves time and cost compared to sourcing from an OE dealer.

Key Features:

  • EPDM tube construction with synthetic fiber knit reinforcement for durability and flexibility
  • Heat- and ozone-resistant EPDM cover for extended service life in demanding underhood environments
  • Engineered to resist electrochemical degradation (ECD) — the leading cause of coolant hose failure — preventing micro-cracks and unexpected hose failure
  • Resists vacuum collapse — specifically engineered materials reduce the need for internal springs in many applications
  • Temperature rated from -40°F to +275°F (-40°C to +135°C)
  • Meets SAE 20R4 EC Class D1 performance requirements
  • Pre-molded shape ensures a precise, leak-free fit
  • Approved for marine applications

Installation Note: Gates recommends replacing hose clamps each time a new coolant hose is installed. Not intended for fuel or oil transfer applications.
