Gates 21570 Premium Molded Coolant Hose

The Gates 21570 Premium Molded Coolant Hose is a pre-shaped upper radiator hose engineered to deliver OEM-quality performance and reliable cooling system operation. This curved hose features advanced EPDM construction designed to resist the most common causes of coolant hose failure in demanding automotive applications.

Key Features:

• EPDM Construction: Features an EPDM tube with synthetic fiber knit reinforcement and a heat-, ozone-, and chemical coolant-resistant EPDM cover for long-lasting durability
• Pre-Shaped Design: Molded to exact specifications to ensure proper fit and perfectly sealed conditions, eliminating guesswork during installation
• Electrochemical Degradation Resistance: Specifically engineered to resist electrochemical degradation, the leading cause of coolant hose failure
• Vacuum Collapse Resistance: Advanced materials prevent collapse under vacuum conditions, maintaining consistent coolant flow
• Wide Temperature Range: Operates reliably from -40°F to +257°F (-40°C to +125°C)
• Industry Compliance: Meets SAE 20R4 Class D2 and DIN 73411 Class A requirements (except for tolerances)

Designed as a direct replacement for upper radiator applications, this hose measures approximately 2" x 2" x 20-29/32" and provides the same quality and reliability found in OEM installations. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing performance.

Note: Not for use in fuel or oil transfer applications. For coolant system use only.
