Gates 23786 Premium Molded Lower Radiator Coolant Hose

The Gates 23786 Premium Molded Coolant Hose is a pre-shaped lower radiator hose engineered to deliver OEM-quality performance and reliability. This molded coolant hose is specifically designed to resist electrochemical degradation (ECD), the leading cause of coolant hose failure that occurs when the hose, liquid coolant, and engine fittings form a galvanic cell.

Advanced Engineering Features:

• EPDM tube construction with synthetic fiber knit reinforcement for superior strength
• Heat-, ozone-, and chemical coolant-resistant EPDM cover
• Re-engineered materials resist vacuum collapse, reducing the need for internal springs
• Pre-shaped design ensures perfect fit and properly sealed connections
• Temperature range: -40°F to +257°F (-40°C to +125°C)

Meets Industry Standards:

• SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications
• SAE 20R4 Class D2 and DIN 73411 Class A compliance

Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance and leak prevention. This hose is manufactured to OEM-quality specifications, providing a cost-effective alternative to dealership parts without sacrificing quality or fit. Not intended for fuel or oil transfer applications.
