Gates 22190 Premium Molded Coolant Radiator Hose

The Gates 22190 Premium Molded Coolant Hose is engineered to deliver OEM-quality performance for upper, lower, bypass, heater, and other coolant system applications. This pre-shaped radiator hose is designed to fit specific vehicle applications while ensuring perfectly sealed conditions for reliable cooling system operation.

Advanced Construction and Materials:

• EPDM (Ethylene Propylene Diene Monomer) tube construction for superior durability
• Synthetic fiber knit reinforcement provides high burst strength
• Heat-, ozone-, and chemical coolant-resistant EPDM cover
• Specifically-engineered materials resist vacuum collapse, reducing the need for internal springs
• Pre-shaped design ensures proper fit and sealed connections

Key Performance Features:

• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Operates reliably in extreme temperatures from -40°F to +257°F (-40°C to +125°C)
• Meets or exceeds SAE 20R4 Class D2 and DIN 73411 Class A specifications
• Approved for marine applications for versatile use
• Comprehensive coverage as part of Gates' most complete molded hose line on the aftermarket

Gates coolant hoses are manufactured with the same quality standards used for OEM production vehicles, providing a cost-effective alternative to dealer replacement parts. The advanced EPDM compound resists the electrochemical reactions that can form micro-cracks in inferior hoses, ensuring longer service life and preventing costly breakdowns.

Installation Note: Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure proper seal and system integrity.
