Gates 24293 Molded Coolant Hose

The Gates 24293 is a premium molded coolant hose engineered for reliable performance in automotive cooling systems. This pre-shaped curved hose is designed to fit upper, lower, bypass, heater, and other coolant applications with OEM-quality specifications, providing a precise fit and eliminating the need for trips to the dealer for replacement parts.

Key Features:

• Constructed from high-quality EPDM (ethylene propylene diene monomer) material with synthetic fiber knit reinforcement for superior durability
• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Heat and ozone resistant EPDM cover withstands extreme temperatures from -40°F to 275°F (-40°C to 135°C)
• Re-engineered materials resist vacuum collapse, reducing the need for internal springs in many applications
• Pre-shaped molded design ensures perfectly sealed connections and proper fitment
• Approved for marine applications
• Meets SAE 20R3 and 20R4 Type EC Class D-1 and D-2 specifications

Gates molded coolant hoses prevent electrochemical degradation by resisting the galvanic cell effect that occurs when the hose, liquid coolant, and metal fittings interact. This advanced engineering prevents micro-cracks from forming in the hose tube, extending service life and preventing roadside breakdowns. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance.
