The Gates YR33-8B274CA is a premium molded upper radiator coolant hose engineered to deliver OEM-quality performance and reliability. This precision-molded hose is constructed from high-quality EPDM (ethylene propylene diene monomer) rubber with synthetic fiber knit reinforcement, providing exceptional resistance to heat, ozone, and chemical coolant degradation.

Key Features:

• Pre-shaped molded design ensures perfect fit and sealed connections
• EPDM construction with synthetic fiber reinforcement for maximum durability
• Engineered to resist electrochemical degradation (ECD), the leading cause of hose failure
• Re-engineered materials resist vacuum collapse, reducing the need for internal springs
• Temperature range: -40°F to +257°F (-40°C to +125°C)
• Meets SAE 20R4 Class D-2 and DIN 73411 Class A specifications
• Centerline length: 27.8 inches with 1.47-inch inside diameter
