Gates 51388 Premium Molded Coolant Hose

The Gates 51388 Premium Molded Coolant Hose is a factory-molded radiator hose designed to provide OEM-quality performance for cooling system applications. This precision-engineered hose is pre-shaped to ensure a perfect fit and sealed connection in upper, lower, bypass, heater, and other coolant system positions.

Key Features:

• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• EPDM tube and cover construction with aramid or rayon knit reinforcement for superior strength and durability
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Heat and ozone resistant cover prevents premature cracking and deterioration
• Re-engineered materials resist vacuum collapse under engine operating conditions
• Pre-shaped design ensures proper fit and eliminates installation guesswork
• Marine application approved for use in harsh environments
• Meets or exceeds SAE specifications for automotive coolant hose

Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure optimal sealing performance. This hose is designed for coolant and water applications only and should not be used for fuel or oil transfer.
