Dayco 88504 Molded Heater Hose with Quick Connect

The Dayco 88504 is a precision-molded small I.D. heater hose engineered to replace OEM coolant hoses and deliver reliable, long-lasting performance. This hose is manufactured with the same bends and routing as the original equipment assembly, ensuring a precise fit for specific vehicle applications.

Key Features:

• Pre-assembled quick connect end for fast, convenient installation without separate connectors or clamps
• Constructed from durable EPDM (ethylene propylene diene monomer) rubber compound for superior performance
• Knitted polyester reinforcement provides exceptional burst strength and resists degradation from temperature extremes and moisture
• Temperature range of -40°F to +257°F (-40°C to +125°C)
• Highly resistant to heat, ozone, coolants, and electro-chemical degradation
• Meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for quality assurance

The advanced EPDM construction resists the detrimental effects of environmental elements including road debris, while the Type EC electro-chemical resistance prevents inner tube deterioration caused by static electric charge buildup. This molded heater hose eliminates the hassle of purchasing and installing separate quick-connect fittings, making it a convenient direct-replacement solution for cooling system maintenance and repair.
