Dayco 72436 Curved Radiator Hose, Dual I.D. EPDM Coolant Hose

The Dayco 72436 curved radiator hose (also called a radiator coolant hose) is a molded replacement hose that carries coolant between the engine and the radiator. Its pre-formed curved shape follows the original routing, so it installs without kinking.

Key Features:

• Dual I.D. design: one end has a 1 17/32 in inside diameter (1 29/32 in outside diameter) and the other end has a 1 19/32 in inside diameter (2 in outside diameter)
• Trunk height of 17 in
• Black EPDM rubber construction resists ozone, coolants and temperature swings from -40°F to +257°F (-40°C to +125°C)
• Knitted rayon reinforcement in the inner tube adds burst strength
• Meets SAE J20R4 Class D-1 and SAE J1684 Type EC. Type EC helps prevent inner tube damage from static electric buildup
• No protective sleeve or heat shield

This hose is a direct-fit replacement for a cracked, swollen or leaking original. For best results, replace the hose clamps and refill with fresh coolant when you install it.
