Dayco Heater Hose EPDM Construction

Dayco heater hose with EPDM construction carries hot coolant between the engine and the heater core in your vehicle's HVAC and cooling system. Dayco builds each hose as an OE replacement for passenger cars and light trucks. Use it to replace a cracked, soft, leaking or worn heater hose.

Key Features:

• All-EPDM rubber compounds: EPDM (ethylene propylene diene monomer) resists heat, ozone, weathering and aging.
• Spiral reinforcement: The reinforcement gives high burst strength. It also helps the hose resist kinking and collapse under vacuum.
• Coolant compatible: The hose is designed for use with all common coolants and coolant additives.
• Wide temperature range: Dayco's standard EPDM heater hoses are rated for roughly -40°F to +257°F (-40°C to +125°C).
• OE-style fit and function: The hose is built to match original-equipment performance and sizing for its application.

These hoses are for engine coolant service only. They are not suitable for fuel or oil transfer. Check heater hoses regularly as part of cooling system maintenance. Replace them at the first sign of cracking, swelling or leaks, so you avoid coolant loss and engine overheating.
