Product Details

The Dayco 70397 is a precision-molded curved lower radiator hose designed to deliver reliable coolant flow in automotive cooling systems. This pre-formed hose features the exact bends and dimensions needed for a direct OE-fit replacement, eliminating the need for universal flexible hoses in applications where this part number is specified.

Key Features:

  • Durable EPDM (ethylene propylene diene monomer) rubber construction for superior heat and chemical resistance
  • Knitted reinforcement prevents splitting, ballooning, and elongation under pressure
  • Meets SAE J20R4 Class D-2 specifications for automotive coolant hose applications
  • Temperature range: -40°F to +257°F (-40°C to +125°C)
  • Resistant to ozone, coolants, and other detrimental environmental elements
  • Precision-molded curved design ensures proper fit and routing

Dayco coolant hoses are engineered to meet or exceed OE specifications, providing dependable performance in high-pressure, extreme-temperature cooling system environments. The curved lower radiator hose connects the bottom of the radiator to the engine's water pump inlet, playing a critical role in circulating coolant through the cooling system.

Its cool I guess

Prompt shipment, I got everything under 5 days even if part of my order was drop shipped (in stock items arrived in 2 days). Good communication, would do business again in a heartbeat.

No issues at all and a very good price to boot. What could be better? Will definitely order from them again.

So far so good. Easy transaction
