Product Details

The Dayco 71964 is a precision-molded curved lower radiator hose engineered for reliable coolant transfer in automotive cooling systems. This OEM-quality replacement hose is designed to provide an exact fit with no cutting or modifications required, ensuring proper coolant flow and system performance.

Construction and Materials:

  • EPDM (Ethylene Propylene Diene Monomer) rubber construction for superior durability
  • Knitted rayon fiber reinforcement for maximum burst strength and collapse resistance
  • Heat-resistant cover rated from -40°F to +257°F (-40°C to +125°C)
  • Resistant to oil, grease, ozone, coolants, and all approved coolant additives

Performance Features:

  • Meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
  • Type EC electro-chemical compliance prevents premature inner tube deterioration
  • Curved molded design ensures proper routing and connection points
  • Tested for static pressure, dynamic pressure, burst resistance, and temperature extremes
  • Lower position installation for optimal cooling system operation

This precision-engineered hose is manufactured to OEM standards and is designed to replace worn, cracked, or damaged original equipment hoses. Dayco recommends replacing hose clamps when installing any new coolant hose. Not suitable for fuel or oil transfer applications.

Effin Awesome!!

So far so good haven't got it in the mail yet

Quick and easy checkout

I bought from them for the first time because the price was the lowest listed on Amazon. They shipped it fast and I am happy. I will buy again.

Cheapest prices i could find, and answered all the questions i had. Very fast shipping

Quick and easy!

I was greatly surprised at how soon I received my order, 3 day early!! I will definitely look here the next time I need parts.

Great prices for the parts I needed to replace on my SUV, a bit hard to reach customer service when I had a question about the order. When I finally did reach CS, question was answered without any issues, shipping costs seem a bit high.

So far so good!
