Product Details

The Dayco 71577 is a precision-molded curved radiator hose designed to provide a reliable, direct-fit replacement for OEM coolant hoses. Engineered with EPDM (ethylene propylene diene monomer) rubber construction and knitted reinforcement, this hose delivers exceptional durability and resistance to the harsh conditions found in modern cooling systems.

Key Features:

  • EPDM rubber construction for superior resistance to coolant, ozone, and environmental degradation
  • Knitted reinforcement provides strength and prevents splitting or ballooning under pressure
  • Pre-formed curved design ensures proper routing and OE-quality fit
  • Meets SAE J20R4 Class D-2 specifications for automotive coolant hoses
  • Withstands temperature extremes from -40°F to +257°F (-40°C to +125°C)
  • Black finish for a clean, professional appearance

This molded radiator hose is designed as a direct replacement for multiple OEM part numbers including GM 21030220, 21031478, 21030815, 21031147, and 21031248. Cross-references with Gates 21946, ACDelco 20261S, NAPA 3L260, and Duralast B71577. Dayco's precision manufacturing ensures this curved hose provides the exact fitment and performance of the original equipment part at a competitive price.

Very good value and received my shipment in a very timely matter

Autoplicity has a wide selection of parts and great prices. Fast shipping and great customer service.

After having trouble completing the payment process through Amazon, I was able to complete my payment information directly on the Autoplicty website and submit the order quickly. The process was easy and fast. They had the best overall price (item plus shipping) I could find on the net. The item was shipped promptly and arrived in great condition. A quality merchant all the way around.

Autoplicity is awesome! Easy check out and quick shipping! Will buy from again!

Had a great first experience with Autoplicity. I ordered my package late in the day on Wednesday and it was at the front door Thursday! Another big plus is that their prices are hard to beat. Won't have a problem ordering from them again!

very cheap prices compared to competitors hoping product is as good as price.

I like the service and cheap price i will recommend autoplicity.
