Product Details

The Dayco 71398 is a curved radiator coolant hose engineered for precise OE-replacement fitment in select import vehicles. Constructed from synthetic EPDM (ethylene propylene diene monomer) rubber with knitted reinforcement, this hose delivers reliable coolant flow and long-lasting durability in demanding engine cooling environments.

As a dual inside-diameter (Dual I.D.) hose, the 71398 features different end diameters — 1-5/16 inches on End 1 and 1-3/8 inches on End 2 — engineered to match the exact routing geometry of the original equipment cooling system without cutting or modification.

Key Features:

  • EPDM construction for excellent resistance to heat, ozone, coolant chemicals, and aging
  • Dual I.D. design — End 1: 1-5/16 in. / End 2: 1-3/8 in. inside diameter for precise OE fit
  • Trunk height: 15-1/2 inches for proper engine bay routing
  • Meets SAE J20R4 Class D-1 standards for radiator hose performance
  • Meets SAE J1684 Type EC electro-chemical requirements, preventing inner tube deterioration from static electric charge buildup
  • Black curved profile designed to follow OE coolant system routing without modification
  • Resists splitting, ballooning, and collapse under high-pressure and high-temperature conditions

Cross-references OEM part number Hyundai 25412-21200 and Duralast D71398. The Dayco 71398 is a direct-fit solution for restoring cooling system integrity and preventing overheating in compatible vehicles.

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!

Ordered a Thule hitch and was a little skeptical because I hadn't heard of this company. I was pleasantly surprised by the quickness of response when I ordered, I received an email immediately, and the order arrived just 2 days after it was ordered. This company goes to the top of my list.

Convient and simple. I found that is was one of the best price on line.
