Product Details

The Dayco 71243 is a curved, lower radiator coolant hose engineered to deliver reliable engine cooling performance. Built from synthetic EPDM rubber with knitted reinforcement, this hose resists degradation from ozone, coolants, coolant additives, and extreme temperature cycles — keeping your cooling system sealed and operating efficiently.

This is a Dual I.D. hose, featuring a 1-1/2" inside diameter on one end and a 1-3/4" inside diameter on the other, with a trunk height of 15-3/4". This dual-diameter design ensures a precise, leak-free fit at both the engine and radiator connection points without the need for adapters.

Key Features:

  • Material: Synthetic EPDM rubber with knitted reinforcement for high-strength performance
  • Hose Type: Dual I.D. curved radiator hose
  • End 1 Inside Diameter: 1-1/2"
  • End 2 Inside Diameter: 1-3/4"
  • Trunk Height: 15-3/4"
  • SAE Specifications: SAE J20R4 Class D-1 and SAE J1684 Type EC
  • Color: Black
  • Cross-references: 22190M, 24191L

Dayco coolant hoses are designed to meet or exceed OE specifications and all relevant SAE standards, providing confidence that this hose will perform to the same standards as the original equipment it replaces.

Sold individually.

The best price on what I was looking for and fairly fast to get it shipped out considering it was drop shipped directly from the manufacturer. Autoplicity has a huge selection and I will definitely be back when ever I need other automotive parts.

Received my package today. Shipping was fast and it was about the best price I could find for my Cam. I'll buy from them again.

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.

I will definitely do more shopping with Autoplicity....great prices and quick shipments.

Helpful-reasonable prices-reasonable shipping-prompt.

Quick and easy. Plus a great deal can't be beat
