Product Details

The Dayco 87643 is a standard OE-replacement heater hose designed to carry heated coolant from the heater core to the water pump. Built with all-EPDM (Ethylene Propylene Diene Monomer) compounds and spiral reinforcement, this hose delivers high burst strength and reliable heat resistance for long-lasting cooling system performance.

Key Features:

  • All-EPDM construction provides excellent resistance to heat, ozone, and common coolant chemicals
  • Spiral reinforcement ensures high burst strength and dimensional stability under pressure
  • Compatible with all common coolants and coolant additives, including OAT, HOAT, and conventional formulas
  • Temperature rated from -40°F (-40°C) to +257°F (+125°C) — similar to SAE 20R3, Class D-2 standards
  • Direct OE replacement — engineered to match original equipment routing and dimensions
  • Sold individually

Dayco heater hoses are designed to meet or exceed OE specifications and relevant SAE standards, making the 87643 a dependable choice for restoring proper coolant flow in your vehicle's heating and cooling system.

Purchased my mishimoto heat tape. Cheapest price around and the shipment was delivered in a very reasonable time. Couldnt be happier

Best price on the internet for my parts. Shipped out the next morning.

Very fast shipping, always great prices.

shipped fast, cant wait to put it on the jeep, would buy from here in the future.

Absolute lowest price on the web. Correspondance was great letting me know every step of the purchase and shipping process right up to a tracking number.<br>Ordered Tue. got tracking number Friday ... great job great savings.<br><br>I highly recommend doing business with this fine company!!

I'll admit to being skeptical at first, but the price was worth the risk. Turned out to be one of the best online transactions I've experienced. Received item 3 days after purchaseing and the best price I found. And I looked hard! A+

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.
