Product Details

The Dayco 87834 is a molded OE replacement heater hose designed for the reservoir-to-pipe connection in your vehicle's coolant system. Built with EPDM rubber construction and spiral reinforcement, this hose delivers high burst strength and exceptional heat resistance to keep your cooling and cabin heating system operating reliably.

Key Features:

  • EPDM compound construction provides excellent resistance to heat, ozone, and weathering
  • Spiral reinforcement for high burst strength and long-term durability
  • Temperature rated from -40°F (-40°C) to +257°F (+125°C) for year-round reliability
  • Compatible with all common coolants and coolant additives, including modern OAT and HOAT formulations
  • Molded to OE specifications — same bends and routing as the original assembly for a precise, no-modification fit
  • Meets SAE J20R3, Class D-2 standard construction requirements
  • Sold individually

The Dayco 87834 heater hose is a direct-fit OE replacement that restores proper coolant flow between the reservoir and pipe, helping prevent coolant leaks and maintaining efficient cabin heat. Engineered to Dayco's exacting standards, this hose is a reliable, long-lasting solution for maintaining your vehicle's HVAC 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.

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

Went to ebay, amazon, and summit racing looking for this part and finally found it here after looking on this site for about 10 seconds.

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.
