Product Details

The Gates 51859 Premium Molded Coolant Hose is engineered to deliver OEM-quality performance for radiator, heater, and bypass coolant applications. This pre-shaped molded hose features 15/16-inch inlet and outlet diameters with a 6-7/8-inch centerline length, providing a precise fit for specific vehicle cooling system configurations.

Premium Construction Features:

  • EPDM tube with synthetic fiber knit reinforcement for superior durability
  • Heat and ozone-resistant EPDM cover withstands extreme temperatures
  • Engineered to resist electrochemical degradation (ECD), the leading cause of hose failure
  • Vacuum collapse resistance eliminates the need for internal springs in most applications
  • Pre-molded shape ensures properly sealed connections and easy installation

Performance Specifications:

  • Meets SAE 20R4 EC Class D1 requirements for premium coolant hose applications
  • Temperature range: -40°F to +275°F (-40°C to +135°C)
  • Resistant to heat, ozone, and modern chemical coolants including extended life formulations
  • Approved for automotive and marine applications

Gates molded coolant hoses are precision-manufactured to match OEM specifications, eliminating the need to visit dealerships for replacement parts. The premium EPDM compound resists the electrochemical degradation that occurs when coolant, metal fittings, and rubber hoses create a galvanic reaction, significantly extending service life and preventing costly breakdowns.

Note: Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure a secure, leak-free seal. Not intended for fuel or oil transfer applications.

I ordered a tire from thmotorsports that the manufacturer had discontinued two years earlier and which I could not find anywhere else, without checking customer reviews first, something I never do. Had I checked reviews first I would never have placed the order as the reviews I read after placing my order were uniformly awful. But rather than call and cancel the order, which was my first impulse, I resisted the urge to do so and waited. A day later, the shipping update said my tire had shipped, so I waited. Another day later, the shipping update said my tire would arrive a day later by the end of the day so I waited. On the appointed day, the tire, exactly the tire I had ordered and which was unavailable anywhere else, arrived at the end of the day, brand new, in perfect condition and I was utterly amazed. Thank you, thmotorsports, I am so glad I did not look at your reviews before placing my order.
