Continental 63081 Engine Coolant Bypass Hose

Continental 63081 is a molded engine coolant bypass hose built for direct routing in the vehicle cooling system. With a 0.750 in. inside diameter at both ends and a 6.906 in. hose length, it is sized for specific thermostat, pipe, valve, and heater connections across a wide range of applications.

Key Features

  • Molded coolant hose for bypass and radiator-system routing
  • 0.750 in. inside diameter at both ends
  • 6.906 in. overall hose length
  • Built for glycol-based coolant transfer through the cooling circuit
  • Meets or exceeds SAE 20R4EC Class D1 radiator hose specifications
  • Continental molded hose line for OE-style fitment

Product Details

Continental Molded part number 63081 is engineered for coolant flow between the radiator, thermostat housing, heater circuit, tee fittings, and related engine cooling components. The molded shape supports the routing required on many Toyota Highlander, Toyota RAV4, and Toyota Land Cruiser applications, along with select Chevrolet Express, GMC Savana, INFINITI, and other vehicle platforms. This part cross-references Gates 19670 for the same application.

As part of Continental’s Molded line, this hose is built for applications that require a formed coolant path rather than a straight universal hose. It is a direct replacement choice for vehicles using a 3/4-inch coolant connection and a compact molded profile.

Common Problems This Hose Can Address

  • Coolant leakage at a cracked or aged bypass hose
  • Softening, swelling, or collapse of the original hose
  • Improper coolant routing caused by a damaged molded hose
  • Overheating from restricted coolant circulation
  • Loss of heater or thermostat circuit flow due to hose failure

  • Fits 2011-2014 Toyota Highlander, Pipe To Thermostat
  • Fits 2012 Toyota RAV4, Thermostat To Pipe
  • Fits 2010 Toyota RAV4, Thermostat To Pipe
  • Fits 2011 Toyota RAV4, Thermostat To Pipe, U-Shaped Hose
  • Fits 1998-2007 Toyota Land Cruiser, Thermostat To Pipe-3
  • Fits 2011-2014 Chevrolet Express 1500, Pipe-2 To Valve
  • Fits 2005-2009 Chevrolet Express 1500, Valve To Pipe-2
  • Fits 2011-2014 GMC Savana 1500, Pipe-2 To Valve
  • Fits 2005-2009 GMC Savana 1500, Valve To Pipe-2

Verify the hose routing, molded shape, and connection diameters before installation. Match the existing coolant path on the vehicle, especially on applications listed as molded or cut-to-fit in the fitment data.

Quality Assurance

Continental manufactures this hose to meet or exceed SAE 20R4EC Class D1 radiator hose specifications, giving buyers a standards-based replacement for coolant system service. Continental 63081 is built for consistent fitment across the listed vehicle applications, including Toyota Highlander, Toyota RAV4, and Toyota Land Cruiser cooling system repairs.
