Molded Heater Hose
Modular hoses are on many of today's vehicles and are much more complex than the standard molded hoses of the past. Manufactured identical or equivalent to the OE hose, modular coolant hoses will keep your vehicle's cooling system running properly and efficiently for years to come.

Features & Benefits:
  • Engineered to resist electrochemical degradation (ECD®) – the leading cause of hose failure.
  • Eliminates water loss due to permeation.
  • Recommended for upper, lower, by-pass, heater and other coolant hose applications.
  • Heat and ozone resistant cover.
  • Installs easily without buckling, bending out of shape, or straining at connections.
  • Temperature rating: -40°F to 275°F (-40°C to 135°C) in coolant hose applications
  • Meets SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications.
Gates recommends replacing standard worm drive and spring loaded clamps with PowerGrip® SB clamps each time a new coolant hose is installed. Do not use for fuel or oil transfer applications.
