Gates Molded Coolant Hose is manufactured to fit specific applications. Similar to OEM specifications. Approved for marine applications.

  • Recommend for upper, lower, by-pass, heater and other coolant hose applications.
  • Heat and ozone resistant cover.
  • Engineered to resist electrochemical degradation - the leading cause of hose failure.
  • Re-engineered materials resist vacuum collapse. This reduces the need for internal springs in many applications.
  • Meets SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications.

Temperature Rating: -40° F to 275° F (-40° C to 135° C) in coolant hose applications.

Note: Gates recommends replacing standard worm drive and spring loaded clamps with Gates PowerGrip(R) SB Clamps each time a new coolant hose is installed.
