Molded Coolant Hose Gates Molded Coolant Hose is Manufactured to Fit Specific 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 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 SB Clamps each time a new coolant hose is installed. Caution: Do not use for fuel or oil transfer applications
