Gates Molded Coolant Hose is manufactured to fit specific applications.
It is similar to OEM specifications.
Approved for marine applications.
Recommended for upper, lower, by-pass, heater, and other coolant hose applications.
The cover is heat and ozone resistant.
Engineered to resist electrochemical degradation, which is the leading cause of hose failure.
The materials are re-engineered to resist vacuum collapse.
This reduces the need for internal springs in many applications.
It meets SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications.
The temperature rating is -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.
