What does a coolant bypass hose do?
It routes coolant through the bypass circuit so the engine warms evenly and maintains operating temperature. On these applications it runs at the rear from the intake manifold to the thermostat.
What is the hose made of?
It has an EPDM tube, synthetic fiber knit reinforcement, and a heat-, ozone- and chemical coolant-resistant EPDM cover. The materials also resist collapse under vacuum.
What are the temperature and spec ratings?
It meets SAE 20R4 class D2 and DIN 73411 class A requirements (except for tolerances) and is rated for -40°F to +257°F (-40°C to +125°C).
Should I replace the hose clamps too?
Gates recommends replacing the hose clamps each time a new coolant hose is installed. Do not use this hose for fuel or oil transfer applications.
