7. Shut off the air at the pressure gun nozzle and
allow the radiator to refill with water.
8. Repeat the previous two steps until clean water
flows from the radiator.
9. Remove the radiator drain plug and allow the
radiator to drain. Install and tighten the drain plug
after the radiator has been drained. Do not
overtighten.
10. Connect the hoses using Breeze Constant-
Torque clamps See Fig. 2 .
When installing Breeze Constant-Torque hose
clamps, the clamps must be tightened to the
correct torque. The screw tip of the clamp must
extend about 1/4 inch (6 mm) from the clamp
housing, and the Belleville washer stacks must
be collapsed almost flat. Use a torque wrench to
install these clamps correctly. The correct
installation torque is as follows:
For Breeze Constant-Torque clamps with a 5/16-
inch tightening screw hex:
55 lbf·in (620 N·cm).
For Breeze Constant-Torque clamps with a 3/8-
inch tightening screw hex:
90 lbf·in (1020 N·cm).
NOTE: All hose clamps will lose torque after
installation due to "compression set." However,
when correctly installed, Breeze Constant-
Torque clamps will hold enough torque to
automatically adjust and keep consistent sealing
pressure. During vehicle operation and
shutdown, the screw tip may adjust according to
temperature and pressure changes. The torque
may need to be adjusted for individual
applications.
11. Refill the radiator with coolant.
12. Replace the surge tank cap(s).
13. Return the hood to the operating position.
14. Run the de-aeration procedure using
DiagnosticLink.
IMPORTANT: The approved coolant for
eCascadia is Extended Life Coolant (ELC) with
Organic Acid Technology (OAT) per Detroit Fluid
Specification (DFS) 93K217. For additional
information, see DDC-SVC-BRO-0002 on the
DTNA Connect Portal.
15. Shut off the vehicle, then check the coolant level
in the surge tank. Add coolant if the level isn’t at
the MAX line on the surge tank.
