4. Drain the radiator, and flush the radiator until
clean water flows from the radiator. Remove the
flushing gun.
5. Close the petcock at the bottom of the radiator.
6. Connect the hoses. Your hose clamps can be
either T-bolt clamps (see Fig. 3) or Breeze
Constant-Torque clamps (see Fig. 4).
Tighten T-bolt type hose clamps 55 lbf·in (620
N·cm). These clamps are now standard on hoses
with an inside diameter greater than 2 inches (51
mm).
Breeze Constant-Torque hose 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.
Correct installation torque is as follows:
For Breeze Constant-Torque hose clamps with a
5/16-inch tightening screw hex:
55 lbf·in (620
N·cm).
For Breeze Constant-Torque hose 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 auto-
matically adjust and keep consistent sealing
pressure. During vehicle operation and shut-
down, the screw tip may adjust according to
temperature and pressure changes. The torque
may need to be adjusted for individual applica-
tions.
IMPORTANT: On vehicles with EPA07 compliant
engines, the coolant capacity varies depending
on the engine and accessory installation. After
servicing the cooling system, always verify that
