Fig. 4, Breeze Constant-Torque Hose Clamp Installation
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.
11. Place a pan under the coolant filter to catch en-
gine coolant.
12. Remove the coolant filter with a strap or chain
wrench. Install a new coolant filter and tighten.
Columbia Maintenance Manual, January 2007
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
the coolant level is between the MIN and MAX
lines on the surge tank.
13. Fill the cooling system with new coolant. See

Table 1 for the vehicle's coolant capacity. Certain
equipment such as fuel heaters, water filters, and
auxiliary heaters may increase the coolant ca-
pacity and require additional coolant. The cooling
system is filled when the coolant level reaches
the MAX line on the surge tank. Freightliner rec-
ommends the use of a precharged and premixed
antifreeze when refilling the cooling system. See
Table 2 for a list of some of the precharged anti-
freeze available. Use of an equivalent antifreeze
to those listed in the table is also acceptable.
Always check that the antifreeze meets Freight-
liner's specifications and is at the proper concen-
tration for protection in the vehicle operating
area. See Table 3 for antifreeze protection infor-
mation. Freightliner specifies that antifreeze must
be an ethylene glycol solution that meets GM
6038 M Engineering Standards or a ethylene gly-
col solution that has less than 0.1% anhydrous
sodium metasilicate, and meets either GM 1825
M or GM 1899 M Engineering Standards. If
supplemental coolant additives are being used,
add the supplements to the coolant as neces-
sary. See the coolant additive manufacturer's
instructions for the correct amount of additive
required. Don't forget to consider the volume of
the supplemental coolant additive being added to
the system when determining the amount of
coolant required to refill the system.
