HOSE CLAMPS
DESCRIPTION
The cooling system utilizes both worm drive and
spring type hose clamps. If a spring type clamp
replacement is necessary, replace with the original
Mopar equipment spring type clamp. To identify
size of spring hose clamps, the size in millimeters
has been stamped on each clamp (Fig. 13). Refer to
HOSE CLAMP USAGE CHART for proper size and
location of hose clamps.

OPERATION
The worm type hose clamp uses a specified torque
value to maintain proper tension on a hose connection.
The spring type hose clamp applies constant ten-
sion on a hose connection. To remove a spring type
hose clamp, use Special Tool 6094 or equivalent, con-
stant tension clamp pliers (Fig. 14) to compress the
hose clamp.
