Cooling System Hoses/Clamps
HOSE CLAMPSDESCRIPTION - HOSE CLAMPS
The cooling system uses constant tension spring type hose clamps. If a spring type clamp replacement is necessary, replace with the original Mopar equipment spring type clamp.
Vehicles equipped with a 2.7L engine, use unique "Low Profile" type constant tension hose clamps at the coolant outlet connector hoses.
CAUTION: A number or letter is stamped into the tongue of constant tension clamps. If replacement is necessary, use only an original equipment clamp with matching number or letter (Fig. 22) or (Fig. 23).
OPERATION - HOSE CLAMPS
The constant tension type hose clamps maintain constant clamping force on the hose connections as the temperature of the cooling system rises and falls. Worm gear type hose clamps may not have sufficient
clamping force in colder weather conditions if installed during warm weather.
To remove a spring type hose clamp, use Special Tool 8495 Hose Clamp Pliers, or equivalent, (Fig. 24) to compress the hose clamp.
NOTE: Special Tool 8495 was specifically designed for use on the "Low Profile" type hose clamps used at the coolant outlet connector hoses on the 2.7L engine. The pliers are also compatible with other styles of constant tension type hose clamps.
