Coolant Line/Hose: Description and Operation
COOLING SYSTEM HOSES AND CLAMPS
Radiator lower hoses are spring-reinforced to prevent collapse from water pump suction at moderate and high engine speeds.
Inspect hoses at regular intervals. Replace hoses that are cracked, feel brittle when squeezed, or swell excessively when system is pressurized. The use
of molded replacement hoses is recommended. When performing a hose inspection, inspect radiator lower hose for proper position and condition of
spring.
Hose Clamp Tool-Typical
WARNING: CONSTANT TENSION HOSE CLAMPS ARE USED ON MOST COOLING SYSTEM HOSES. WHEN REMOVING OR
INSTALLING, USE ONLY TOOLS DESIGNED FOR SERVICING THIS TYPE OF CLAMP, SUCH AS SPECIAL CLAMP TOOL
(NUMBER 6094). SNAP-ON CLAMP TOOL (NUMBER HPC-20) MAY BE USED FOR LARGER CLAMPS. ALWAYS WEAR SAFETY
GLASSES WHEN SERVICING CONSTANT TENSION CLAMPS.
Clamp Number/Letter Location
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.
