COOLING SYSTEM
COOLANT LEVEL
Check the coolant level in the radiator daily, only when
the engine is cool.
Maintain the coolant level at approximately 3/4 inches
(1.9 cm.) below the filler neck seat on the radiator
when the coolant is cold.
Whenever coolant level checks are made, check con-
dition of radiator cap rubber seal. Make sure it is clean
and free of any dirt particles. Rinse off with clean wa-
ter if necessary. When replacing cap on radiator, also
make sure radiator filler neck is clean.
WARNING
Never remove the radiator cap under any conditions while the engine is operating. Failure to follow
these instructions could result in damage to the cooling system or engine and/or personal injury. To
avoid having scalding hot coolant or steam blow out of the radiator, use extreme care when removing
the cap from a hot radiator, if possible, wait until the engine has cooled, then wrap a thick cloth
around the radiator cap and turn it slowly to the first stop. Step back while the pressure is released
from the cooling system. When you are sure all the pressure has been released, press down on the
cap (still with a cloth), turn and remove it. Do not add coolant to an engine that has become over-
heated until the engine cools. Adding coolant to an extremely hot engine can result in a cracked
block or cylinder head.
Use only a permanent type coolant that meets FORD specification ESE-M97B44-A such as FORD Cooling Sys-
tem Fluid. Refer to the coolant chart on the container for additional antifreeze protection information. Do not use
alcohol or methanol antifreeze, or mix them with the specified coolant. Plain water may be used in an emergency,
but replace it with the specified coolant as quickly as possible to avoid damage to the system. With only water in
the system, do not let engine run hot.
RADIATOR
Inspect the exterior of the radiator for obstructions. Remove all bugs, dirt or foreign material with a soft brush or
cloth. Use care to avoid damaging the fins. If available, use compressed air or a stream of water in the opposite
direction to normal airflow. Open door for access.
Check all hoses and connections for leaks. If any of the hoses are cracked, frayed, or feel spongy, they should be
replaced.
