GENERAL MAINTENANCE INFORMATION
The following section outlines some aspects of general maintenance which will be of value to the
operator.
Cooling System
To obtain maximum engine service life, its operating temperature must be maintained by an
efficient cooling system.
CAUTION: Under no circumstances should the engine be started without liquid
in the cooling system. This may cause permanent damage to the engine.
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 low pressure compressed air or a stream of
water in the opposite direction to normal airflow. Check all hoses and connections for leaks. If any
of the hoses are cracked, frayed, or feel spongy, they should be replaced.
CAUTION: Never use a cold coolant mixture to top-up the radiator or degas tank of a hot
engine if the coolant level is very low; this could cause serious engine damage.
The radiator or degas tank is equipped with a pressure cap. It is dangerous to
remove this when the system is very hot.
WARNING: NEVER REMOVE THE PRESSURE RELIEF CAP WHILE THE ENGINE IS
OPERATING OR WHEN THE COOLING SYSTEM IS HOT. MAY CAUSE PERSONAL INJURY
OR DAMAGE TO COOLING SYSTEM OR ENGINE. TO REDUCE THE RISK OF HAVING
SCALDING HOT COOLANT OR STEAM BLOW OUT OF THE DEGAS BOTTLE WHEN
REMOVING THE PRESSURE RELIEF CAP, WAIT UNTIL THE ENGINE HAS COOLED DOWN
TO AT LEAST 40°C (110°F).
1. Wrap a thick cloth around the pressure relief cap and turn it slowly one-half turn
counterclockwise. Stepping back while the pressure is released from the cooling system.
2. When you are sure all the pressure has been released, (still with a cloth) turn counterclockwise
and remove the pressure relief cap.
In territories where freezing conditions may occur, the coolant should consist of a mixture of 50%
plain water and 50% Motorcraft Super Plus 2000 coolant. This
antifreeze contains additional corrosion inhibitors designed to provide lasting protection for the
engine.
Only this antifreeze, or proprietary antifreeze meeting Ford specification WSSM97B44-
D or Ford specification ESE-M97B44-A should be used when topping-up or re-filling the cooling
system.
Motorcraft Super Plus 2000 coolant has long life characteristics and if the concentration is kept to a
maximum of 50% it will provide adequate frost protection and inhibiting for the life of the engine.
