A-2. MAINTENANCE RECOMMENDATIONS
CAUTION: Never add coolant to an overheated engine; allow the engine to cool first.
Cooling
Check specific gravity of antifreeze solution frequently in cold weather to assure adequate
protection.
Coolant should be drained and replaced "Every 2000 Service Meter Units." With additions of Cooling
System Inhibitor or the use of Coolant Conditioner Elements as recommended, the drain period can
be extended to "Every 4000 Service Meter Units."
All water is corrosive at engine operating temperature. The cooling system should be protected with
inhibitor at all times regardless of concentration of antifreeze. This can be done by maintaining a
3% concentration of liquid Cooling System Inhibitor or by using Coolant Conditioner Elements.
Never use both the liquid cooling system inhibitor and coolant elements at the same time.
Do not use Cooling System Inhibitor or Coolant Conditioner Elements with Dowtherm 209 Full-Fill
Coolant.
Whenever draining and refilling cooling system, always recheck the coolant level when the engine
reaches normal operating temperature.
Filling at over 5 U.S. gallons (19 liters) per minute can cause air pockets in the cooling system.
Premix antifreeze solution to provide protection to the lowest expected ambient temperature. Pure
undiluted antifreeze will freeze at -100F (-23,)C).
Operate with a thermostat in the cooling system all year-round. Cooling system problems can arise
without a thermostat.
Electrical
CAUTION: When using jumper cables to start the engine, be sure to connect in parallel:
POSITIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-).
Scheduled Oil Sampling
Use scheduled Oil sampling to monitor the engine's condition and maintenance requirements. Each
oil sample should be taken when the oil is hot, and well mixed, to insure a sample which is representa
tive of the oil in the compartment.
Consult your engine dealer for complete information, and assistance in establishing a Scheduled Oil
Sampling program for your equipment.
