1.5.3 ENGINE OIL REQUIREMENTS

Use a high-quality detergent oil with American
Petroleum Institute (API) classification "For Service
CC." Detergent oils keep the engine cleaner and
reduce carbon deposits. Use oil having the following
SAE viscosity rating, based on the ambient tempera-
ture range anticipated before the next oil change:
Temperature
Above 100º F (38º C)
40º to 100º F (4.4º to 38º C)
Below 40º F (4.4º C)
Crankcase and oil filter capacity is approximately 3.5
L or 3.7 U.S. quarts. Do NOT use special additives.
See Sections 3.1 and 3.2 for oil level checking and
changing procedures.
◆

1.5.4 COOLANT

Use a 50:50 mixture that is half low silicate, ethylene
glycol base antifreeze and half soft water. Use only
soft water and only low silicate antifreeze. If desired,
a high-quality rust inhibitor to the recommended
coolant mixture may be added. When adding coolant,
always add the recommended 50-50 mixture.
DANGER
Do not remove the radiator pressure cap while
!
the engine is hot; otherwise, serious burns
from boiling liquid or steam could result.
Ethylene glycol base antifreeze is poisonous.
!
Do not use mouth to siphon coolant from the
radiator, recovery bottle, or any container.
Wash hands thoroughly after handling. Never
store used antifreeze in an open container
because animals are attracted to the smell and
taste of antifreeze, even though it is poisonous
to them.
Do not use any chromate base rust inhibitor
!
with ethylene glycol base antifreeze; or else,
chromium hydroxide ("green slime") will form
and cause overheating. Engines that have been
operated with a chromate base rust inhibitor
must be chemically cleaned before adding eth-
ylene glycol base antifreeze. Using any high-sil-
icate antifreeze boosters or additives will also
cause overheating. DO NOT use any soluble oil
inhibitor for this equipment.
