ENGINE COOLANT

Engine Coolant Specifications

• Texaco Long Life Coolant (LLC), both
• Havoline Extended Life
Note: In the U.S., LLC is required for the
warranty to be valid.
NOTICE: Following the manufacturer's
recommendations, use a proper LLC
which will not have any adverse effects
on the materials (cast iron, aluminum,
copper, etc.) of the engine's cooling
system. See Engine Coolant
Specifications on page 33.
ALWAYS use the mixing ratios specified by
the antifreeze manufacturer for the
0004912
temperature range.
NOTICE: ALWAYS add LLC to soft water
– especially when operating in cold
weather. NEVER use hard water. Water
should be clean and free from sludge or
particles. Without LLC, cooling
performance will decrease due to scale
and rust in the coolant system. Water
alone may freeze and form ice; it
expands approximately 9% in volume.
Use the proper amount of coolant
concentrate for the ambient
®
Bravo Stern
temperature as specified by the LLC
manufacturer. LLC concentration
should be a minimum of 30% to a
maximum of 60%. Too much LLC will
decrease the cooling efficiency.
Excessive use of antifreeze also lowers
the cooling efficiency of the engine.
NEVER mix different types or brands of
LLC, as a harmful sludge may form.
Mixing different brands of antifreeze
may cause chemical reactions, and may
make the antifreeze useless or cause
engine problems.
