3.3.5 Adding Engine Coolant.
a.
Park the paving machine on level ground. Shut
off the engine per paragraph 2.11. After the
engine stops, place the ignition switch (1) to the
ON position.
b.
Check coolant temperature gauge (2) on gauge
panel J until water temperature cools to 120°F
(49°C). Place ignition switch to the STOP
position.
c. Open front top left access door per paragraph
2.24.1.
Extreme care should be taken when
removing radiator cap if temperature
gauge reads above 180°F (82°C).
Contact by steam or hot coolant may
result in injury or death to personnel
Use a clean, thick, waste cloth or like
material to remove the cap. Avoid
using gloves. If hot water soaks
through gloves, personnel could be
burned.
Use extreme care when removing the
radiator pressure cap. Sudden
release of pressure can cause a
steam flash which could seriously
injure personnel.
d.
Use a cleaning cloth (Item 1, Appendix D) to
slowly loosen radiator cap (3) to the first stop to
release pressure.
e.
After pressure is released, remove radiator cap
(3).
f.
Visually check engine coolant level. Proper
coolant level is below filler neck and above the
radiator fins.
CAUTION
A 50:50 ratio of antifreeze to water
mixture must be premixed before
adding coolant to the radiator. The
ability of antifreeze to remove heat
from the engine is not as good as
water. Pouring antifreeze into the
engine
first
could
cause
an
overheated
condition
before
the
liquids are completely mixed.
g.
Mix the required amount of 50:50 ratio of
antifreeze (Item 2, Appendix D) to water mixture
and fill radiator to proper level.
h.
Replace radiator cap (3) and tighten.
i.
Close front top left access door per paragraph
2.24.2.
