equipped with a fresh water cooling
system is 170° F and if equipped with
a raw water cooling system, 140° F.
Normal operating temperature for diesel
engines is between 170° F and 190° F.
Check for water discharging from the
exhaust outlets. The presence of water
indicates water circulation in the exhaust
cooling system. Water should discharge
through the exhaust outlets immediately
after the engine starts.
After engines reach their normal oper-
ating temperature, increase the RPM’s
to 2000. Be certain the voltmeters read
between 13 and 14.5 volts.
Visually inspect the exhaust system for
leaks. If any leaks are detected, imme-
diately turn OFF the respective engine
and contact a competent technician for
repair.
Check the transmission fl uid level after
the engine is warm. The transmission
should be in neutral and the engines
operating at idle speed. Transmission
fl uid should be at or slightly below the
FULL mark on the dipstick. Add trans-
mission fl uid if the level is low, but DO
NOT overfi ll.
Shakedown Cruise
Silverton recommends a shakedown cruise
after the initial or seasonal startup. This will
test the engines and various systems under
normal operating conditions. Note any con-
dition that does not meet normal operating
performance standards. Repair any condi-
tion noted as soon as possible.
