Read the entire installation procedure and compare the
kit parts with the parts list at the end of this publication
before beginning installation. Perform the steps in the
order shown.
Safety Precautions
Observe the following safety precautions while installing
the kit.
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (--) lead first
when disconnecting the battery.
Reconnect the negative (--) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or equipment connected to the set, disable the
generator set as follows: (1) Press the generator set off/reset
button to shut down the generator set. (2) Disconnect the
power to the battery charger, if equipped. (3) Remove the
battery cables, negative (--) lead first. Reconnect the negative
(--) lead last when reconnecting the battery. Follow these
precautions to prevent the starting of the generator set by the
remote start/stop switch.
Hot coolant and steam.
Can cause severe injury or death.
Before removing the pressure cap,
stop the generator set and allow it to
cool. Then loosen the pressure cap
to relieve pressure.
WARNING
Allow the engine to cool. Release pressure from the
cooling system before removing the pressure cap. To
release pressure, cover the pressure cap with a thick
cloth and then slowly turn the cap counterclockwise to
the first stop. Remove the cap after pressure has been
completely released and the engine has cooled. Check
the coolant level at the tank if the generator set has a
coolant recovery tank.

Installation Procedure
1. Remove the generator set from service.
1.1 Press the generator set OFF/RESET button to
shut down the generator set.
1.2 Disconnect the power to the battery charger, if
equipped.
1.3 Disconnect the power to the block heater, if
equipped.
1.4 Disconnect the generator set engine starting
battery(ies), negative (--) lead first.
1.5 Remove the coolant drain plug and allow the
coolant to drain completely. See Figure 3 for
coolant drain plug location.
Remove the pressure cap to allow the entire
system to drain and prevent air pockets from
restricting coolant flow through the engine block.
Note: Dispose of all waste materials (engine oil,
fuel, filter, etc.) in an environmentally safe
manner and in accordance with all
applicable laws.
2. Remove the belt guard, coolant recovery
tank, and dry exhaust elbow.
2.1 Remove the belt guard, belt guard brackets,
coolant recovery tank and bracket, and hose that
connects to the pressure cap. See Figure 3.
2.2 Remove the dry exhaust elbow. Save the clamp
SeeFigure3.
2.3 Install the new dry exhaust elbow (GM49740)
using the existing clamp.
3. Disconnect the low seawater pressure
switch.
3.1 Disconnect the lead to the low seawater pressure
switch. Tape the bare lead and tie it back into the
engine harness. See Figure 4.

12. Restore the generator set to service.
12.1 Replenish the coolant. See the generator set
specification sheet for radiator cooling capacities.
See the generator set operation manual for the
coolant fill procedure.
12.2 Check that the generator set is OFF.
12.3 Reconnect the generator set engine starting
battery, negative (--) lead last.
12.4 Reconnect power to the battery charger, if
equipped.
12.5 Test run the generator for a few minutes to check
for leaks. Shut off the generator set and allow it to
cool. Check the coolant level to ensure that all air
is purged from the system. Add coolant as
necessary to fill the system.
Note: Engine damage. Failure to bleed the air
from the cooling system may cause
overheating and subsequent damage to
the engine.
Note: Block Heater Damage. The block heater
will fail if the energized heater element is
not immersed in coolant. Fill the cooling
system before turning on the block heater.
Run the engine until it is warm, and refill
the radiator to purge the air from the
system before energizing the block heater.
12.6 Reconnect power to the block heater, if equipped.
13. Disable the high exhaust temperature
shutdown.
13.1 Using SiteTecht, under the Programmable
Digital Input 112 parameter, disable the settings
to the following:
Digital Input Enabled: Off
Digital Input Logic: Active Close
Figure 16 Programmable Digital Input 112 Parameter
(in SiteTecht)
Note: For more information on SiteTecht,see
TP-6701tSiteTech Software Operation Manual.
14. Disable the low seawater pressure
shutdown.
