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 generator set engine starting
battery(ies), negative (--) lead first.
1.4
When the engine has cooled, remove the
pressure cap and open the drain valve(s). See the
Service Views in the operation manual for drain
valve location.
1.5
Drain the coolant into a suitable container.
Note: Dispose of all waste materials (engine oil, fuel,
filters, etc.) in an environmentally safe manner
and in accordance with all applicable laws.
2.
Install the block heater.
Note: Apply pipe sealant to the threads of the hose
connectors.
2.1
Secure the block heater (352945 or 352946) to the
block heater bracket (GM32987) using 4 screws
(M933-06020-60), 4 washers (M125A-06-80),
and 4 hex nuts (M6923-06-80). See Figure 2.
2.2
Secure the block heater mounting bracket (with
the block heater attached) to the skid using
2 screws (M933-06020-60) and 2 hex nuts
(M6923-06-80). See Figure 2.
2.3
Remove the plug from the engine block and install
the adapter bushing (GM22991) and O-ring
(GM11694) as shown in Figure 2.
2.4
Install the street elbow (X-211-1) as shown in
Figure 2.

2.5
Install the hose connector (X-582-1) into the end
of the hose (X-312-24).
2.6
Install the hose/hose connector into the street
elbow as shown in Figure 2. Secure the hose to
the street elbow using a hose clamp (X-426-12).
2.7
Connect the other end of the hose (X-312-24) to
the block heater inlet. Secure the hose to the inlet
using a hose clamp (X-426-12).
2.8
Remove the pipe plug from the engine exhaust
manifold and install a bushing (153659), 2 street
elbows (227642), and hose connector (X-582-1).
See Figure 2.
2.9
Connect the hose (X-312-57) to the hose
connector installed in step 2.8. Secure the hose to
the street elbow using a hose clamp (X-426-12).
2.10 Connect the other end of the hose (X-312-57) to
the block heater outlet using a hose clamp
(X-426-12) to secure.
2.11 Loop the block heater cord and secure it with a
cable tie.
2.12 Close the drain valve(s) on the engine block.
2.13 Fill the cooling system. See the specification
sheet for cooling system capacities.
Note: Use a coolant solution of 50% ethylene glycol to
provide freezing protection to --37_C (--34_F) and
overheating protection to 129_C (265_F).
coolant solution with less than 50% ethylene
glycol can cause engine or component damage.
Do not use alcohol or methanol antifreeze or mix
them with the specified coolant.
Note: Do not add coolant to a hot engine. Wait until the
engine has cooled. Adding coolant to a hot
engine can cause the cylinder block or cylinder
head to crack.
