Engine Cooling System - Hobart 60CU24 Operation And Maintenance Manual With Illustrated Parts List

OM-2098C / Operation and Maintenance Manual
60CU24 / Series 500060C / 400 Hz. Generator Set
i Fill new filter with diesel fuel
Screw in the new fuel filter "snug". Check that the cartridge is seated correctly against the
gasket and tighten with a final half turn.
j Open fuel valve.
e) Fuel Return
The fuel return is a fuel line (tube) that takes unused fuel from the engine, and delivers it to the fuel
tank. No maintenance is required.
f) Priming Fuel System (when applicable)
If this generator set has been run out of fuel, the fuel system must be manually primed with diesel fuel
up to the fuel water separator before the generator set can be started again. See Paragraph 5 for
instructions for priming the fuel water separator system. Once the fuel has reached the fuel water
separator, close all open valves (i.e. filter vent plug) and cranked the engine until the fuel reaches the
injectors and the engine starts.
CAUTION
Make sure that all rags, or absorbent sheets, are clear of moving engine parts and
cannot be drawn in to the radiator fan.
CAUTION
Do not crank the engine for more then 15 seconds continuously. Allow the starter to
cool for 15 seconds between attempts.

6) Engine Cooling System

a) General
Cooling system service requires more than maintaining the proper coolant level in the radiator and
protecting the system against freezing. Water should by clean and free of any corrosive chemicals
such as chloride, sulfate, and acids. It should be kept slightly alkaline with a pH value in the range of
8.0 to 9.5. Any water, which is suitable for drinking, can be used in the engine when properly treated
as described in engine manufacturer's operation manual. The engine manufacturer's representative
should be consulted regarding the selection of satisfactory brand, permanent-type antifreeze for use
in the cooling system.
b) Radiator Cap
(1) General
A pressure relief valve is built into the radiator cap. It is designed to open at a pressure of
approximately 10 psi (68.9 Kpa).
WARNING
When removing cap from a very hot radiator, do not turn cap past safety stop until the
pressure or steam has escaped.
