5.4.3 Fuel Filter
The fuel filter is located on the generator set frame (see Figure 2.8 ).
To replace the fuel filter, loosen and remove the filter housing. Lightly oil new gasket with lube oil and replace the
filter.
NOTICE
If the generator set is equipped with the fuel filter bowl assembly, when replacing the fuel filter,
a new fuel filter O-ring should be oiled and replaced, and then the clear bowl should also be
tightened to 18 ft-lbs.
5.4.4 In-Line Fuel Strainer
Loosen bowl by turning counter-clockwise. To renew, remove in-line fuel strainer, check and clean, and replace.
5.4.5 Cooling System
To ensure adequate cooling, the radiator must be clean, externally and internally. To service the cooling system, do
the following:
1. Remove all foreign material from the radiator coil by reversing the normal air flow. Compressed air or water
may be used as a cleaning agent. It may be necessary to use warm water mixed with any good commercial
dishwasher detergent. If a detergent is used, rinse coil(s) with fresh water.
2. Drain coolant completely by opening drain cock and removing radiator cap.
CAUTION
!
Never pour cold water into a hot engine.
3. Close drain cock and fill system with clean, untreated water to which between 3% and 5% of an alkaline
base radiator cleaner should be added; six ounces (dry) = 151 grams to one gallon (3.8 liter) of water.
4. Run engine 6 to 12 hours and drain system while warm. Rinse system three times after it has cooled down.
Refill system with water.
CAUTION
!
Use only ethylene glycol, anti-freeze (with inhibitors) in system. Use of glycol by itself will dam-
age the cooling system (Refer to
Section 2.10 ).
5. Run engine to operating temperature. Drain system again and fill with treated water/anti-freeze (see above
Caution note).
