Fuel Filter

The fuel filter is located on the generator set unidrive assembly (see
and remove the filter housing. Lightly oil new gasket with lube oil and replace the filter.
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.

In-Line Fuel Strainer (Option)

Loosen bowl by turning counter-clockwise. To renew, remove in-line fuel strainer, check and clean, and replace.
5.5.5

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. Rinse coil(s) with fresh water if a detergent is used.
2. Drain coolant completely by opening drain-cock and removing radiator cap.
3. Close drain-cock and fill system with clean, untreated water to which three to five percent 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.
Use only ethylene glycol (anti-freeze with inhibitors) in system. Use of glycol by itself will dam-
age the cooling system. (Refer to
