Cooling System Filling
STANDARD PROCEDURE - FILLING COOLING SYSTEMCAUTION: Do not use well water, or suspect water supply in cooling system. A 50/50 mixture of the recommended ethylene glycol and distilled water is recommended.
NOTE: For cooling system capacity, Refer to specifications.
1. Close radiator draincock. Hand tighten only.
2. Open, but do not remove cooling system bleed valve.
3. Attach a 6.35 mm (0.250 in.) inside diameter clear hose that is 120.0 cm (48 in.) long to the bleed valve. Route the hose away from the accessory drive belts and radiator fan. Position the other end of the hose into a collecting container. The hose will prevent coolant from contacting the accessory drive belts, A/C compressor, and other components.
NOTE: Be careful not to spill coolant on drive belts or the generator.
4. With the pressure cap removed, slowly fill the cooling system until a steady stream of coolant flows from the attached hose on the bleed valve.
6. Close the bleed valve and remove the hose.
6. Fill coolant to the top of the pressure cap neck.
7. Install cooling system pressure cap.
8. Slowly fill coolant reserve/recovery bottle to at least the FULL HOT mark with the recommended coolant. It may be necessary to add additional coolant to the reserve/recovery bottle after three or four warm-up/cool down cycles to maintain coolant level between the FULL HOT and ADD marks. This is due to the removal of trapped air from the system.
