Corrective Action:
1. Check the engine coolant level and add coolant and repair leaks as necessary (p. 9-1, 12-1).
2. Check for and remove any objects blocking the air inlet or outlet openings in the bottom of the genset.
3. Reduce the number of appliances connected at the same time. (Note that high altitude and high ambient
temperature decrease engine cooling capacity.)
4. Look for a broken or worn coolant pump drive belt (p. 12-3) and replace as necessary (p. 12-1). (Visible
through the maintenance access door in the skid-base.)
5. Remove the air intake grille in the skid-base and check to see that the cooling blower (p. 11-1) is
secure and that the blades are not fouled.
6. Check for air leaks in the housing?missing or loose housing panels and access covers, including
the access covers for the fuses and AC terminals.
7. Clean and flush the cooling system to remove coolant passage fouling.
8. Remove the top housing panel (p. 6-4). If loose, reconnect engine harness spade terminal connector
E3-1 to the coolant temperature sender (p. 12-1, 19-1). (If the lead is loose and touching ground, the
controller will sense a high engine temperature.)
9. While the top housing panel is off (Step 8) , check for fouling of the radiator air passages and clear
out dust and debris with compressed air directed from below (reverse of normal air flow).
10. Replace the coolant thermostat (p. 12-1).
