STEP 3.
Pressurize the cooling system to 3 psi (20 kPa) greater than the coolant fill cap
rating (13 to 16 psi (90 to 800 kPa)).
STEP 4.
Inspect all cooling system components for leaks. Repair or replace components
STEP 5.
Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to NORMAL.
On EMCP set Engine Control Switch to MANUAL START.
STEP 6.
Run the engine to operating temperature. If coolant temperature is normal,
proceed to step 17. If temperature is still too high, go to step 7.
STEP 7.
On EMCP set Engine Control Switch to OFF/RESET. Set Battery Disconnect
Switch to OFF. Set DEAD CRANK SWITCH to OFF.
STEP 8.
Allow generator set to cool and check coolant level. Add coolant as required.
STEP 9.
Check for presence of coolant in engine oil. If coolant is present in engine oil,
troubleshoot per SYMPTOM 33.
STEP 10.
Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to NORMAL.
On EMCP set Engine Control Switch to MANUAL START.
STEP 11.
Run the engine to operating temperature. If coolant temperature is normal,
proceed to step 17. If temperature is still too high, go to step 12.
STEP 12.
On EMCP set Engine Control Switch to OFF/RESET. Set Battery Disconnect
Switch to OFF. Set DEAD CRANK SWITCH to OFF.
STEP 13.
Allow generator set to cool and check coolant level. Add coolant as required.
STEP 14.
Pressurize the cooling system to 3 psi (20 kPa) greater than the coolant fill cap
rating (13 to 16 psi (90 to 800 kPa)).
STEP 15.
If pressure reading is not stable after five minutes, inspect all cooling system
components for leaks. Repair or replace components as required (WP 0063,
coolant temperature is normal, go to step 17. If coolant temperature is still too
high, repeat step 12 and then go to step 16.
STEP 16.
Pressurize the cooling system to 3 psi (20 kPa) greater than the coolant fill cap
rating (13 to 16 psi (90 to 800 kPa)). If pressure reading is not stable after five
minutes, replace the engine (WP 0098).
STEP 17.
Verify the problem has been resolved.
MALFUNCTION
Air in Coolant.
CORRECTIVE ACTION
STEP 1.
On EMCP set Engine Control Switch to OFF/RESET. Set Battery Disconnect
Switch to OFF. Set DEAD CRANK SWITCH to OFF.
STEP 2.
Inspect coolant fill cap for damage. Replace coolant fill cap as required.
