Engine Maintenance

Install Coolant Fill Tube Assembly (T-Series Shown, UT-Series Similar)
b. Lock HMI to read engine coolant temperature (if Standard HMI a service tool should be used).
c.
As the coolant temperature increases, air bubbles will escape through the coolant fill tube as the thermostat begins to
open (approximately 72°C).
d. Allow the engine to run on high speed at a stabilized coolant temperature of approximately 85°C until the air bubbles
cease to come out of the coolant. Note to achieve a coolant temperature of 85°C it will be necessary to cover the
condenser coil from the bottom edging up slowly thereby increasing the coolant temperature and fully opening the
thermostat.
e.
As air escapes from the cooling system the coolant level in the fill tube will decrease. Should the coolant level drop
down so it is no longer visible, add additional coolant at the top of the fill tube. Continue this step until the air bubbles
stop expelling out through the fill tube.
f.
Intermittently, check the head pressure on the HMI to ensure the pressure does not become excessively high potentially
causing the unit to shuT-down.
g. Repeat Steps as required until the coolant level in the fill tube remains constant i.e. no more air bubbles in the fill tube.
h. Then squeeze/clamp the expansion tank to thermostat coolant hose to force more coolant flow through the radiator.
This will likely lower the temperature of the coolant so the coverage of the condenser coil will need to be increased to
maintain the coolant temperature of approximately 85°C.
i.
With the flow through the radiator now maximized, repeat Steps d and e.
j.
Continue running the coolant loop under these conditions until the coolant is free of all entrained and / or entrapped air.
k. Remove the cover placed over the condenser coil first and then three minutes later unclamp the expansion tank to
thermostat coolant hose.
l.
Continue running the coolant loop until the coolant stabilizes at approximately72°C.
m. Shut off engine and allow system to cool down to the ambient temperature
n. Remove the fill hardware and check the level of the coolant (expansion tank should be completely full).
o. Ensure the coolant level in the overflow tank is adequate.
4. Replace the expansion cap.
