b. Thermostat Installation
1. Install the engine thermostat, thermostat gasket and
thermostat housing. Secure with the two capscrews.
Torque to 24 Nm (18 lb-ft).
2. Connect the battery negative (-) cable to the battery
negative (-) terminal.
3. Open the radiator cap, and fill the radiator
completely with a 50/50 mixture of ethylene glycol
and water. Replace and tighten the radiator cap. Add
coolant to the overflow bottle until the bottle is 1/4 to
1/2 full. This overfilling will compensate for any air
trapped in the cooling system.
4. Run the engine to operating temperature. Visually
check for leaks with the engine running. Check the
coolant level in the overflow bottle and fill, or drain,
as necessary.
5. Close and secure the engine cover.
7.4.3
Radiator/Oil Cooler and Coolant
Heater Replacement
Before considering radiator or oil cooler replacement for
other than obvious damage, conduct a cooling system
pressure test check the coolant specific gravity, coolant
level, fan belt tension and dash panel temperature
indicator.
• If the engine runs hot, check the temperature of
the upper radiator hose.
• If the hose is not hot, the thermostat may be
stuck in the closed position.
• If the engine has overheated, performance may
suffer, indicating other damage including a leaking
cylinder head gasket, cracked cylinder head or
block, and/or other internal engine damage.
a. Radiator/Oil Cooler Removal
1. Park the machine on a firm, level surface, level the
machine, fully retract the boom, lower the boom,
place the transmission control lever in
(N) NEUTRAL, engage the park brake and shut the
engine OFF.
2. Place a Do Not Operate Tag on both the ignition key
switch and steering wheel, stating that the machine
should not be operated.
3. Open the engine cover. Allow the system fluids to
cool.
4. Disconnect the battery negative (-) cable from the
battery negative (-) terminal.
5. Remove the engine cover to ease removal of
radiator/oil cooler.
6. If necessary, remove the windshield washer fluid
reservoir.
7. On platform equipped 13M machines, remove the
ERS control panel and bracket to gain access to
radiator mounting points. Refer to Section 8.8.6,
“ERS Control Valve Assembly.”
8. Remove the radiator guard cover (
3
) and the engine
belly pan.
9. Slowly turn the radiator cap to the first stop and allow
any pressure to escape. Remove the radiator cap.
10. Place a suitable container beneath the radiator drain
plug.
11. Place a funnel at the base of the radiator to channel
the drained coolant into the container. Loosen the
drain plug (
4
) and slowly remove to allow the coolant
to drain. Transfer the coolant into a properly labeled
container. Dispose of properly if coolant needs to be
replaced. Replace the radiator drain plug.
12. Loosen the radiator clamp on the top radiator
hose (
5
). Work the hose off the radiator. Position the
hose out of the way to allow radiator removal, or
