Engine (continued)
Checking the Coolant Level
1
Park the Machine on Level Ground
Stop the engine and let it cool down. Open the engine
compartment.
!
WARNING
The cooling system is pressurised when the coolant is
hot. Hot coolant will burn you. Make sure that the
engine is cool before checking the coolant level or
draining the system.

2
Release System Pressure
For location of engine cooling radiator, refer to
Component Location Diagrams
at the end of this
section.
Carefully slacken cap
A
. Let any pressure escape.
Remove the cap.
3
Check the Level
The level should be between the FULL and LOW
marks on the expansion bottle
B
. Top up the bottle
with pre-mixed water/antifreeze if necessary. See
Coolant Mixtures
.
4
Refit the Pressure Cap A
Make sure it is tight.
Note:
Check the quality of the antifreeze mixture every
year - before the cold weather starts. Change it every two
years.
Coolant Mixtures
To prevent the coolant freezing in cold conditions,
antifreeze must be added. JCB Universal Antifreeze will
give protection down to the temperatures shown in the
table.
Antifreeze Solution
Starts to freeze at
55%
-36 °C (-33 °F)
Never use less than a 50% solution otherwise there will
not be enough corrosion protection.
Never use more than 60% solution otherwise the cooling
system may be damaged.
Leave the antifreeze in all the year round as it gives
protection against corrosion.
Check the strength of antifreeze solution at least once a
year, preferably at the start of the cold period. Always
renew the antifreeze every two years.
A 50% antifreeze mixture should be used even if frost
protection is not needed. This gives protection against
corrosion and raises the coolant's boiling point.
