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, see 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/anti-freeze 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 Four Seasons Antifreeze and
Summer Coolant 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.
