Engine (cont'd)
Cleaning the Coolant Radiator
1 Park the machine on level ground within reach of a
compressed air line. Stop the engine and remove the
key. Open the bonnet and remove outer radiator grille
by unscrewing fastener D and lifting off the grille.
2 After allowing the engine to cool down use compressed
air to remove debris from the radiator E.
3 Use a brush to remove any further debris.
4 Inspect the radiator for damage.
5 Refit the outer radiator grille, screwing fastener D hand
tight, and close the bonnet.
Coolant Mixtures
To prevent the coolant freezing in cold conditions, antifreeze
must be added. On XUD engine machines use Inhibited
Ethanediol AL-39 antifreeze (JCB Part Number 4006/0200).
Solution Starts to freeze at
50% - 37 °C (- 35 °F)
On 100 and 400 series engine machines use JCB Four
Seasons Antifreeze and Summer Coolant.
Solution Maintains circulation Protects against
down to damage down to
deg C deg F deg C deg F
50% -33 -27 -45 -49
Never use less than 45% antifreeze solution otherwise there
will not be enough corrosion protection.
Never use more than 50% antifreeze 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 solution should be used even if frost
protection is not needed. This gives protection against
corrosion and raises the coolant's boiling point.

WARNING
Antifreeze can be harmful. Obey the manufacturer's
instructions when handling neat or diluted antifreeze.

WARNING
The cooling system is pressurised when the coolant is
hot. Hot coolant will burn you. Make sure the engine is
cool before checking the coolant level or draining the
system.
