Coolant Mixtures
To prevent the coolant freezing in cold conditions, antifreeze
must be added. On Peugeot engine machines use Inhibited
Ethanediol AL-39 antifreeze (JCB Part Number 4006/0200).
Solution Starts to freeze at
50% - 37 °C (- 35 °F)
On Perkins engine machines use JCB Universal Antifreeze.
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.

Checking the Coolant Level
1 Park the machine on level ground. Stop the engine and
let it cool down.
2
Carefully loosen the cooling system filler cap

just
enough to let any pressure escape. Remove the cap
when all pressure is released.
3
If necessary top up the system to the level indicated
inside the expansion/filler bottle.
4 Refit the filler cap and make sure it is tight.
5 Run the engine for a while to raise the coolant to working
temperature and pressure. Stop the engine and check
for leaks.
