CHANGE THE ENGINE COOLANT
DANGER
When the coolant is hot, the cooling system is under
pressure. With warm engine, loosen the radiator plug
slowly and carefully, without removing it, to drain the
pressure. Use protection gloves and keep your face
at a safe distance.
To drain the antifreeze:
-
Let the engine cool down and remove the plug A.
-
Using a screwdriver, loosen the clamp and remove
the rubber hose B. Allow the coolant to flow out into
a special container.
-
Refit the hose and pour new antifreeze (50% water-
antifreeze) in the plug A. This proportion will provide
protection up to -38°C.
-
Refit the plug A and start the Diesel engine. After few
minutes, check the level by the hole C. If necessary,
add new coolant until it is level.
On delivery, the machine is filled with a cooling mixture
consisting of 50% water and 50% anti-freeze.
