D-3.7 ENGINE COOLING SYSTEM
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.
•
Every week, before starting working (when the
coolant is cold), check the coolant level which shall
be kept at 2 centimetres from plug
•
When necessary, add clean water or an antifreeze
mixture through cap
•
Change the antifreeze mixture every two years.
To drain the antifreeze:
- Let the engine cool down
- Unscrew the plug
or disconnect the rubber hose, if no plug is
present. Allow the coolant to flow out into a
special container.
- Refit the hose and pour new antifreeze (50%
water-antifreeze). This proportion will provide
protection up to -38°C.
•
Daily clean the radiator grille using a brush with
hard bristles or compressed air at a max pressure
of 6 bar.
