liquid coolant
The coolant absorbs excess heat from the engine and transfers it to the air
through the radiator. If the fluid level decreases, the engine overheats and
can be severely damaged.
Check the fluid level every day before driving your CORVUS.
To protect the aluminium parts within the cooling system (the engine and
the radiator) from oxidation and corrosion, use chemical inhibitors in the
coolant. If you do not use an anti-corrosive liquid, the radiator will begin to
rust after a while. This would obstruct the cooling pipes.
NOTE: Initially, the factory uses permanent-type
antifreeze. It contains 50% ethylene glycol and has a freezing point of -35°C.
Liquid chemicals are harmful to the human body. Follow the
manufacturer’s instructions.
The use of incorrect liquid solutions may cause damage to the
engine and the cooling system. Use coolant with a specific corrosion
inhibitor for aluminium engines and radiators in accordance with
the manufacturer’s instructions. If coolant level is correct and the
vehicle temperature keeps increasing, even if its turned on for a few
minutes, it can be due to the presence of bubbles in the circuit and
must be purged. If high temperature still persists contact CORVUS
service.
To avoid burns do not remove the radiator cap or try to change the
fluid when the engine is still hot. Wait until it cools down .
Coolant level:
1. Place the vehicle on a flat surface.
2. Unscrew the cap from the reservoir (1) in an anticlockwise direction and
wait a few seconds until the vapours disperse.
3. Check the coolant level. The liquid must not exceed the line marked
(MAX).
4. If the fluid level is low, add the required amount through the filling
aperture.
Recommended fluid: 50% Long time. (-35°C).
If liquid falls onto the tires, it makes them more slippery and can
cause an accident. Immediately clean any liquid that may fall on
the chassis, engine or wheels. Inspect any old liquid. If you notice
white patches in the liquid, it means that the aluminium parts of the
cooling system are corroded. If the liquid is brown it means that the
steel or iron parts of the system are oxidised.
In both cases, clean the system.
Replace the gaskets with
new ones. Check for any
potential damage, leaks or
lack of gaskets in the cooling
system.
In countries with cold
weather you should adjust
the antifreeze capacity to
your minimum temperature,
adding a margin of -5°C.
