Replacement Of Cooling System Hoses - Magni Gyro M16C Ordinary Maintenance Manual

3.13.6 REPLACEMENT OF COOLING SYSTEM HOSES
(See Fig. 3.13/1 ‐ 3.13/3)
1. Before starting verify that the engine's ignition key and push‐button are in OFF position and that all the
breakers are switched OFF;
2. Loosen the clamp pn 384 that attaches the hose pn 1240 to the lower connection of the radiator;
3. Have a tray (5) ready to collect the coolant;
4. Gently remove the hose pn 1240 from the connection and direct the liquid into the tray;
5. To allow the complete discharge of the coolant from the cooling system, remove the cap (2) of the
engine's expansion tank (3, fig. 3.15/1);
6. Loosen the clamps that fix the damaged hose to the connections;
7. Remove the damaged hose from the connections;
8. Carefully check the worn part of the hose and find out the point of contact where it has been damaged.
9. If possible, avoid further rubbing with the hose, either using some rubber spacer, anti‐rubbing sheath or
removing the sharp contact edges;
10. Replace the hose, taking care to restore the original layout of the cooling system;
11. Fasten the clamps pn 384 of the hoses to attach them to their connections;
12. Fill the system from the engine's expansion tank, as per level instruction of paragraph 3.13.7 "Coolant
level";
13. Close the cap of the expansion tank.
3.13.7 COOLANT LEVEL
Magni Gyro uses the following coolant:
SHELL ANTIFREEZE ‐26° +122°
Dilution rate 40%
WARNING DANGER:
The coolant level must be checked before each flight. If the engine is hot, be cautious when removing
the cap of the expansion tank.
WARNING DANGER:
When the engine is hot, the coolant may be pressurized and careless opening of the cap may generate
spurting and spreading of hot liquid.
When the engine is cold, the correct level of the coolant is reached when the ROTAX engine's expansion tank is full
and the level inside the recovery reservoir (3) is at its minimum.
If this is not the case, fill up with coolant.
WARNING:
Whenever coolant is replaced during maintenance to the cooling system, always check the levels after
the first start‐up.
