Cooling System - Magni Gyro M16C Ordinary Maintenance Manual

M16 (C) TANDEM TRAINER
MAINTENANCE MANUAL
2.8 COOLING SYSTEM
The cooling system may be described as follows:
1. The coolant flows from the expansion tank of the engine through a hose to the lower connection of the
radiator where it gets cooled.
2. The radiator (size Normal 40 pn 419) is placed vertically, close to the propeller to increase its efficiency.
3. The cooled coolant flows from the radiator through a 180° elbow to the heat exchanger where it cools
the oil.
4. The coolant is sucked by the engine pump from the heat exchanger and flows through a hose.
For the gyroplanes from serial number 16052934 to serial number 22063684, the temperature is kept within the
green range thanks to a radiator choking system consisting of series of fins keyed to a special frame (see fig.
3.13/1). The movement of this frame follows the movement of the Bowden cable pn 403 controlled by the pilot
from the cockpit.
For the gyroplanes serial number 16063694 onward, the temperature is kept within the green range thanks to a
three‐way thermostat fitted to the tubing between the expansion tank and the radiator. The control of the entire
system is done visually as described below.
The control of the cooling system must follow the maintenance schedule as detailed in the Ordinary Maintenance
diagram, or each time there are anomalies, overheating or loss of coolant.
2.9 INSTRUMENTATION
All maintenance other than changing the battery must be carried out by an authorized workshop.
Any instrument that gives readings that are suspected to be wrong are to be replaced and a functional check of the
system must be carried out.
Limit and range markings are to be clear and legible; they must be replaced when they no longer comply with a
satisfactory standard.
Limits and ranges of each engine instrument can be found in the relevant sections of the ROTAX engine manual.
