2.3.15 Cooling system description
2.3.15.1 Cooling system description
The cooling system uses two forms of cooling. The cylinder heads are liquid cooled and the
cylinders ram air cooled. The radiator is located in the front of the lower engine cowling. The
coolant is forced through the radiator by a water pump, driven from the crankshaft to the cylinder
heads. From the top of the cylinder heads the coolant passes on to the expansion tank which
allows for coolant expansion. The expansion tank is closed by a pressure cap with an excess
pressure valve and return valve. When the temperature rises the coolant creates excess pressure,
a relief valve opens and the coolant flows through a thin hose to the overflow bottle mounted on
the firewall.
The engine cooling system is more completely described in documentation supplied with the
engine.
Check the coolant level in the expansion tank (installed on the engine body) before the first flight
of the day - replenish as required up to max. 2/3 of the expansion tank volume.
Check the coolant level in the overflow bottle (installed on the firewall)
–
coolant level volume
should be at least approx. 0.42 pints (0.2 litre).
