3. DESCRIPTION
A. Oil cooler
The cooler is the element of the system which cools the engine oil by means of a section of the engine cooling air duct which runs through it.
The oil cooling system comprises a thermostatic valve which allows cold oil to bypass the oil cooler. As the oil temperature increases, the valve opens slowly, thus directing oil to the cooler. This device prevents cold oil from damaging the cooler and helps to reduce the time required to warm the oil.
An optional additional oil cooler is available.
B. Filter or filtering cartridge
The filter or filtering cartridge is the part of the system which purifies the engine oil. It is located on the engine rear table upper section.

? C. Breather
The breather, located on the L.H. upper section of the engine rear table, is a venting system that prevents an engine sump assembly overpressure by exhausting oil vapours.
A hose connects this breather to a pipe attached to the firewall at L.H. side of power plant. This pipe opens on the engine cowling lower section.
? D. Oil pump
The oil pump provides oil necessary for lubrication and cooling of moving parts. It is a gear and a constant-flow one. It is located at the lower section of the engine rear table ; it is accessible only after removal of the latter.
