Maintenance Manual
3.13) Radiator (optional 912/ 914 Series)
Clean radiator elements and check for damage, straighten fins if necessary. In
particular, check the hose connections and the support plates. Check for
tightness if leaks are suspected.
3.14) Cooling air duct (optional 912/ 914 Series)
The cylinders are ram-air cooled. The cooling air is pushed during flight and by
the propeller into the engine compartment and is distributed evenly by the
cooling air duct to the individual cylinders. Carry out visual inspection for
damage, cracks, chafing marks, burnt spots etc. In the event of noticeable
damage, replace the cooling air duct.
3.15) Expansion tank
See Fig. 75-12
See latest valid Maintenance Manual “Line Maintenance“ of the corresponding
engine type. On newer engines the expansion tank is in a different position. See
therefore the latest issue of the Service Information “Running modification” SI-
912-020 and SI-914-022 respectively.
◆
NOTE:
On engines with the old expansion tank, the old hose locations
and the old coolant hoses don’t have to be upgraded and can be
continued to be used.
