4) General notes on the cooling system
Certification
Essential parts of the cooling system, such as radiator, etc., are available
for this engine from BRP-Powertrain.
Radiator
In an installation as depicted with the radiator (1) in a higher position than
the standard supplied expansion tank (3), a water accumulator (2) has to
be fitted instead of the expansion tank (3). Additionally a suitable expan-
sion tank (3) has to be installed at the highest point of the cooling circuit.
NOTE: Experience has shown that with good airflow, a radiator
with an area of 500 cm² (77.5 in²) is required for trouble-
free operation.

Non-compliance can result in serious injuries or death!
Certification according to the latest regulations, such
as FAR or EASA, must be conducted by the aircraft or
fuselage manufacturer.
Ensure that no contact with hoses or hose clamps of
the engine is given (risk of chafing, wear, loss of coo-
lant) at the installation of external components (gover-
nor, vacuum pump).
The radiator must be designed to dissipate approx.
30 kW (7.58 BTU/s) of thermal energy at take-off per-
formance.
