03-07 COOLANT TEMP
Emergency operation procedure
1 Coolant Temperature High
COOLANT TEMP
Engine coolant temperature is in the upper red range (too high / above 105 °C).
Coolant temperatures above the limit value of 105 °C can lead to a total loss of power due to engine failure.
A COOLANT LVL caution message....................................................................................................check
If COOLANT LVL is displayed
B POWER.........................................................................................................................................reduce
C COWL FLAP.....................................................................................................................................open
D Expect loss of coolant.

If COOLANT LVL is NOT displayed
During climb
F POWER............................................................................................reduce by 10% or more as required
G COWL FLAP.....................................................................................................................................open
H Airspeed...................................................................................increase by 10 KIAS or more as required
I COOLANT TEMP..................................................................................................check for green range
If the coolant temperature does not reach the green range within 60 seconds, reduce power as far as
possible and increase airspeed.
J If the coolant temperature does not return to the green range perform a precautionary landing on the
