COOLANT TEMPERATURE TOO HIGH (RED RANGE):
(1) Increase airspeed and reduce power as quickly as possible
(2) Cabin Heat - COLD
(3) If coolant temperature reduces rapidly to normal range,
continue to fly normally and monitor coolant temperature,
Cabin Heat.
(4) If coolant temperature does not decrease,
i) Land as soon as possible
ii) Be prepared for an emergency landing
iii) Expect an engine failure
"WATER LEVEL" LIGHT ILLUMINATES
(1) Increase airspeed and reduce power as quickly as possible
(2) Coolant temperature "CT" check and observe
(3) Oil temperature "OT" check and observe
(4) If coolant temperature and/or oil temperature are rising into
amber or red range,
i) Land as soon as possible
ii) Be prepared for an emergency landing
iii) Expect an engine failure
GEARBOX TEMPERATURE TOO HIGH (RED RANGE):
(1) Reduce power to 55% - 75% as quickly as possible
(2) Land as soon as possible

FUEL TEMPERATURE TOO HIGH:

(1) Switch to fuel tank with lower fuel temperature, if this con-
tains sufficient fuel
(2) Reduce engine power, if possible
(3) If fuel temperature remains in Red Range, land as soon as
possible
