13.7) Temperature- and pressure observation
Besides the special checks, see chapter 12.4 and description of the systems find
further maintenance precedures as follows.
NOTE:
13.7.1) Cylinder head temperature sensor
See Pic. 192 and 193.
The two temperature sensors Q are screwed into position on underside of
cylinder head 2 and 3. At cylinder head temperature observation only
temperature of cylinder head material but not of coolant is taken. The max.
operating temperature must not be exceeded. At a rise above the limit check
the following.
At engine operation with 100% anti-
freeze concentrate (without adding
water) possible formation of residues
near sensor might result in too high
temperature indication. Adding of
approx. 20% water will rectify this
fault.

Several temperature control points are located on the Rotax engine
914 F. Refer to wiring diagram in Maintenance Manual.
— cooling system
— temperature sensor
— indicating instrument
— wiring connections
— sensor cable
NOTE:
Grounding connec-
tion of the sensor
direct via the cylinder
head.
For sensor resistance see graph below of sensor resistance over tempera-
ture.
deviation:
At installation secure temperature
sensor with LOCTITE 221 and
tighten to 10 Nm (90 in.lb).
