Temperature Sender
The sender is located on the left side of the water flange
that is attached to the front of the engine cylinder head.
There is a blue/white wire attached to the terminal of the
switch (Fig. 30).
1. Lower coolant level in the engine and remove the
high temperature sender.
2. Put switch in a container of oil with a thermometer
and slowly heat the oil (Fig. 31).
CAUTION
Handle the hot oil with extreme care to prevent
personal injury or fire.
Note: Prior to taking resistance readings with a digital
multi meter, short the test leads together. The meter will
display a small resistance value (usually 0.5 ohms or
less). This resistance is due to the internal resistance of
the meter and test leads. Subtract this value from from
the measured value of the component you are testing.
3. Check resistance of the sender with a multimeter
(ohms setting) as the temperature increases.
A. The meter should indicate from 54 to 78 ohms at
200F (93.3C).
B. Replace sender if specification is not met.
4. Install sender to the water flange.
A. Clean threads of water flange and sender thor-
oughly. Apply Permabond #LH150 sealant or equiv-
alent to the threads of the water flange.
B. Screw sender into the water flange and tighten.
C. Connect blue/white wire to sender. Apply skin-
over grease to sender terminal.
5. Fill engine cooling system (see Check Cooling Sys-
tem in Chapter 3 - Kubota Diesel Engine).
