Inspection; Instalation - Suzuki AN650 2002 Service Manual

INSPECTION

• Check the engine coolant temperature by testing it at the
bench as shown in the figure. Connect the temperature sen-
sor 1 to a circuit tester and place it in the oil contained in a
pan, which is placed on a stove.
• Heat the water to raise its temperature slowly and read the
column thermometer 2 and the ohmmeter.
• If the temperature sensor ohmic valve does not change in the
proportion indicated, replace it with a new one.

If the resistance noted to show infinty or too much different resis-
tance value, replace the temperature sensor with a new one.
* Take special care when handling the temperature
sensor. It may cause damage if it gets a sharp
impact.
* Do not contact the engine coolant temperature sen-
sor 1 and the column thermometer 2 with a pan.
