Temperature Sender (Gr3200) - Toro Greensmaster 3200 Service Manual

Temperature Sender (GR 3200)
The switch is located on the side of the water pump.
There is a blue wire attached to the switch.
Allow the engine to cool to a safe tempera-
ture before removing the temperature send-
er from the engine.
1. Lower the coolant level in the engine and remove
the high temperature sender.
2. Allow enough time so the temperature switch can
cool to room temperature of 70 F (21 C).
Note: When operating at normal engine tempera-
tures, the temperature sender is extremely accurate. To
accurately test the sender requires an elaborate test
setup and special calculations. It might be more cost ef-
fective to replace the unit. The following step is a quick
check of the sender.
3. Check the continuity of the sender with a multimeter
(ohms setting). The sender should be between 2.5 to 3.0
Kohms.
