thermo time switch

[Ti Kan]

Look at Bentley manual page 28.37.  It is located on the block, under the
hydraulic pump bracket, with a single blue wire connected to it.  The
resistance from the sensor terminal (wire disconnected) to engine block
ground should be between 60 ohm to 1K ohm depending on temperature.
