[Vwdiesel] 1.9TD Glow Plugs

[Wade Yorke]

I have a 1984 Westfalia that has just had a 1.9TD installed.  The 
engine has a gear reduction starter so does not spin the engine over as 
fast as the diesel starter.  The engine starts immediately when the 
glow plugs are used, or when the engine is being restarted after a few 
minutes of being shut off.  If it sits for an hour it takes quite a bit 
of cranking (5 seconds or so) to start.  In these situations, the 
engine is warm enough for the glow plugs not to come on.
  Someone suggested removing the wire from the  sensor  that reads the 
engine temperature, so the glow plugs come on everytime.
What are your thoughts and where is this sensor located?
