[Vwdiesel] VW Diesel engine running too hot

[Rudy]

Make sure all the cooling system components are working properly, install an
87 degree Celsius Thermostat and run it.  195 to 200 degrees F is not too
hot.

Over-heating:
  Here are the symptom:
   
  I have a very nice 83 Westy with the 1900 engine and a 5 speed; however,
it runs with the needle straight up or even a little to the right of top
center. This is too hot. I do not like for it to run this hot. (My 82 also
did this same thing, and I experienced early engine failure because of it.) 
   
  Over and over again, I have checked this out at cooler times and in cooler
climates. At those times the nettle always stays where it belongs--in the
LITTLE BOX on the temperature gauge--to the left. This position is where the
engine thermostat should normally keep the engine temperature. The
temperature must be controlled by the thermostats--not by the radiator fan.
   
  I believe this is an engineering problem. I have had only one Diesel
Rabbit that always ran inside the little box on the heater gauge. All of the
rest of them have run much hotter than their thermostat. Overheating these
engines is a number one cause for early engine failure. 
   
  Is there a radiator capacity problem here? Is the radiator too small, or
does the radiator have fewer fins than it needs? The problem is not the
engine nor the thermostat. It has to do with cooling.
   
  My experience with all VW diesels (and I have had many) has been that they
are IMPROPERLY ENGINEERED to run as cool as they should--else why do they
all run hotter than their thermostat would otherwise allow? 
   
  (Do ya'll understand what I'm trying to explain here?)
   
  So now here is my question: 
   
  What has been your experience for SOLVING this problem.
   
  Thanks to all of you,
   
  Sherwin
