Thats WAY too high for a street machine. Something is definately 
wrong.
At highway speeds, your car should run very cool. (about 180-200. Lots 
of air flowing through the radiator) 250?! Yikes!!!

You know, I've had this problem (not the 250 degrees problem) for 
quite some time.  While driving around town and on the highway, my 
temp guage roams around 100 to 110 degrees celsius, occasionally 
hitting about 112 degrees.  I replaced the old thermostat about two 
months ago with a 175 degree F thermo, hoping that my temp would come 
down.  I have had my cooling pressure tested and everything came out 
O.K.  I have also replaced various heater hoses and the heater valve. 
 I was under the impression that this was normal for earlier VW's, if 
this is not the case, please, someone let me know.

One other question, what ration should I be using when replacing my 
antifreeze?
