[W126 Coupe] Overheating

[Jonathan Hodgman]

Yes it will lower the temp from 105 to about 95.  A  Worthwhile 
mod...All my cars are running it.  For the moment a radio shack resistor 
is OK, but you Really want to scare up some mil spec resistors.


If ya'll can't find them I've always got a bunch here.
