I am replacing a leaking thermostat gasket and will replace thermostat while apart. Currently it has a 195* and works fine holding temp a 195*. Autoparts store suggested to put a 180* to run it a little cooler. Good, Bad or Indifferent? Secondly: I have read in the past about drilling an 1/8 hole in the thermostat flange to relieve an air bubble if it forms at the thermostat. Anyone do this? Autoparts store said many already come with a hole. The Stant I bought did not.
Thank you, Krister Meister '66 SS #'s
