Default Re: Temperature

My experience has been that drilling extra holes effects the calibration. Runs colder. If you look at a thermostat closely you will see bleeding air is designed into the thermostat. Don't try to out engineer the engineers. If Stant or other manufactures thought they needed extra holes, they would have drilled them. I never saw Ford or GM install thermostats with extra holes. This is my opinion only.
