Re: T-stat to drill a hole or not to drill a hole?
It isn't anything new. It is an old racer modification. I was doing it back in the 80's. The reason is that it makes it easier to vent air out when refilling the water. Used to be you were allowed to dump the water out of your radiator between rounds and refill it to cool the motor down for the next round. Some guys used to put little valves in the top of the intake water passages to vent air too.
