Thermostat holes?
What is the reason other than cutting down on air pockets in the engine cooling system are the holes being drilled in the thermostats? Thanks.

they allow a small amount of coolant to flow at all times instead of just when the t-stat is open....beware though if you have too many/ too large holes...the car may not ever warm up properly...
