changing out thermo housings . while i have the thermostat out should i drill a small weep hole or just leave it be ??? its a 180 and functional after the boiling water on stove test..
 
On these cars just put in a 160! I did a 180 and now run a 160. the only way to go. Unless u are in a cold climate for most the year. I drilled a weep hole in the high side of mine as well. Seems to help. I am from the mustang background though...
