Hi jamison, Here's my reasoning. The engine is designed to run at a specific temperature,so the sooner it gets there (without gunning it) efficiently the better. why impede this process ? As vetteoz has pointed out there has been much discussion on this subject, none of which has persuaded me to change. the argument for drilling a small hole or two in the thermostat is only valid as a measure to allow some circulation should it fail to open. Someone please prove me wrong. Roger.

I thought the holes were there to let air bubbles by. So, that you can burp the system and get the air out.

Can you...yes.
Should you....no.

A street driven car will be best served if you replace the OE 'stat with a 180.

These engines are designed to run hot to help keep them internally clean among other reasons. Stay with the 180 degree stat.
