would someone please tell me what the drilled thermostat does. and how you go about drilling it... also. what is the benefits of doing this.

thanks everyone!

The function/benefit of running a drilled thermostat is that it helps to bleed out air from the engine'* cooling system. There is some disagreement on whether to drill or not to drill the t-stat on the forum.

If you scroll to the 4th post down, you can see approximately where to drill the hole. It states the size that many drill as well.

By the way, it'* a good idea to list your car'* year as well as trim level by editing your profile.(top right hand side, "profile" link)

Hope this helps

Edge..please put your year and model into the signature area of your profile as Rusted mentions.. It'll help in the future.

The basics of the one or two small holes is to help bleed the air as well as allow a slight amount of bypass on the SC'd cars.

A 180 non-drilled tends to be perfect for light to moderately modded engines.
A 180 drilled gives you a slight edge if you plan on racing the car professionally with some slightly heavier mods (headers, cam, etc).
A 160 is for hardcore racing only if you ask me.

The drilled t-stat has the advantage of always allowing a trickle of fluid to circulate even if it isn't warm enough to open completely. Note that this usually will cause your heat to take a very long time to get warm in the winter.
