Vig..the T stat can be drilled for the SC applications. See Willwrens mods. He'* has good pics of it.

CC...time for a flush.

I guess I'd might as well flush it. How many gallons do our cars take?

There'* a huge rack of pre-mixed dexcool at my work, I can take as much as I want.

It can be done for non-super charged applications too.

Any tips on removing vacuum lines? I can't get the two off of the throttle body.

You shouldn't have to remove vacuum lines to change the thermostat. The only thing you'd want to remove would be the upper radiator hose. You can also remove the air intake snorkel for more room, if you'd like...although it'* not necessary.

Tstat successfully installed!

One question: I forgot to pour coolant in where the thermostat goes...but I filled the radiator and overflow back up. Is it okay for me to start the car?

As long as everything'* full, you're good to go to start the car.

Fire it up and check for leaks around the t-stat housing and also at either end of the radiator hose. It won't hurt to climb under the car to validate you have the pet **** completely turned off, either.

Once you start the car open the bleeder vent on top of the t-stat housing. Once fluid oozes out from it, close it. That will ensure you have removed all the air from the system.

The fluid level will drop in the car once the engine reaches operating temp (thermostat opening). Add coolant to the overflow jug to bring the level back to the normal range.

Good job!
