From what I said I did does it sound like I did it correctly so far?

Sounds like you're okay so far. Might want to check for that seal, though. And maybe try burping the system a bit more? You'll know it's done when antifreeze is the only thing dribbling out of the bleeder on the thermostat housing.
When I drilled my 180* stat (bought the more expensive AutoZone part, looks identical to the Intense stat), the hole was covered a wee tiny bit by the rubber seal. Installed it with the hole at the 12 o'clock position, checked the antifreeze level, burped the car a lot, anally checked the level over the next few days, and haven't looked back. I like my car all nice and chilled out at 180* F. My right foot likes it too!

Learn from the mistakes of others, that way when you mess up you can do so in new and interesting ways.
I have a 180 stat and she still runs pretty hot, mainly due to the fact the fans don't turn on until about 208 (according to scan tool). The "quick fix" solution is to do the high speed fan bypass mod where the PCM pin is grounded through an on/off switch. Not the most sophisticated or pretty but it does work, keeps temps under 200 easy. http://www.pontiacbonnevilleclub.com/fo ... f=8&t=5042 It does set a code but does not trip the CEL.

I havent burped it yet due to the fact I still cant find the *dang* gasket. When I can get a ride Im headin to Oreilly Auto today to get a new one and start workin on the car again. I feel like a little schoolgirl all excited about such small things I get to do lol

I have been thinking on getting a fan switch and mounting it on my center console. I always wondered about that tho, I would forget to turn the fan off so basically it would always be on as the car was on, would that harm anything?

I think your car won't get up to operating temp as quick but apparently guys here just wire in a lighted switch to show it's on so you don't forget.

The car will get up to temp just as fast as with OEM. Just that the max temp it can reach when you're moving is lower.
Is there any way to reprogram your OBDI computer to have the fans on at 180*? I know that's possible with OBDII (love those lowered fans on my car). Save you some hassle wiring up things.

Ok I have a problem. Im following the exact instructions
"Fill the radiator slowly at the cap opening with coolant. You should see and hear air bubbles disturbing the surface of the coolant in the intake manifold at the thermostat housing as they are pushed up and out of the engine."
When I took off the stat housing the coolant just kept flowing out, I put a pan underneath to catch what I could. Now it looks like the radiator is entirely empty and the housing has coolant to the brim. I start filling the radiator and instead of hearing bubbles the coolant just keeps flowing out of the housing.
Does that just mean there is no air trapped and I can continue with the install?
