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!

Here is a pic of the summer (180*) t'stat I just removed. I drilled 2 holes in it cause I wanted a little more cooling effect, but you only need one for an air bleed. This shows where to drill in the flange - away from the rubber seal, and away from the sealing edge for the core of the 'stat

either that over flow tank is REALLY full or REALLY dirty...both need addressing.
And that is a big mess of wires.
52k or 5 years overdue
yeah that is bill and I getting off topic. I think the bottle of dexcool I used said every 5 years of 50,000 miles it should be flushed. So I am 5 years or 52k over due depending how you look at it.

I know I'm overdue, I'm going to replace it tomorrow...new question / problem now.
In one word, my temp guage is all over the place now. For example, cruising on the highway itll be a good chunk below 200, but when I'm sitting letting the car idle it'll actually gove just a tiny bit above 200. It never goes over like 203-5. Is this normal?
I have pics, I'll upload them tonight when I get off of work.

Here are some pics of my temp guage...
This is how it is when idling, sometimes lower but never higher.
This is around-town driving, highway driving is a little lower.
Thanks
