it isnt a difficult job to replace the thermostat, I had to do it on my old MGB.
I got absolutley no idea where its located on the civic though.

found what i was looking for with a simpler search thanks any ways
Just follow the lower radiator hose to where it connects to the engine. Take off the 2 bolts on that housing and inside it is the thermostat. Just pull the old one out and pop the new one in. Make sure to get a new gasket when you do this. You don't need to drain the radiator but stick a pan or something to catch all the crap that leaks out. Then just run the car and fill back up the radiator.

Don't just remove the thermostat, it has a job to play and is part of the system to regulate the temperature. You need to remember that optimum A/F is delivered by the ECU within a specific temp range. It's also bad news in the winter.
Check the radiator and have it flushed or re-cored - it's prolly clogged. Before that, buy a new thermostat and install it although remember that they usually jam partially open, not fully closed, so this might only be a contributing factor. You might also want to replace the radiator cap - if it's not pressurising the system then that could be the problem. Have the block professionally flushed and you might want to think about replacing the water pump - maybe. Only other thing is that if these areas are stuffed, then it's a good idea to replace the radiator and heater hoses, not to mention all the smaller ancillery ones as they are prolly on their way out. Finally, always run coolant - it protects the radiator etc and flush it every 12 months with a hose and then renew the coolant. Just some ideas

I dont know if anybody knows this (they must) but when you refill your system you have to purge the air out of the top. I had the problem with mine over heating a little bit. I just ran the motor and opened the fitting on the tube on top of the block. It stopped the over heating.

To bleed the air out of the coolant just take off the radiator cap and let the car run, all the bubbles will come out.

Blucivic83 says the car overheats on short distances.
Sounds like the fans aren't coming on. When you're driving 45mph and higher, the air rushing through the radiator is sufficient to cool things down. At slower speeds, or stuck in traffic, you need the fans. Simply taking the thermostat out won't solve the problem. Some cars need the thermostat's restriction to slow down the water so it has time to cool down in the radiator. Taking out the thermostat on those cars CAUSES overheating. Fix it soon, or you'll have to replace a head gasket and get your head milled. Flunky PS-Bleeding the coolant from the 12mm nipple only takes 5 seconds.

Most likely - in fact the stop leak actually clogs your radiator more
 Stop and think about it and you'll see why. It's a cheap fix and not a good one.Get a re-core if you think it's clogged and definitely get the block flushed at the same time. Put a new thermostat in as well as (maybe) a new water pump and your set to go. Also - can't hurt to get your timing checked - just in case it's too far advanced.
