Re: I am trying t out how to set the thermastat it is
You should probably just replace it with a new tstat from home depot or lowes. the wiring is only very low voltage wont hurt you but shut down your unit. wiring is pretty basic even for someone with no experience and a screwdriver or two. look for a digital non programable thermostat if you want one that gives you a digital number and basic on and off operation. If you want programming functions buy a programable.
to reprogram what you have on most tstats you need to get into your program set up by pressing a button that says PRGM or something of the sort and go through day by day and time by time and set up the schedule for the temperatures that you want. To override most program functions you should usually just set your system switch to heat or cool then raise or lower your desired temp setting and hit the HOLD button if you have done this and nothing is happening with your system try just turning your fan switch into the on position if you can get the fan to come on then you know you are getting power to the system and some stuff is working but you have a problem of some sort and may well need to call in a pro.
Always do business with a company who offers you multiple repair and renovation options along with planned service which is something you need to do on a yearly basis(about 2-300 dollars a year). Run away from a company that just comes in and trys to say you just need to replace the system. It can almost always be fixed and backed up by a good warranty like 1-5 year guarrantee on a repair.

YES! DRAIN THE RADIATOR! THE THERMASTAT IS AT THE ENGINE SIDE OF THE TOP RADIATOR HOSE! REMOVE THE HOSE! AND THE THERMASTAT HOUSING HAS TWO BOLTS HOLDING IT ON! REMOVE THE TWO BOLTS, AND THE HOUSING! CLEAN THE AREA AROUND THE BASE OF THE HOUSING! SCRAP OFF THE OLD GASKET FROM THE HOUSING, AND ON THE ENGINE! REPLACE THE GASKET WITH A NEW ONE! PLACE THE NEW THERMASTAT IN THE SAME DIRECTION AS THE OLD ONE COMES OUT! REPLACE THE HOUSING, TIGHTEN THE BOLTS, AND PUT THE RADIATOR HOSE BACK ON, RETIGHTEN IT, AND FILL WITH ANTIFREEZE, AND CHECK FOR LEAKS!
Your Thermastat is located in a Dome Shaped Housing,just take your hand put it on upper radiator hose and follow it to the engine ,you'll run into a hose clamp around the hose thats holding it on the Thermastat Housing.
Make sure your car is cold, then put a pan underneath vehicle below the thermastat housing,You'll loose a Little Coolant ,So this Way you can catch it.
Just Loosen the Rad. Hose Clamp and Pull off the Hose from the Thermastat Housing.Then you'll have a couple bolts holding on the Housing,Remove the Bolts and The Housing should be FREE to come off.If its a Little Stubborn ,Lightly Tap on It with a Plastic or Rubber Hammer a nd it will come off.Your Thermastat is under the Housing.
After off Clean Both Surfaces on the Housing remove All the Old Gasket material and Gasket Sealer .Then just put your new thermastat housing in with the Spring part facing Up.
Put Gasket Sealer on The Thermastat Housing and Put new Gasket on and Line up your Bolts Holes.
And Also piut a Small bead og Gasket Sealer on The Engines Surface. Tighten Down Good and Snug ,But Don't Over Tighten.
Put the Hose back on Tighten Clamp and Fill Radiator Back up to Top.

yes, you can do it with minimal tools. First though, please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat .These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.
Here is the procedure for your car:
Disconnect the negative battery cable.
Drain the coolant.
Remove the air intake duct.
Disconnect the radiator hose
Remove the thermostat housing.
Remove the thermostat.
Clean all sealing surfaces.
Fig. Thermostat and housing-typical
Install the thermostat.
Install the thermostat housing using a new gasket.
Install the thermostat housing bolts and tighten as follows:
Hi: You'll first want to Drain your Radiator take your radiator cap off so when drain it the coolant will drain freely.Then Drain your raditor you'll find a Drain Tee outlet on the inside bottom of your radiator. And catch the Coolant in a Drain Pan. Standing in Front of your Vehicle you'll see a Hose connected to your Radiator(UPPER RADIATOR HOSE) take your Hand and follow it down to your Engine until you locat a Hose Clamp Remove the hose clamp and work off the top Radiator Hose.Where you removed the hose theres a Dome Shaped Metal Housing,with 2 bolts in it. Take those 2-Bolts out and Remove the Dome Thermastat Housing,Under it You'll Find your Thermostat it shuold come out with a little Resistance. Once its out, Clean Up The Thermastat Dome of any Gasket still left on it, and clean where you remove the Thermastat Surface.To put back just Reverse the Removal Be-sure your Thermastat is put in right and not up side down.Then get some Gasket Sealer Put a Little on the Thermastat Housing where gasket goes and some on the Enging surface and Install your New Thermastat,Be careful when Tightening the 2-Bolts on The Housing. not to Over tighten them.The torque Specs on the 2 bolts range between 10- 15 Foot pounds.You don't want to Strip,
After you get your New Thermastat in and your Radiator Hose on and Clamped.Make Sure you have closed the Drain outlet. then fill with coolant,if your coolant is old i recommend putting new coolant in. I hope this helps You.I;m Sure it Will, But please let me Know through FIXYA by Voting and a Testamony.This way I'll know that my solution was Helpful. Thanks From d_hubbs
First make sure engine is cool.
-Put drain pan under car, coolant will run out.
-Remove the TOP radiator hose that runs to the metal thermastat housing. Coolant will now be running out, try and direct it to the drain pan below.
-Remove the thermastat housing, BEFORE removing the thermastat make sure you TAKE NOTE at how it is situated in the casting.
- Take the thermastat housing and run a wire brush on the flat spot were the old gasket material is.
-Both mating sides of the thermastat housing MUST BE PERFECTLY CLEAN. There can not be any old gasket material left.
-Insatll new thermastat.
-Put a very light amount of PERMATEX orange high temp. silicone on BOTH sides of the new gasket.
-Put a small amount on bolt threads also.
-Now install thermastat housing, and bolts.
-Tighten bolts down a little at a time, alternating between the two, unitl till they are tight.
-Install the radiator hose, and tighten hose clamp.
-Remove radiator cap, pour in coolant, until it sits just below the radiator cap neck. This may take a little time as the system has some air in it.
-Install the radiator cap. Make sure you radiator overflow tank is filled properly.
-Remove the drain pan, make SURE ALL the tools use used are secure, and out of the engine bay.
-Start engine, and place your heater control to 'HEAT"
-Let engine run until the top radiator hose is hot, which means you thermastat has opened.
-Keep watching the engine temp AT ALL TIMES, we wnat to make sure there is no air in the system.
-Inspect for any leaks. Now when the top radiator hose is hot make sure the hose clamp is tight.
Please let me know how it goes.
