I have no idea what you are working on. That should not matter cause it will still get flow. If it can go either way.

What is causing it to leak?

If not radiator hoses, what about heater hoses to and from heater core?
You might also have throttle body heater hoses to and from throttle body.
My biggest problem is I can't see anything from here.

Where is the thermostat located grand am 2000?

Under the radiator hose that meets the top of the engine
under the throttlebody if you follow the heater hose from firewall on the driverside toward the engine it goes to the thermostat housing.

To get to the thermostat you need to remove air cleaner box assembly from the throttle body and move it out of the way. Next, remove the nut at the throttle body that holds the steel tube that goes to the heater hose, remove all hoses that connect to this tube and raise it out of the way. Remove the steel line that goes to the radiator surge tank from the thermostat housing. Now the fun part. With a 13MM box end wrench, loosen the lower bolt from the thermostat housing. A 13 mm socket will remove the top bolt. Remove the thermostat cover and remove the thermostat. Reverse to install.

How do i remove the heater defroster kit and

Loosen the clips holding the coolant hoses and release them, remove the throttle body by undoing the 4 bolts holding it to the plenum chamber. Discard the gasket & fit a new one on refit. (This is after removing the intake hose, and disconnecting the throttle & cruise control cables. Then undoing the clip securing the breather hose and the multiplug).

Drain coolant at the radiator drain. Remove air intake hose and MAF sensor assembly. remove throttle cable bracket and disconnect cable linkage. Remove throttle body bolts and disconnect coolant hoses to throttle body. Loosen heater hose pipe and remove heater hose from rear of pipe. Remove radiator hose from thermostat housing. Remove top thermostat housing bolt. Loosen and almost remove lower thermostat bolt. You will need to slide your wrench and hand under the exhaust crossover pipe to gain access. Loosen the bolt until you can remove the thermostat housing, it should be slotted to clear the bolt. Replace the thermostat and reassemble.

Throttle position sensor

Sounds like you have a vacuum leak somewhere on the engine. If the tps was bad, it would set a code and the check engine light would be on. Also, check your air tube that goes to your throttle body - make sure the hoses are connected tight and the tps is on the throttle body down on the front of your engine where the hose runs down to it. It's not really that hard to get the throttle body off. That would be the best way to change the tps - to take the whole throttle body off and put new gaskets on and tps on it. Hope this helps you out. PHil

Car is leaking antifreeze from underneath of car

I would check and replace the thermostat if it is bad, recheck the connections of the heater hoses to the heater core, and if none of these are bad, the heater core is most likely gone bad. Also, depending on where the overflow canister is, and if the radiator cap has gone bad, it might be letting too much antifreeze out of the system and overfilling the overflow canister.
