Check your heater control valve. It is located on one of your heater hoses going to the heater core. It is a valve with a few hoses on it and a cable. The valve will typically leak and drip down on the passanger side of the engine and directly onto the ground.

You say I "keep seeing antifreeze under my..."
I'm going to guess you are seeing it under your truck. If that's the case, look at th ebottom of the water pump. There is a "weep hole" that starts to leak when your water pump is failing.

The thermostat is not the problem UNLESS you don't have the casting it sits in tightened securely.

I have a 07 silverado with 39000 miles and i get a burnt fluid smell out of the heat vent after i drive it for a while and come to a stop nothing is leaking on the ground and runs fine

You might not see leaks if the fluid is leaking on the engine where it gets burnt off before dropping to the ground. That happened to me. Check all of the fluid levels. Engine oil, transmission oil, power steering oil and the antifreeze. Check when warm not hot, not cold. Pay special attention to the level and check once each day until you detect which is leaking.

Leaking coolant after radiator replacement

If you are talking about the reservoir that hose is the overflow hose.
Its possible the shop did not release all of the air pockets from the system and some coolant came out with the air bubbles.
The tank should be about half full hot and cold.

We have a 2003 gmc Envoy V6 4X4 Automatic has 108000 miles on it i see that the hose was replaced going to the radiator we smell antifreese under the hood and having to put anti freeze in the over flow...

Well, the fluid from the radiator could be evaporating. Is the upper hose solid when you shut it off?

If you 'smell' antifreeze there 'is' a leak.

Is the fluid 50/50 strength antifreeze to water?

Usually, if there is a leak, it will drip to the ground or come out of the tailpipe (in the case of a bad head gasket).

It is not unusual to have a car with 108,000 mi. to have a leak somewhere.

Keep looking and topping off the fluid.

Leaking antifreeze

first, remember that any leak will run down...There is nothing near your muffler that contains antifreeze, therefore, what ever is leaking has been blown back there while driving. Open up the hood and look to see where leak is originating. check all hoses, hose connections, radiator, rug under heater in the cab and everything associated with cooling system. You will see antifreeze coming out somewhere. Once you locate the leak, I can help you deal with it. Do not open the radiator when engine is hot! Do not drive with low coolant condition! This is not a solution...yet...I'ts the beginning of one!

There is antifreeze leaking from the rear of my 2005 kia sedona. I I am not sure what it is leaking from but there is 2 hoses under there! Why would there be antifreeze in the rear of the van?

many vans have rear heater cores for added passenger comfort, so this is not unusual, it is very possiable either the hoses or there connections to the rear eater core are leaking or the heater core itself is leaking.

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.
