Bad News. I recently had the same type of smell ( no leaks or puddles either) coming from my van and had to have the intake manifold gasket replaced due to the Dex-cool issue. It appears GM installed an inadequate/substandard gasket when they built the van. My van only had 65,000 miles on it. There's a Dex-cool settlement you could have applied for but repairs had to be made by May of 2008.
This is the only real complaint I've had with the van.

You may have a stuck closed thermostat or the impeller has failed on the water pump.
Replace them both. You never trust a stat that has gotten hot, and there is no sure fire way to test. You can take it out, put the car back together and see if the engine still gets hot to determine if it's the stat, or the water pump, but once you do all that, you might as well just replace them both.
You also need to make sure the radiator is not all slugged as well, and make sure the radiator cooling fans are both working.
There is a cooling fan relay that is prone to failure as well. Mine did in my '03 Jeep Cherokee. It's located behind the right headlight, and requires that you remove the headlight, drill a hole in the plastic shield, and replacing the relay. You can get a new one at the auto parts store.

it sounds like a possible head gasket problem,you can get the fluctuation from combustion gases getting pumped into your cooling system and creating gas pockets,i would suggest taking it to a shop and have them do a block test to look for combustion in the cooling system to confirm the problem,that way you will know for sure,if it comes up negative they can also perform a flow test to make sure there is no restriction in the cooling system such as a plugged radiator or a bad thermostat,hope this sheds a little light on it

Testimonial: "I bet you've hit on the problem ! Car has been "using " antifreeze for a couple years now, with no leaking anywhere. Lost through the head gasket ?"

First of all you have a bad heater core that needs to be replaced. Second you may have a bad temperature sensor. Make sure the radiator if full of water
