Also my original did have something close to a small rivet through a hole that jiggled back and forth that looked as if it could be the weep hole you are talking about.
If the one I have in now does not have the weep hole that could be causing the overheating problem?
Yes that is the weep hole. Some of them just have a small notch in the edge of the valve instead of the hole. The quality control on the notch is poor on some of them and it's too small or no hole at all.
If an air pocket is trapped in the thermostat housing the thermostat will not open.

Sorry it's been so long since I've added my status to this post, but a few things came up and the the cougar was on hold for a bit.  I usually like to finish a post so that anyone else searching the forums can get any help they need by just reading previous postings. So...I drained and flushed the system again. Put a new thermostat (like the 4th or 5th one). This time is was a Valucraft 192 degree from Autozone. This is the only one I could find with a weep hole that actually locked into place like the original manuals say they should. I also took off the water pump and replaced it even though when I took off the original it still looked brand new. I thought I'd throw the new one on there since I already had it all apart. And too anyone is the future who wants to remove the water pump, it is not as hard as it looks. Took me about 2 hours at most. Just make sure you keep the bolts in the right order since all of them are different sizes.And use a torque wrench at 16-18lbs. So with the new thermostat, water pump, radiator cap, radiator, temp sending units and fan clutch. It now heats up a bit below the half way mark even though it takes a good time before it reaches it that. I'll just say that is due to the outside temperatures and say it is good for now. I'm not sure what fixed the problem to be honest since the last thing I changed the was the water pump(even though the other looked brand new) and another thermostat at the same time. But I can recommended the Valucraft for when you have to change your thermostat since it's the only one that seem to lock in place for me.

It's good you fixed it. If the water pump was original it may have been your problem. The water pump is stupid easy to do. The only thing you really have to worry about is breaking the two lower bolts on each side of the pump that go through the timing cover. They have a tendency to snap off as they pass through a water jacket and can get crusty.

Yea some of the bolts were a bit aged, but not as bad as I had as I thought they would be. Does anyone know where I can get some new bolts for it? I really wanted to put new ones in it this time around, but I couldnt find any. Autozone had some that would fit, but did not have a complete set. If it every comes down to it i could always make my own, but I dont mind taking the easy route sometimes and spending the few extra bucks.
