I took the thermostat out, and it was stuck in the open position...I put it in the freezer for about half an hour or so but its still open...I think that this is the reason i tend to overheat during the day and not at night.... Anybody have any input to this assumption?? Any wisdom is greatly appriciated...

Maybe your clutch fan is going out or you radiator is clogged. It could be a number of things but stuck open t stat not one of them if it was stuck close then it would overheat.

actually an open or missing t-stat would make it run hotter because the flow is going through the radiator too fast to actually cool down.
I ran without a t-stat for a week and it would run very cold...for about 30 minutes, then it would just keep getting hotter and hotter, especially on the freeway.

they actually sell thermostats that lock open the first time you use them.. Its made to be more of a water restrictor than a functioning t-stat.

never seen that happen 18 years of wrenching on cars.an a little fyi the water getts hot when the t stat close b/c it stops the flow of water so no t stat the water never stops flow an never will get hot enuff

It won't happen. He must of had some other problem.
The thermostat serves one purpose only. To get the water up to operating temperature. It is not intended to 'slow down the flow through the radiator'. If the flow is slower through the radiator, it's slower through the engine where it heats up even more and causes hot spots, areas in the engine where the coolant boils and reduces cooling.
If anything, you want to get the heated water out of the engine as fast as possible and get it through the radiator. Even on a hot day, the radiator will be a lot cooler than the engine.

the thermostat serves more than just to let the water get up to operating temrature. like said above it also holds the water in the radiator long enough to tranfer heat out of the water and regulate the water temp. why do you think they are designed to open AND close.

That part is fine. What's wrong is the idea that slowing down the water through the radiator is better.
Want more information? Read this by Stewart Water Pumps.

God damn so much information that is wrong floating around in here.
Running without a thermostat can do both of what you guys are saying, too warm, and too cold.
Too warm, the coolant stays in the radiator for a short period to cool down before circulating back into the block. If it wasn't doing that, it would stay warm.
Too cold without thermostat, engine isn't warming up because your cooling system is in good condition.

Is that your opinion or do you have some tech to back that up? Read the tech note from Stewart. You might have seen their sticker on the Sprint Cup cars as they are big in NASCAR.

This is whats happening.to my car... It takes it longer(like 20-40 mins of driving) to even get to operating temp, but on the other hand, if I drive it for like 2 hours in 95+ temps then it will eventually climb to about 220 or so... To me it makes sense that if there wasnt a tstat to regulate the temp and flow, the coolant would constantly flow and would have enough time to cool down before reentering the engine...
