Good question: The thermostate acts as a valve (of sorts) allowing the engine to stay at a relative constant temp. If run without an engine will typically run too cool (this is not good as engines are designed to run at specific heats for best efficiency and motor oil too is designed to run a a designed heat. An engine can go the other way too and over heat. As mentioned the thermostate acts like a valve controling the flow of coolant thru the block and radiator. The run thru block is a long one and it will certainly pick-up heat however running without may cause the coolant to run too quickly thru the radiator so little heat will be lost. (imagine a lit candle run your finger thru it quickly and no heat exchange as it you will not burn your finger, slower you'll get the heat from the candle and burn your finger. In short use a thermostate, your engine was trully engineered to have one.

I hope this expalins it for you,
Tom

Where is the thermostat located on my 2006 Saturn ion 2.2L?


Under the thermostat housing mounted on the engine at the "engine side" of the upper radiator hose. That "usually" happens when the thermos is stuck open & the computer is getting cool readings from the anti freeze because its flowing too freely. More fuel is added due to bad temp readings. Drain some coolant, remove rad cap, remove thermos housing, Clean gasket or r/r O ring & replace thermostat. Reinstall. Refill cooling system, let it run.refill overflow bottle after warmed up. Ck for heat & leaks. Good luck

What happen when I remove out the thermostat?


the thermostat opens and closes to allow the coolant to flow in when it's supposed to and out to cool the engine and keep the engine temperature steady. The part is there for a reason and purpose. I would replace it before you have an issue.

Engine over heats


Check for collapsed radiator hose first.

Do the cooling fans come on? If not, check fuse, relay and if still no function- fan thermostat switch.

If fans do come on, replace water pump.

Lincoln ls car is still running hot after changing thermostat


First when car is running hot stop and pop the hood check and see if the electric cooling fans are running. Second have your radiator cap checked, replace if bad. If neither or these are the issue, with the engine cold start it up and remove the radiator cap. It will take a couple minutes for the engine to warm up enough to open the thermostat. After it gets warm enough that your thermostat opens, (5 to 10 minutes) you should see the fluid in the radiator start to circulate. If this doesn't happen your water pump is out and needs to be replaced. Back to the first thing if your fans aren't kicking on check all your fuses in your engine compartment first. If you narrow down the problem to one of these and need more assistance, just reply to this comment and I will help you further.

Radiator fan running after engine turned off on 98 nissan altima


You need to diagnose the problem. The fan is doing what it is being told to do by the computer. You stated the temp gage on the dash is in the HOT position. Either the engine is very hot and the fan needs to run to remove heat even after it is shut off or the gage, coolant sensor or temp sender is defective. Try running it temporarly without a thermostat and see what happens, you may have bought a defective thermostat.

How to Replace Thermostat


Drain the cooling system down a little bit. Remove the upper radiator hose and heater hose from the thermostat housing. Remove the two bolts holding the housing to the head. Remove the thermostat and clean off the old gasket. Install the new thermostat and gasket and reassemble. Top off the cooling system. Run the engine and check for leaks.

Changing the thermostat


It's not hard, just a bit messy. Follow the top hose that runs from the radiator to the engine. Where it stops is the location of the thermostat. You will need to drain the coolant out of the radiator before you begin taking things apart. Be prepared to replace the coolant with new coolant mixed 50-50 with water when you are done.
Go to the parts store and get a new thermostat for that year/engine/model combination. Remove the hose from the thermostat housing, remove the housing and pull the thermostat out. Note how the spring on the thermostat faces. Clear out any gasket material that remains with a soft scraper -don't damage the area where the housing goes or it will leak. Put the gasket and thermostat in, put the housing back on and remember not to over-torque the bolts or when the engine gets hot bad things will happen. Replace the hose (is it time for a new one anyway?) and then refill the cooling system with antifreeze. Start the car and check for leaks.
