An faulty thermostat will make the car boil but the water will normally go to the resevoir bottle. I be checking for burst radiator hose or cracked top tank before anything else. Thermostats are c;osed when the engine is cold and as the water heats up they open and allow water to pass through the radiator to cool. Coolant over the engine means boiling and escaping through an opening (hose,tank punctured radiator etc)

Location of the engine diagram for a 2000 Buick Century. The engine has overheated when the coolant reservoir has water still in it.


On a cold engine, remove radiator cap, where applicable, is there coolant in the radiator? Usually the reservoir has cold and hot coolant levels marked on it. If it got too hot that reservoir would fill up in a hurry. When it got hot, what was the temp reading in degrees F? When it got hot, was the radiator fan running?
If your thinking thermostat, the engine side of upper radiator hose, should go to thermostat housing. Have to remove thermostat housing to get at thermostat.
Any applicable trouble codes? Some of the national brand auto stores will check po codes for free or use an obd2 code reader to check codes, yourself. There could be other issues, coolant temp sensor, gasket problem--if combustion gases in the coolant.

Tempurture gauge goes from normal to hot then back to normal replace thermostat already and still doing the same thing


-You could have an air pocket trapped in the engine. Look for an air bleed valve on or around the thermostat housing. Crack it open with engine running until only coolant, no air, is expelled. If none, take off the radiator cap (not while engine is hot, though) and run the engine until the thermostat opens and hot coolant begins circulating through the radiator. Shut off engine and put the cap back on. That should expel any air that was trapped. If it continues going hot and normal on the gauge, try replacing the temp sender unit. Also make sure coolant system is full, that includes the overflow tank.

Will not have a thermastat make suv overheat its 2001 ford escape


No.
Leaving the thermostat out will not make the engine run hot.
Some possible causes are low coolant, faulty water pump, or leaking head gasket.

Cooling fan runs intermittently and causes the engine to run hot


The cooling fan isn't causing the engine to run hot, it's electrical and cannot heat an engine. It is turning on in response to your engine running hot. Check coolant level and age, if it's still running hot then check the thermostat - it could be stuck closed. If the thermostat is fine and coolant level is full, it could be partially clogged radiator or head gasket problem (a sure sign of bad head gasket is that your coolant keeps disappearing with no leaks).

I just replaced my water pump and my car runs hot, right now there is no thermostat in the car and it still runs hot, what could be the problem


I bet it does run hot, a thermostat has two functions, to bring the coolant to operating temp and to regulate the flow of coolant thru the system, If the coolant runs to fast thru the radiator it will not be cool enough, engine will over heat, check that the fans are working, have you flushed the radiator, is the radiator flowing?

Tempeture guage not working and heater is blowing out very little hot air on my ford galaxy


you need to get the thermostat changed. The thermostat controls how much coolant runs around the engine and sends signals to your temp gauge to indicate how hot the engine is.
if the thermostat is faulty it wont sent signals to the temp gauge and wont open up to allow coolant to run around the system. Your heating is run by coolant, behind the dash there is the heater matrix hot coolant runs into the matrix which gets blown inside the cab.
Fitting a new thermostat will fix all the heating and gauge problems. if your technical minded you can buy a thermostat from an autofactor (or ford, but they are expensive from ford). a garage will charge about £30-£100 ish for a new one.

hope this helps :-)
