Inadequate interior heating

Maybe the thermostat is not opening up fully and restricting water flow. The heater core may have blockages - the heater valve is only opening partially. Gotta check out.

When cold weather warming up car takes a long time to heat up blows out cold air then after you drive for a while it warms up

sounds like the thermostat might be stuck open. the engine uses hot antifreeze to heat up the inside of the car if the thermostat is stuck open all of the antifreeze will be circulating all the time and it will take a long time to heat up. I would try to replace the thermostat

Just replaced my thermostat on 2004 Impala. Temperature guage goes from cold to hot then goes back down. Heat seems to work when the temperature guage is lower but as soon as it goes up the heat turns...

i going to assume you have the 3.4L or 3.8 L motor
these motors are notorious for trapping air in coolant system
which sounds like what your problem is
not a problem tho they have bleeder screw built into them
there should be one or two bleeders (depending on model year and motor size)
i think yours should have two
one should be on top of thermostat housing
other one right above water pump on bypass tube
open one bleeder at time with motor running until u see just water and no air
repeat with other bleeder
continue to work back and forth between the two bleeders until thermostat opens
then work back and forth a couple times after thermostat opens
keep checking radiator add coolant as needed

Car seems to be heating up dont know if it can be a stuck or bad thermostat

thats a good possibility, though most thermostats get stuck open, not closed. check the coolant level to make sure its ok, a lot of times the water pump will go bad, and allow air to seep in causing air pockets, thus making the vehicle overheat, also is it blowing good heat?? might be heater core leaking.

Sounds like the thermostat is failing.

Thermostats fail in 2 ways: (a) sticking open (b) stick closed

Your seems to be sticking open - and so the engine warms up VERY slowly,
but still throws a little heat out the vents - less heat over time so that
your daughter didn't even notice the gradual decrease over time.

If you can replace the thermostat on your own, your cost may be less than $5.
To get a new thermostat (always buy parts on your own - the garage will charge a
50% surcharge on any parts they have to locate for your car), try Wal-mart first
(they sell a few thermostats for a few cars), then any auto parts place.

Replacing a thermostat in a 1998 Fiesta ZTEC engine should be the first thing
a DIY mechanic learns after figuring out how to do regular maintenance items - since
stuff like distributor cap/ distributor rotor/ thermostat are actually regular maintanance
items - destined to have a limited life span, like any moving part.

Your thermostat is probably stuck open, not allowing the engine to warm up to its normal operating temperature. The coolant circulates all the time, so the radiator is constantly dumping all of that heat. Replace the thermostat, and your problem should get better. You may even consider installing a higher temperature thermostat if you live in a colder climate.

Overheating Thunderbird

The first thing to do is have is the radiator cap checked, if it's alright then check to see if the thermostat is opening. You will need to remove the thermostat housing to remove it. The temperature the thermostat is suppose to open at is stamp on it. Heat a pan of water a few degrees above what it is suppose to open at and put the thermostat in to see if it opens,
