WHere do you live? What is the outside temperature? Yes begin by simply removing the thermostat....open, remove and close: this will make or break the thermostat hypothesis. There are other more severe causes that would keep the temp high even without a thermostat....like a blown head gasket...but it is not a common issue with the Sporty: there are a few cases, but not a common syndrome like the GM3.4
OBviously your alternator does not deliver high amps and is overloaded by heavy demand....again I'd check alternator belt for wear and tightness. I think it slips. Otherwise, the built in regulator can be shot...go with the belt first. If it pulses like you say, then voltage goes up and down...and a common electrician multimeter , digital or needle type, 20$ range, will simply confirm....but then even the steady state voltage could be interesting if tightening (changing) the belt does not cure the problem. NOrmal voltage when engine runs should be 14.1 - 14.7

I have a 2001 sportage, there is no power it feels like it is running out of gas. I have just replaced the air filter, coil, sparkplugs, timing belt, water pump, fuel filter and then had to change the battery. Could this be the fuel pump and if so is there a way to check prior to purchasing a new one.
...had to change the battery....??? why?
WHen voltage runs low (for alternator problem) engine starts being erratic : injectors do not fire, spark is poor, ..and battery runs down. Test voltage (14.2-14.7)
(if that was original battery....it was expected death).
Testing for fuel pressure at fuel rail (40 psi) will make the point about fuel pump....
don't change the fuel pump just for testing!
There have been cases of blocked catalyser....again do not change a catalyser just for testing....disconnect exhaust and run a test with a lot of noise....(That's fun)...

I live in ohio and it was actually in theh 40's last night when it started. then today the temp has dropped drastically and is expected to drop more tomorrow. How would i know if the head gasket was blown? I also went to the part store and bought a new thermostat however, i have to wait til tomorrow to replace it due to the fact they did not have the gasket in.
I will also tomorrow check on the belt and see if it is loose, if it is is there any certain torque it needs to be set at or should i just tighten it? The as soon as i can get my hands on a multimeter i will check the voltage. now would i stick both the pos and neg in the cig lighter or just the positive?

THe positive probe on center of lighter plug, the negative to any metal part of the body, including the outside ring of the lighter plug. Of course, you can test direct on the battery posts .
BLown gasket will show other signs: heater will provide sporadic heat, temp needle will fluctuate, steaming, having to top off the radiator and coolant tank from time to time....
Removing the radiator cap and running engine after topping off the rad if necessary could show gaz bubbles coming out (that is exhaust leaking into the cooling system). A few "air" bubbles to begin with is not a concern but a gasket leak can give a regular outpour of bubbles.

The battery was approx a year old but had to be replaces because it went dead and it was -33 and froze, prior to that happening the battery was fine. Do you know if there is a shrader valve on the fuel rail.

Hi i have one more question i replaced the thermostat today and i noticed that there was coolant leaking from the casing before i actually replaced it. Now my question would be when i start the car with the radiator cap off the water does not get sucked down. It actually shoots up real quick then just goes back to the original resting place. Also after driving the guage once again started shooting up towards the H, but was easier to regulate with the heater.What could this be?
Thanks again stressed out kia owner

I'm afraid it generates a gaz bubble taht escapes at start up then additional gaz can escape without showing bubbles as the level is down. Do that again but once it "goes back to original resting place", keep it running and top off to the rim with coolant to see if gas bubbles escape.
DO you have coolant left in the reserve tank?

YOur question tells you know what is involved....I have NOT ckecked myself...just assumed there is one like my other car....I will try to locate it and return....

Ok i have another quick question there are not really bubbles coming out but it looks like there is something coming to the top. And i actually only have alittel coolant in the reserve tank. Would a blown head gasket cause the ater not to circulate threw the engine? I am just getting really frustrated with this car as i have never had so many problems with a car. It seems as it is one thing after another.

No bubbles is a good sign...and while a few isolate cases were reported, this engine type really does not have a bad history of blown gasket .
I understand you have changed the thermostat....
ANd yes, exhaust invasion will impair coolant circulation but I'm still not committed to that explanation without further signs. WHen you use the heater DO you have a steady heat flow coming from the heater or are there times at which no heat comes??
Apart from hte needle that goes up, are there other signs of overheating? Steaming?
One test I used to test gasket leak is applying compressed air to spark plug hole, after rotating the engine so the valves to that cylinder are closed. COMpressed air will try to push piston so it must be really at the top . IF there is a leak on one cylinder, the air will go to cooling circuit and bubbleup at the radiator cap.
