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.

Hi yes i actually have steady heat i have never noticed a time when it gets cold at all. And it has never steamed or overheated just the guage goes up. But there is no circulation of the fluids. that is what confuses me.
Now by compressed air do you mean canned air or the air i would use to blo up a tirer on the car?

Ok i also had another question about the lights in my car i noticed tonight that half of my dash lights (the side where the fuel gauge and temp guage are) and the radio buttons will go off and come back on once in a blue moon. Would this be caused by a bad ground? and if so do you have a wiring diagram for the vehicle? cause i would really like to get that fixed as well.. i also encountered the check engine light today while driving when i got the code checked it wwas 90442 something about the fuel cap i made sure it was all the way on and the light is still on any suggestions there?

Your problem with dash lights might be linked with the high temp indicator. IN fact try one thing: run the car, then run the heater blower at different speeds. Does the temp needle change position instantaneously when you switch the blower on? THis problem was reported several times and seems to be linked with ground problems. SO several have run new ground wires from the battery negative to engine block, firewall, and any visible ground wire. HOwever no one had the clever idea to come back and declare unambiguously if that solved their problem partly or completely or what else they might have done.
FOr diagrams, I can post some but better register yourself to www.kiatechinfo.com and grab everything you want first hand, diagrams, repair manuals, codes....
ANd I talked of compressed air as you use for tires but the more you say, the less I think you might have a gasket problem....and since you say heater works well, I have no doubts you do have water circulation which is rather difficult to observe from the radiator cap.
HOw does the fan behave, specially just after engine is started: normally it runs with a whooshing noise for a few seconds then slowly clutches down...
It might turn out all you have is a false temperature indication....and I wish this is the case....I'd try to use your kitchen candy thermometer in the radiator to have a 2nd temperature opinion....
