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....

Haha so i decided to just drive the car with the heat off until the temp guage went to the top (i also filled up the reseviour) and when i pulled in the drive way it was spewing out the over fill hose and what sounded like it was boiling.. I also added one wire from the negative battery terminal to the frame. and i noticed that both the pos and neg connectors where cracked. I also think whoever put the new battery in put in the wrong size as it was actually pretty tough getting the cables off of it.

Well that sounds more severe indeed.....you cannot fake boiling...ha!
I'd find an air compressor and test as I said. It is just so annoying the plugs are out of easy reach...but it is not such a tedious job anyway. You will have to remove the valve cover.
 
engine
 
THose complaining of fan clutch failure were mostly living in very warm environment and used A/C ; in cool temperatures, highway speed is sufficient even without a fan...
Was the water pump changed at same time as timing belt (I think you said the belt had been changed...right). BUt Water pumps fail for bearings generally and that makes noise and leaks, not boiling.....

Yeah actually the only thing i have replaced was the thermostat. And i took another listen once i sent last post and there was a hissing noise and the water was just rushing back into the overfill tank.. Could the water pump be causing this problem possibly?
And do i have to take all that off just to give it a tune up??

I was questioning the pump , just trying to find a thread where I remember someone said the blades from the water pump had all broken out..but I don't thnk that was in a KIA forum...probably a GM 3.1 or 3.4....so I'd rather dowplay this option.
WHen you say "take all that off to give it a tune"...I suppose y0u mean the valve cover...hey?...well just to change the spark plugs, no. You would need to remove the intake tube and the plastic cover...and then you have the coils and the holes to the spark plugs..the plugs are hidden under down there and you grab them with a plug socket and an extension to your ratchet...
..and possibly, you could apply air to the plug holes .. it is a long reach....but possible...but you would have some problem seeing which piston is at top dead center without seeing the cam position....
THe first time I had to do the spark plugs, I thought it was hell to have to do all of that just to reach the plug...and I still think the same...but in fact, a plug change can be done in just a little more than an hour...and with 8 or 9 extra 10mm bolts, the valve cover is out..and then back in. ANnoying, but easy and straight forward.

...but you did not tell me about the fan....you are sure it has a belt driving it? My son had a similar problem with his NIVA..overheating and alternator failure........just to discover the fan belt was simply gone.....and with all those things around there, it needed to peek intentionally to notice something was missing....
