Do the following exactly as stated, i think u have air in the system.

The generic method of bleeding air from the cooling system is to use a floor jack and raise the front of the car as high as poss, then fill the coolant recovery tank full and run the engine until it just starts to overheat, high end of normal zone on gauge, then shut the engine down and run cold water over the radiator core, this will self bleed the system and the coolant will be pulled from the recovery tank, repeat as necessary, never let the recovery tank run dry or more air will be pulled into the cooling systeml , if it still overheats then you need to have the head gaskets checked with a gas analyzer for hydrocarbons present in the radiator or recovery tank

no heat engine running hot sound like faulty thermostat which is sticking closed.if thermostat stuck closed no coolant can circulate through the engine block and radiator causing no heat condition and engine overheating.replace thermostat and radiator pressure or surge tank over jug cap see what happens.

I have just picked up my kia Sedona from the Garage after having a refurbuished engine put in due to a blown Head gasket. Ran it on the motor way and the temperature gauge shot up to "H". I...

in my experience i would have just changed the head gasket instead of putting in a new motor

anyway there could be an air pocket in the engine or rad what i would do is

1 drain the rad by drain plug located at the bottom of rad on left or right side looks like a valve
2 start the car and slowly add 50/50 antifreeze to the rad
3 once rad is full open and fill coolant bottle
4 watch temp to see if it goes up to the high mark

if this does not help I recommend taken the car back to the place you took it to get fixed could be a head gasket problem

06 Kia Sedona overheats when ac is on. If the ac is off the van will return to normal temps. Had the compressor just replaced and v-belt. Both fans appear to be running when ac is on.

Does the engine over heat or the gauge goes to hot. Really hot. Since the A/C is on , this puts an extra load on the engine. This is why the fans come on when the A/C is turned on. This is usually low speed fan mode. High speed doesn't come on untilll 220 to 230 degrees. Most vehicles. Cars don't over heat untill the gauge gets in the red, when it starts getting close is time to worry and stop. I guess the question to you would be, What does the temp gauge read?

My kia van hardly has any heat but the temprature gage says normal whats going on

The first thing you should do is to check your coolant level and check for leaks. I assume you mean the internal heater isn't getting very hot-If the temp gauge is reading correctly and there is no engine overheating then the thermostat and radiator is working correctly, so if the coolant level is OK there is either an airlock or the heater matrix is blocked or the heater valve is not opening. You will need to have the system pressure tested at a garage. In any event it will probably need to be drained to fix the problem. I hope I have been of help but please do not hesitate to ask if you have any further questions.

2005 Kia Sedona...begins to overheat in slow traffic

I would check to see if the radiator fans are coming on. Also check the freon pressure in the A/C system.
