Question about 2000 Kia Sephia

1 Answer

The engine is overheating even though there's still coolant in it and there doesn't appear to be any leaks. There is some rust in the radiator and have flushed a lot of it out. Could it be the thermostat or something else?

Hi have you checked to see if the cooler fan is running when it gets to normal running temperature? if not running, first check fuses, then check wires connected to the fan switch ( located on bottom or on side of radiator ) spin fan to make sure it has not seized it should move freely, to check if it is thermostat, after running engine for a few minuets feel the top and bottom hoses to the radiator, if one is cold and the other is hot ( normally bottom is hot, top is cooler ) then the thermostat will need replacing, and finally ( last check ) remove the oil filler cap and see if there is a creamy residue on it, also check engine oil as well to see if it is similar in colour to the cap if it is your head gasket has blown and will need sorting ( very rare )....hope this helps please vote thanks

Why did my 2011 DTS Cadillac overheat?


An overheated engine can be caused by anything that decreases the cooling system's ability to absorb, transport and dissipate heat; therefore engines can overheat for a variety of reasons. Let's take a look at some of the most common causes.
Cooling System Leaks
This is the primary cause of engine overheating. Possible leak points include hoses, the radiator, water pump, thermostat housing, heater core, head gasket, freeze plugs, automatic transmission oil cooler, cylinder heads and block. Perform a pressure test. A leak-free system should hold pressure for at least one minute.
Wrong Coolant Concentration
Be sure to use the coolant recommended by your vehicle's manufacturer. The wrong type of coolant and/or mixing the incorrect concentration of coolant and distilled water can also result in engine overheating. The best bet is to perform a complete flush and fill.
Bad Thermostat
A thermostat is a heat-sensitive valve that opens and closes in response to engine temperature. Heated engine coolant passes through to the radiator when the thermostat is in the open position. In the closed position, it prevents the flow of coolant to speed up the warming of a cold engine. When the thermostat gets stuck in the closed position, coolant stays in the engine and quickly becomes overheated, resulting in engine overheating.
Blocked Coolant Passageways
Rust, dirt and sediment can all block or greatly impede the flow of coolant through the cooling system. This can limit the system's ability to control engine temperature, which may result in higher operating temperatures and engine overheating. Once again, a flush and fill is recommended to remove debris.
Faulty Radiator
By passing through a series of tubes and fins, coolant temperature is reduced in the radiator. Leaks and clogging are some of the most common causes of radiator failure. Any disruption in the radiator's function can lead to elevated engine temperature and overheating.
Worn/Burst Hoses
A hose that contains visual cracks or holes, or has burst will result in leaks and disrupt the flow of engine coolant. This can result in overheating.
Bad Radiator Fan
A fan blows air across the radiator fins to assist in reducing the temperature of the coolant. A fan that wobbles, spins freely when the engine is off, or has broken shrouds will not be able to reduce the temperature to proper level, thus possibly resulting in engine overheating.
Loose or Broken Belt
A belt is often the driving link that turns the water pump at the correct speed for proper coolant flow through the cooling system. If a belt is loose or broken, it cannot maintain the proper speed, thus resulting in poor coolant flow and ultimately, engine overheating.
Faulty Water Pump
Known as the 'heart' of the cooling system, the water pump is responsible for pressurizing and propelling engine coolant through the cooling system. Any malfunction of the water pump, including eroded impeller vanes, seepage or wobble in the pump shaft, can prevent adequate coolant flow and result in engine overheating.

My kia sedona 2003 is overheating is it the water pump


Probably not the water pump. The most common cause is rusted out/leaking underbody heater rear heater lines. The steel portions of the lines rust and leak coolant. The low coolant level will cause the engine to overheat. If overheated repeatedly these engines will usually warp the cylinder heads. This will cause severe overheating and may damage the radiator and other components due to combustion gasses entering the cooling system. A cooling system pressure test should be done to check for external leaks, and a block test can be done to check for the presence of combustion gasses entering the cooling system.Make sure to check coolant level in the radiator when cold, NOT in the reservoir on the inner fender. This could also be caused by something as simple as a thermostat or radiator fans that aren't working.

2000 pontiac bonneville overheating


Look in the radiator to determine if the brown stuff is rust or oil. If it's oil then the head gaskets are blown and the heads will have to go to a machine shop to be ground flat. Do them both even if one side is ok, or the engine will never idle right. If it's just rust, install a back flush kit and blow out the rust. Turn the heater on when you back flush to get the rust out of the heater core. Replace the thermostat and anti freeze. Pressurize the radiator and make sure it holds. If the pressure drops off then look to find where the leak is (head gaskets)

2002 Intrepid cam sensor was replaced - now engine overheats. No evidence of leaks or coolant pump failure. Please advise.


Hello and welcome to FixYa! If you have overheating problem, it can lead to multipleissues. You may be running on low coolant that's why the vehicle overheats. Ifthat's the case, please add coolant and make sure that it sits on the rightlevel, too much coolant can cause overheating too for coolant will overflow. The vehicle may have a faulty or worn out radiator blowermotor that's why it overheats. If that's the case then you will need a blowermotor replacement to resolve the issue. If the radiator is clogged with dirt and rusts this issueoccurs too. The coolant doesn't flow normally on the cooling system if it'sclogged. If that's the case, I strongly suggest that you have the radiatorflushed to drain out dirt and rusts. If you think that the radiator served youenough then it's better to have it replaced. Please do check the radiator hoses, If you have worn outhoses it can cause coolant leakage which can result to overheating. A tiny holeis good enough for the vehicle to overheat. A faulty thermostat sensor can cause the issue too. If youhave worn out thermostat, the fan may not trigger that's why the fan won't workwhen under stressed conditions. A blown radiator blower fuse can cause thisissue too so I suggest that you check the radiator blower fuse and replace itwhen necessary. What causes the radiator blower fan fuse to blow? It's becauseof a failing radiator blower motor, If that's the case have the radiator blowerfan motor replaced. If the fluid in radiator doesn't circulate then it meansthat you have a blown head gasket or a faulty water pump. I suggest that you gofor the water pump replacement first specially if you think that it's near theend of it's service life. Usually, water pops out the radiator when engine isreved (a sign of faulty water pump and possible blown head gasket). Hope you find this information helpful enough and thank youfor using FixYa! Have a good one!

Engine over heated stalled out and will not start


FIRST OF ALL CHECK ENGINE COOLANT LEVEL IF LOW YOU NEED ADD MORE COOLANT CHECK FOR LEAKING TOP AND BOTTOM RADIATOR HOSES, CHECK RADIATOR FOR LEAKS. IF YOU DID NOT LOSE MUCH COOLANT THERMOSTAT COULD BE STUCK CLOSED.WHEN ADD COOLANT CRANK VECHICLE AGAIN CHECK BOTH RADIATOR HOSES THEY BOTH SHOULD BE HOT. IF TOP RADIATOR HOSE GOING TO ENGINE BLOCK COLD AND BOTTOM RADIATOR HOSE COLD WARM THE THERMOSTAT IS STUCK CLOSED. IF ENGINE OVERHEATING WHILE SITTING IN LONG TRAFFIC LINE YOU COULD HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR.IT CONTROLS COOLANT FAN AT SET TEMPERATURE.IF COOLANTS FAN NOT RUNNING WHEN OVERHEATING.EITHER COOLANT FAN FUSE RELAY FAULTY OR FAN MOTOR DEFECTIVE OR FAN MOTOR WIRING CONNECTOR HAVE BROKE WIRES.IF COOLANT FAN IS RUNNING WHILE ENGINE OVERHEATING CHECK CRANK OIL AT OIL DIP STICK OIL LOOKS LIKE MILK SHAKE YOU HAVE BLOWED HEAD GASKET. WARNING DONT KEEP DRIVING VECHICLE WHEN ENGINE OVERHEATING YOU WILL CAUSE ENGINE AND TRANSMISSION DAMAGE.

Engine heat keeps going up even after refilling coolant.


are you leaking coolant ? or you were just low and added fluid to it ? if your car is full of coolant and still overheating change the thermostat first its the cheapest and easiest starting point.

If that does not work i would replaced the coolant temp sensor pretty cheap to that tells the ecu when to turn of your electric fan assuming you have a electric fan.

if you have a clutch fan aka belt driven you may need to replace the fan clutch its basiclly a unit that expands and contrancts a spring to turn fan off and on.

if none of the above work you probably have a faulty water pump even though its not leaking the propeller blade inside is likely rusted and limited functionallity


if this helps you please give me a good rating

could be a couple of things your thermostat could be faulty or sticking.your radiator or heater core could be getting plugged up to where theres not enough flow or your water pump is goin and last but id check first your belt need to be tighter could be slippin or one more your fan clutch which is just behing the fan could be weak an not driving the fan hard enough.
