Question about 2002 Kia Sportage
My 2002 Kia Sportage overheats. I have replaced the Thermostat, sensors, hoses and radiator and it still overheats in stop and go traffic. If I drive down the street at 40 miles per hour or faster, it won't overheat. Could it be the water pump or should I search for a less costly and less intrusive fix. PLEASE Advise.

Unfortunately, I refer to repairs of this type as "search and repair missions"...You've overlooked the radiator core...the only thing left and probably the culprit. ($180)

if your vehicle has electric fans they may not be working you need to check that they are working let the motor idle until it starts to overheat & see if the fans are working ,if not check for blown fuse,or loose wiring connections,it could also be the temperature sensor that activates the fans,it may be faulty......hope this helps.....sherrs

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