Engine Mechanical problem
2004 Kia Optima 4 cyl Two Wheel Drive Automatic 83000 miles
----------------------------------------------------------------
I have a 2004 Kia Optima that occasionally tends to overheat (approaches red) with the ac on. Will cool down after the ac is turned off. I've changed the water pump, thermostat, and flushed the radiator. Both radiator fans are working, and no hoses are collapsing.
I just got this car and don't know if this is normal for Kia's (an engineering defect?).
Any idea's? Anyone else having this problem?
