Question about 2001 Kia Rio

1 Answer

Kia Rio overheating although everything seems ok

My 2003 Kia Rio keeps overheating. It seems to happen when I am at a standstill and have the a/c on. I've checked the fan, it comes on. I've changed the thermostat. Coolant level is fine. Coolant appears to be circulating. This problem does not always happen, but happens enough to be a problem.

    Would it be so inconsistent?

Possible early signs of a water pump problem. A failing waterpump will circulate coolent when the RPMS are high but when you slow down, so does the waterpump, thereby causing overheating.

    If it's happening when you come to a stop and the AC is on, it's sounds pretty regular. You can also check the serpentine belt for wear. A slick or broken serpentine belt will tend to slip at times, which could be contributing to your problem.

My 2004 kia rio its overheting just when i stop


Check that the fan is starting and working OK. When you drive the air hitting the front of the radiator may compensate a malfunctioning fan. When you stop without the fan working the radiator gets hotter and your dash tells you that there is overheating.

If the fan is working replace the thermostat that may be starting the fan too late. Also check fan fuse and relay.

Do not drive the car in this conditions. Overheating can easily cause damage to the head gasket. An head gasket problem will require a more expensive repair.

My check engine light in my 2003 Kia Rio keeps coming on. So far, my mechanic has pulled codes for and repaired the following. A flex hose pipe, the 02 sensor, pin holes in the exhaust, the gas tank and...

1st of all did your gas mileage drop? If It's an O2 sensor your gas mileage will be about half. If the car is running normally but you can't get the check engine Light off, It may be Simple. Most cars these days have an Oil Life Sensor that needs to be reset after Oil Changes. Turn your Key On , But Do not START. Pump your Accelerator to the Floor 3 Times In 10 Seconds and turn the key off. Start It up Again And See if that was it.

there are 2 fans. one in front and one behind radiator.the front one is for a/c equipped cars only and only runs when a/c or defroster is on. the engine cooling fan comes on only when temp reaches around 210 degrees didnt say anything about overheating so i assume you may not understand how they work
