What kind of coolant do i use for a 2004 Kia Ria, 50/50 OR 35/65? I live in Alaska. Need an answer asap.

Depends on where you live. 50/50 gets you to - 20 degrees. You live in Florida, use more water. Alaska, use more anti freeze.

Hi it seems the heat sendor switch is malfunctioning . Will be good to run a diagnostic check on ENGINE CONTROL UNIT (ECU .) for conformation of faults .

On these and many other vehicles, use a vacuum refill coolant air lift.This removes all air in the cooling system and then fills the cooling system fully with coolant.

Check this diagram location, Engine Coolant Temperature sensor...

Thank you for using FixYa, have a nice day.

2004 kia sorento, thermostat replaced, all belts, water pump. now there is a coolant leak again, cannot tell where it is coming from. Leaks fairly quickly and overheats within 20 mins. Heat is not working when coolant is not full....could it be the coolant resevoir? head gasket??

did you get all the air out of the coolant lines?
as well check your coolant temp rating depending on where you live ie alaska or texas your mixture of coolant to water ratio could be off

This could be a serious problem. Check your coolant level, then check the rear heater lines that supply coolant to the rear heater. They run under the van, over time they rust and leak. Because it is under and to the rear of the van it is hard to notice, i.e. coolant puddles and smell. But please note that this engine has aluminum cylinder heads and does not take kindly to being overheated.

First check the oil and coolant levels. You may have a broken timing belt. White smoke is usually due to coolant burning in the combustion chamber. (Head gasket)

The most likely cause of your problems is a bad master cylinder. If you have had any recent brake work done then it could just be air in the system.
