just wanted to know cause im in the process of replacing my radiator. and i wanna drain all my coolant also and put fresh coolant in.

What i was goin to do:
1: diconnect radiator lower hose and upper hose let it drain
2: replace radiator and radiator hoses and also replace thermostat


How do i drain the coolant inside the engine and how to do it safely?

I tried going to kia-techinfo thing but that websote do not work for me on my work comp or personal laptop. i have the latest and greatest window 7 ultimate and latest firefox and internet explorer browser but still dont work.

Can anyone copy and paste it on here? Instruction on how to properly replace engine coolant and radiator.

Thanks in advance

There is a drain plug on the bottom of the rad. You can use a garden hose to "flush" the coolant in the engine. Drain the rad, put the hose in the filler neck, start the engine, and let the water flow through the engine until you see nice clean water comming out the bottom of the rad.

so your saying is run a water hose on the top cap of the radiator open the drain plug for the radiatorand let the car run until i see clear water go thru the whole system? do i do the same puttin antifreeze in? and how much can the spectra hold. and also it recomends in the manual to not use tap water straight because it might cause of the bleach in regualr tap water.i guess i have no other choice but to do that then.

If your going to do the flush, I would take off the lower rad hose to let the water get out faster. When you fill the rad back up after use a 50/50 mix of coolant and distilled water. Your Kia should hold about 1-1/2 to 2 gallons of coolant/water mix. It should not take long to run the water through your engine. Keep a eye on everything, you do not want to overheat your engine.
