Hi Kia Forte 2.0 owners,

I would like to ask some questions regarding the radiator system in our Kia Forte 2.0 SX. Recently I had problems with the radiator and has to change the radiator panel. Didn't do it at a Kia service center. After change seems like working ok for a while. But when I check the water level in the coolant reservoir it seems to drop below full every couple or weeks. Brought back to workshop they cannot find what's wrong. Lately I also check the radiator itself. I would pop the radiator cap in the morning before starting the car. I cannot see water inside, so I pour water inside and the water will slowly go down. I can pour up to half a bottle of a 1.5 L mineral water bottle. But all along the level on the coolant reservoir still remain at Full. My question is should we be concern that the radiator need to top up water even if the coolant reservoir is indicated as full. From what i read in youtube we only supposed to top coolant in the coolant reservoir. Hope to hear some of your experiences with the Kia Forte radiator system. Thank you.
