oil

I had the same problem when I tried 20w-50 in a Subaru. The oil is too thick. Drain it out and use the recommended weight for the Kia.

Well, it didn't start to make noise until you installed the incorrect viscosity oil, so I'm going to guess that the oil is the cause, not the tensioner. If you leave the incorrect oil it, you could end up damaging the tensioner and other components.

Upper value of oil grade has nothing to do with outside temperature. Engine runs at constant high temperature of about 90°C. Grade depends on engine type and is recommended by maker. Most modern engines require 20 or 30 Grade oil. Older engines or worn engines might need 50 Grade.

Lower value (e.g. 20W) is where you might need to tailor the oil to your outside temperature. Oil needs to be relatively "thin" at start-up so that parts are adequately lubricated. Cold countries (USA/UK) usually require 0W or 5W. Hot countries (Australia/Middle East) require 10W. Here in Nth Queensland, where temperatures range from 15° to 40°C, we use 10W30 as recommended by KIA dealers. Caltex Havoline Premium Plus or Castrol Magnatec are often used by KIA dealers.
