I have a 2006 Kia Rio 1.6L. Yesterday I put in chemical flush in the coolant reservoir since I’m flushing the system out on the weekend. I drove it once yesterday and the temperature increased as normal. Today when I drove it, the temperature was still at C after about 5 minutes, after about 20 minutes of driving, the engine finally got up to near normal operation temperature. What could the cause of this be?

The only thing that can cause slow warm up is a stuck open or missing thermostat. Change the thermostat and all will be well.
