How To Replace The Thermostat On A Kia Soul or Forte P0128

[@ayanashaw3106]

Do you need to flush the coolant at all or is just draining and refilling it okay?

@@ayanashaw3106 flushing it is a good preventative maintenance.

@@GrimRepair So I have to drain the coolant to replace thermostat? Or can I by pass that process?

I thought you’d have to drop the alternator?

@ So the thermostat in my 2021 Kia is assessable without dropping alternator? I have to replace mine soon. Also draining the coolant is only a maintenance prevention thing, I don’t have to necessarily to complete the job?

@@bayouboy2921 you will make a bigger mess if you don't drain it, because it's all going to dump out at the thermostat. If it gets on the pulleys they may start squeaking.
