Ka running hot, but not overheating.

He is definitely correct, when I originally bought my car it had a stock automatic KA, I never could figure out why it would always go to hot when stopped then when cruising it would go under operating temps and would never regulate temperature properly. Well come to find out previous owner took out the t stat, which caused a leaking headgasket and fried piston rings which resulted in me getting a SR.

I would def get a Nismo or OEM T stat because I tried autozone and o Rielly's they never worked properly. Just make you you install it properly. If the t stat doesn't fix it I would def look for a H Gasket leak.
