2016 Hyundai Elantra overheats when driving but not when idling
My car just recently started overheating on my way to
work the other morning. It will get all the way to hot but
when I slow down the temperature will go back down. I did
need some coolant so that was added but still is
happening. I let it sit and idle today for at least 10 mins
while we were checking the thermostat, never even got up
fully to the halfway mark while idling. Rode 2 minutes
down the road and it immediately overheat. Open to any
suggestions! No leaking from what we can tell
