What can cause “hot coolant” light to come on?
Hot coolant warning came on after idling for a few minutes on a
drive-thru.
Turned it off and then back on after a few minutes and the
warning
disappeared and temp gauge was down to within normal range
and as soon
as I start driving it goes down to the middle. It has happened a
couple of
times now but not every time it’s idling. What can be the cause?
