New to this site...but hoping to get pointed in the right direction.
Got the above light on a 100 degree day.
Shut it down immediately....and let it cool off. Started up and moved on down the road...temp stayed down. Now, when I sit for to long...(drive thru)...temp guage starts to slowly rise.
What could this be? Haven't checked the fluids personally yet...but trusted fellow who did for me.
