Running hot

So what car ? Engine ? Exhaust ? Bottled up exhaust can cause overheating.
Grasping at straws now and thinking about some of the KRAZY cooling problems I've seen over the years. One aluminum water pump with a bubble like slag left in the lower hose casting (just a bad part). Then caps from anitfreeze bottles obstructing flow, thermostats upside down, on and on.
I wish you good luck.
