Gets hot and stalls out

Understood. I’ve got a mechanical fan on the car; maybe I need to look into a high volume pump. I know the modern cars run at 210 and are fine with it, but I’ve always thought that to be an apples-to-oranges comparison. Plus (to be honest) I’ve already melted down one motor so I’m hypersensitive to temps.

They run them that hot for emissions. It's not for power or anything else.

Guys claiming 210 isn't too hot are sadly mistaken.
