Overheating issues

Hey. Flex fan is problematic. As stated. Lower hose collapsing might be an issue. Water pump might be as well. Really need temp top and bottom to see what the drop in temp is. Tells you if Rad is cooling correctly. Myself, I would ditch the aluminum Rad for a Big block A body Mopar factory rad. Copper and brass. IF the Rad is not cooling. BUT the flex fan for sure should be replaced....in any case. IMO. Could be timing, or Carb running lean.
