Reply to "Radiator coolant flow direction"

Various Factory literature shows it both ways, which was a bit confusing. So on a 550-mile trip to a 'Vegas Fun Rally and back some years ago, I tried it both ways in our '72, changing over at a racing friend's home in Pahrunp, NV.

The car ran the same temps both ways and the trip each way was long enough to fully assess any problems. Including past Marlin-Jacks home in the southern NV  desert.  So based on that I'd say the routing makes no difference in a street Pantera. YMMV-
