Captain, I tried this as well as a full dozen other tricks. On a 1200 mile round trip to/from Vegas, I switched the hoses from top-feed to bottom-feed midway. It made zero difference in running engine temps. . In a Pantera, NOTHING made any difference except changing to a Fluidyne aluminum- 21 years ago. Same assembly still working just fine. As Forest said, to a heat exchanger it makes no difference
