There is an adjuster knob up top with a blue mark on it. The previous owner told me to keep it on this mark and it should run at 180 degrees. I watch it close as the weather warms up.
Thanks for the feedback its reassurring to hear others with a similar set-up. I am just getting back in to owning an older truck and was not familiar with the concept of an electric fan replacement and not sure if it was supposed to be pushing or pulling the air. Thanks again.
