Thread: Electric Fan for my 67 Mustang Fastback

Tweet

I'm using a mechanical fan and an electric fan (mounted on the front of my radiator). If I get caught-up driving in traffic with my '53, as in stoplight traffic, the temps start to climb a bit, sometimes 200+ degrees. This is when I switch on the electric fan to flow air through the radiator. This is also on 100 degree temp days as well. When cruising down the road, it just stays pegged at 180. It doesn't do well without airflow. I'm a "Nervous-Nelly" when it comes to underhood temps. I'm also running the big 4-pass "Desert Cooler" US radiator as well. I'm wondering if I'll need the electric fan when the engine gets a few more miles on it than the current 600 miles......just put some more "break-in" miles on it. I also think that when the temps cool down, say below 85 degrees outside, I may get away with not needing it as well. Who knows, I guess I'll find out with experimentation. Just my current situation and setup...
