Just curious; has anyone either altered the temp setting on the cooling fan or installed a swith to control on/off cycles? I have yet to observe it come on, yet did a voltage and ohm test with possitive results. My other thought is that if used with switch, it could be ducted to flow across the headers and reduce radiant heat. I live in S. FL and it gets hot from May through October, real hot! The passenger side vent and fan could reduce the engine bay heat substanially in city driving although it may be moot on the highway. Any thoughts?
