    i really wish these fans were dependable........ they do free up horse power and run really quiet... but they burn out and seize up and leave you stranded.... mechanical is the way to go for dependability

    Are you running the BMW 195*/210* sensor?? not sure to put a 180* t stat in or keep my 195* in because i thought we were supposed to run the t stat lower then when the fan low kicks on??

    Yes I’m running the BMW sensor. I had the 180 thermostat and the engine never git warm enough to hit the optimal operating temp. So I swapped back to the 195. Now it gets plenty warm enough. I see get to just below 210 and then goes down and stays right around the 200 area like it should.
