By kansas - 15 Years Ago Im going to add a/c to my 55 vic with 292 auto  this winter/ I also would like to do remove the steel fan and just run the electric/ it has to be a pusher / ? is whats cfm do I need also if you have done this what brand fan , any over heating problems with just the pusher? By Pete 55Tbird - 15 Years Ago To run an electric fan as a pusher you will need 2500CFM or so. This will require a 12Volt alternator of at least 100 amps. Look at the late 80`s Ford Taurus with the 3.8 engine. You should keep the engine driven fan. Use google to find more info. Pete By rick55 - 15 Years Ago I have been down the road of an electric fan and though they can help to cool, my experience is that the motor driven fan is still the best. Pusher fans do not work as effectively as pullers - your terminology not mine. This I thought was due to the restriction the fan causes by being in front of the radiator and also the heat it generates whilst running. I found that later model multiblade fans were much better than the standard units fitted to our engines. Here in Oz our late 70's/early 80's Fords (running Cleveland 302/351) used a 7 blade flex fan which will bolt straight onto the water pump mounting flange. A much better option than the US 3 or 4 blade steel fan and poses no clearance issues. This with a pusher electric fan controlled thermostatically worked perfectly for me in the hottest of days - up to 47degrees Celsius (about 44 or 45 degrees Fahrenheit). I hope this is of help regards By kansas - 15 Years Ago what the deal is Im going to the cruisin the coast down on  the gulf which is a week long car show in oct  with a 29 mile cruise which I know with the slow speed and A/T  over heating could be a big problem/ The people that I have talked to that have been there say that a electric fan is a must/also going to put  A/C this winter By charliemccraney - 15 Years Ago A 29 mile cruise can't be any worse than light traffic. Does it overheat in light traffic? I think electric will be more than adequate, they've been used in production vehicles for some time now, but if doing away with the mechanical fan, go with dual electric fans. Mechanical fans don't really break; typically, if they do, there are bigger problems. Electric fans quit without warning. Having two ensures that there will be some cooling if the other fails, and should give you reasonable time to notice. By YellowWing - 15 Years Ago I went to install My new U.S. Radiator 3 row high efficiency radiator with built in puller fan and shroud today. Unfortunately it does not fit. I will modify tomorrow and mount the fan without the shroud, it will just fit in a puller application. Will let you know how it works out. Mike By kansas - 15 Years Ago were fine in slow traffic its the stop and go if its over 90 that cause me trouble
