| RE: Electric Fan for my Big Block |

| The SUMMITT catalog offers many options. The trick really isn't the fan, nor the temp switch, not the manual override switch, it's what do you do with the waterpump pulley? Using just bolts and washers on the stamped steel pulley against the waterpump flange will likely lead to the pulley getting stress cracks from the flexing it will do. I soled this by maching a 1/4" aluminum ring with 4 bolt holes in it plus a center hole. Works great. Another idea is to use a machined aluminum (or steel) pulley, such as March manufactures. Many electric fans simply mount agsint the rad fins with sort of tie wrap thingies that go between the fins to the other side of the rad where rubber and plastic washers are used togher with the one way tie-wrap fasteners...easy installation. |
