If you want to get rid of the mechanical fan and go to an electric, this is the ticket. Made of .062" aluminum, these shrouds have a wide lip to allow you to trim and fit most applications. Measure your radiator core from the inside edge to the inside edge of the tanks and then measure the core the other way. (The tanks are not included in the measurement.)
Shrouds without fans available (at right). Control and wiring sold separately.
