Fan Clearance between a '95 4.9L & a stock brass 2-core radiator (same thickness as an Aluminum 1-core) in a Bronco/F-series.
The length of the 4.9L I6 engine leaves VERY little room for an electric fan & shroud. This pair might have come from a Contour, Focus, or Escort. A Mark VIII fan doesn't fit, even with the thinnest radiator core.
