This is a radiator in a 1961 Ford Galaxie that needs a fan shroud. Start by measuring all of the dimensions, taking care to think about how the shroud will attach to the radiator, if there are any obstructions you need to take into consideration, how far away the fan is from the radiator and if there are any angles or off center components. This fan is off center towards the passenger side by about 1/2 inch, sets back about 1 3/8" ,and it swings about 1" above the top of the radiator. It is parallel with the radiator, and there are no hoses or other obstructions to deal with on this particular project. | This is a radiator in a 1961 Ford Galaxie that needs a fan shroud.

Polyvinyl alcohol, or "PVA", is a water-soluble plastic commonly used as a release agent for molds. Using PVA will make removing the foam much easier after the part is laid up. |
