1600 FAN SHROUD INFORMATION

....

....

A fan shroud is essential to pull the maximum amount of cold air THROUGH the radiator (not around it). Information applies to USA cars, other countries may vary. For example in most other countries the early style fan/radiator/alternator/waterpump etc were retained through 1970.

There are a few variations on fan shrouds. The shrouds and their matching radiators have various bolt patterns and the bolt pattern can be in a different position relative to the center of the radiator (LHD RHD) A lot of cars have had the radiators switched. The earlier shrouds are sized for the smaller diameter two piece 4-blade metal fan or aftermarket fans the same diameter. The later shrouds are sized to fit the 7-blade plastic fan or the 4-blade plastic fan conversion.

Basically there are two early bolt patterns and one late pattern. Figures are approximate center to center distances of the holes in the shroud. Later shrouds (68-70) have slotted holes so the horizontal distance varies a skosh. Many people have modified the more economical Early "B" type 65-67 1/2 1600 shroud to work on 65-67 1/2 cars that originally had the Early "A" type shroud. We used to use the cheaper one in all kinds of applications to save a buck, whether it was slotting holes or adapting an extra bracket, it always was a great savings over one of the more expensive versions. It will only work on 1600's using the original 2 pc metal fan; or one having the same diameter. The later plastic fan cars can not use this shroud.

However it ends up being mounted, you have to ensure that the shroud ends up positioned on the radiator so that the fan has clearance all the way around, by making new holes, or slotting the existing ones.

"Depth" refers to how tall the shroud is when you lay it on its "back" on a table and measure the the "height".

"Vertical" and "Horizontal" refers to the center to center distance of the mounting holes.
