The 429 CJ/SCJ came with an Extra Cooling Package which included a three row, higher fin density radiator at 13 fpi (fins per inch) instead of the standard duty radiator at 10 fpi. Cooling system components are shown and described below:

The D1ZE-EA is the radiator used with the 429 CJ/SCJ and C6 automatic. Note the transmission oil cooler fittings on the left side tank for the internal cooler. Interesting Note: All Ford replacement radiators had the trans oil cooler, so if you went to dealer to order one for a 4-speed car, you got the cooler anyway.

The D1ZE-DA is the 429 CJ/SCJ 4-speed radiator. Note the absence of the Transmission oil cooler fittings.

Fins Per Inch

The picture at left is the 10 fin per inch D1A 429 CJ Torino radiator. The picture at right is the 429 Mustang/Cougar 13 fins per inch unit. The additional fins/inch allow more surface for heat transfer and improved cooling performance.

Fan

The 429 CJ/SCJ used a 19" seven blade fan stamped with part # D0OE-A is visible on the front surface of one blade as shown.

Factory Fan Shroud

The factory fan shroud was made out of fiber glass and has Part# D0OE-8146-D molded into the left top corner. Additionally, the supplier name is also molded in - Barnum Bros. Fibre Co. Inc. The diagram below shows the installation of the fan shroud.

Crites Restoration makes the shroud shown above which is made from fiberglass like the original.

   

Dearborn Classics makes this shroud from Polypropylene. Some members who have this shroud had noted warpage due to underhood temperatures.

Water Pump

An NOS 429 CJ/SCJ water pump is shown above. Note D0OE cast in part number and the underside view showing the impeller. The rear water pump backing plate is shown below;

Thermostat Housing

The part number (C8SE 8594-B) is stamped on the flange as shown. Either a  PVS (Ported Vacuum Switch) or an EPVS  (Electric Ported Vacuum Switch) threaded into to the top of the housing to provide vacuum control to the distributor.

Fan Spacer

This is the fan spacer used for the 429 CJ/SCJ. It has a C8SE-B part number on the fan pilot hub as shown. The C8SE spacer has an overall length of 2 1/8".

This is a side by side comparison of the C8SE-B spacer (right) and the more common longer C8AE-F spacer (left) found at swap meets. Also note that the correct C8SE-B spacer on the right has a much larger pilot hole to fit over the D0OE water pump shaft.

This Autolite radiator cap was removed from a very original, low mile 71 429 SCJ Mach 1. While it is possible it could have been changed early in life, it is an original Autolite cap and seems reasonable that it was original. Anyone else who believes they may have an original cap, please e-mail the webmaster with photos so we can see if it is this same design.

Radiator Air Deflector 

This is the radiator air deflector that clipped (using the 4 clips shown above) to the top front edge of the radiator. It filled the gap between the radiator and the rad support to help direct air entering the grill through the radiator instead of by-passing it by flowing over the top.

 Below left and center are two views showing this air deflector installed on a 351. Photo below right was taken of a 71 429 Mustang in the mid-70's showing an air deflector was present.

Overflow Bottle

Although 429 Mustangs and Cougars were not equipped with Overflow Bottles from the factory, Ford did sell generic kits over the counter like the one above that could be used.
