Is there a radiator in this configuration with a A/C condenser

Is there a radiator in this configuration with a A/C condenser


May 14, 2015
We apologize but Walker does not list a flathead version for the 32 with the condenser. You could opt for the Griffin version number 91734432, condenser 7253332, and a high flow fan and shroud number 10680417FANZ would handle the cooling needs.

1949-53 Flathead Car/Pickup Water Pump with Wide Belt
(Part #91015592)

Original flathead water pumps have always suffered from unreliable bronze bushings and carbon seals. They almost always leaked and even Ford manuals warned mechanics not to tighten fan belts too tight. The excess slack allowed belts to slip and lose contact with the generator and water pump pulleys, causing more cooling and power problems.

Speedways completely new water pumps feature severe-duty roller and ball bearings, close tolerances and modular impellers to provide maximum flow and reduce cavitation. They also have modern ceramic seals on a heavy duty 3/4" shaft, making the assembly exceptionally strong and more efficient.

Note: This water pump is for 1949-1953 engines in 1948-1952 pickups or 1932-1948 cars.

  • Flathead Water Pump Features (Link)
  • Designed for use with 5/8" belt drive system
  • Severe-duty roller and ball bearings
  • Ceramic seals on sturdy 3/4" shaft
  • High-flow modular impeller reduces cavitation
  • Includes gasket and a connection for the heater hose return

Walker WS40 Radiator Fan Shroud, Style A, 20 x 21 Inch
(Part #82040)

Maximize your radiators effectiveness with a tight-fitting fan shroud. Use of these shrouds has produced temperature drops of up to 30 degrees!

Walker shrouds are vacuum formed from a very dense polyethylene. This high-impact, heat resistant material has a lightly textured, semigloss black finish. The cooling fan hole is not cut out so the installer can tailor that to the exact fan location and diameter.

See Application tab for application information.

B&M 70265 Super Cooler Polished Aluminum Transmission Oil Cooler
(Part #20070265)

The last thing you need in the middle of a race or a road trip is to have a transmission or engine go south because your oil cooler can't keep up. B&M's SuperCooler oil coolers will keep your transmission or engine cool and running in your time of need. They're made of lightweight aluminum, with an efficient "stacked plate" design. Multiple cooling paths give them the cooling capacity of larger fan-and-tube coolers. And, because they have a low pressure-drop design, there is less oiling-system restriction.

100% brazed construction provides superior strength and minimum overall size. Stacked fin and plate design is 33% more efficient than the same size tube-and-fin cooler.

Measures 4-1/2" x 11" x 1-1/2" thick with female 1/2 NPT ports.  Cooler efficiency rating of 7,500 BTU.

Red Line 80204 Water Wetter Coolant Additive
(Part #91015709)

Red Line Water Wetter Super Coolant additive is a unique wetting agent which reduces coolant temperatures by as much as 20° F. This is a liquid coolant treatment product which is designed to be added to solutions of antifreeze and water to help improve the heat transfer properties of glycol-based antifreeze. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Improves the ability of coolant to wet heat transfer surfaces by 50%.

  • Reduces or eliminates bubbles that form on hot metal surfaces to reduce coolant temperatures by up to 20°
  • Superior heat transfer properties compared to glycol-based antifreeze
  • Compatible with new or used antifreeze (including DEX-COOL and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems
  • Improves heat transfer and reduces cylinder head temperature
  • Designed for use with all modern aluminum, cast iron, copper, brass and bronze cooling systems
  • Cleans and lubricates water pump seals
  • Reduces cavitation and complexes with hard water to reduce scaling
  • Does not lower cooling system below the thermostatically-controlled temperature
  • 12 fl. oz. bottle treats 12-20 quarts
