  • Speedway Electric Cooling Fan
    From: $29.99
    New
    Speedway Electric Cooling Fan
    (Part #910158)
    x
                

    Help your engine keep cool by adding an electric cooling fan to your radiator. Electric fans are far more efficient than mechanical engine driven fans because they free up horsepower and only run when you want them to (when used with a fan controller, not included). Plus, most electric fans can be mounted ahead of the radiator or behind the radiator, with the more efficient location being on the engine side of the radiator.

    • Choose your size diameter (10", 12", 14", 16")
    • CFM Ratings per size:
      • 10" - 800 CFM
      • 12" - 1000 to 1100 CFM
      • 14" - 1200 to 1300 CFM
      • 16" - 1750 to 1850 CFM

    Note: These fan CFM ratings are based on 13 volt input (normal for auto voltage) and on variance in motors used.  Some fans may run better than others depending on your specific application.

  • 1949-53 Flathead Car Water Pump with Double Narrow Belts
    1949-53 Flathead Car Water Pump with Double Narrow Belts
    (Part #91015595)
    x
                

    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.

    Speedway's 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.

    • Ceramic seals on sturdy 3/4" shaft
    • High-flow modular impeller reduces cavitation
    • Gasket included
    • Passenger side pump includes threaded boss for heater hose connection
    • Driver side pump does not have heater hose connection

    Fits 1949-1953 Ford cars and 1952-1953 Mercurys with 3/8" belt system. Also fits 1953 F-100 Pickups.
