1937-1948 Flathead Water Pump Kit, Driver & Passenger Side

63" & an overall pump height of 9". We got your back with our Speedway Flathead Water Pump Kit! 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 5/8 shaft, making the assembly exceptionally strong and more efficient. All mounting areas are spot faced for improved fit and sealing. Severe-duty roller and ball bearings. Ceramic seals on sturdy 3/4 shaft.

High-flow modular impeller reduces cavitation. For systems with 5/8 drive belts. By Ike on January 20, 2022. I bought this pair this week. They look and feel great...

But when i installed the driver side i had to grind away casting material around the upper left bolt hole to allow the pump to seat against the block. The passenger side was much thinner in this area and seated fine.

Yes, I recommend this product. By Dirtdigger on September 12, 2021. By Sonny on June 25, 2021.

Installed them on my 40 Ford PU and the added two fins an larger bearing should be long lasting pumps. It definitely ran alot cooler. Excellent service means I'll be back!

By Kym the suffering wife on March 05, 2021. Living in country Australia makes it difficult to find parts for the engine my husband is rebuilding. Until he found Speedway motors that is.

He's ordered several parts from here now and has decided to make them his GOTO supplier. By Jackie on February 15, 2020. Related Items / Suggested Parts.
