Overall Assessment

Customers commend the product for its great build quality, excellent fit, and reasonable price. They state it is compact, practical, and provides additional space for installations. Its adaptability is particularly noted, with one user employing it as a successful replacement for a Walker in aluminum. Users find it effective in various specific applications, such as being recessed into the backside of the original honeycomb radiator, resulting in higher efficiency. Some criticisms include the lack of a drain plug and a radiator fill neck; however, they do not outweigh the product's strengths.

Perfect fit for '37 Ford car

Looked and looked for a direct replacement of the Walker in aluminum - No joy anywhere. Took a chance on this one and couldn't be happier. Welded a flat bar across the bottom to span the frame rails. At the top, made and welded on an "elephant ear" on each side to tie the top tank to the upper grille shell. Made a simple filler neck out of aluminum tube and a few pie cuts to turn it 90 degrees. Used Speedway Weld-On Billet Aluminum Radiator Filler Neck and done ! Flanges on the sides of the core worked perfect to mount the existing AC condenser and electric fan.

Fair for the price...

Fair radiator for the price. Lack of radiator fill neck complicates bleeding air out of the system... especially since there is no additional 1/4 or 1/2 or 5/8 nipple on top tank - in addition to the 1 1/2 hose neck. Really needs to be added or find a tank with one. Will eliminate air issues
