1933 Chevy Master Radiator

An original 1933 Chevy Master Street Rod Radiator used a 2-1/8" Harrison V Cell film core with a water passage of 1-5/8" with 1/4" lead dip on the face and rear and we frequently replace this with a 1-13/16 10FPI tube and fin core. 

When we grow this core, we need to make accomodations for the stabilizing framework on the bumper side and the horizontal support bar above the fan on the engine side that is flush with the core.

The original Harrison cellular core was comprised of narrow passages that can clog with rust, sediment or get coated over time with hard scale or oil from the engine.  

Images reflect past builds and illustrate various elements of design.  The radiator you order will be constructed based on the information you provide for your bespoke build.

Made in the USA

Here's a good tip from a customer:

The replacement fan for original Chevy 6 cylinder passenger cars is marketed for everything from 1931-1954. The original 15-3/4" fan is one of the few parts on the Chevy Standard that is shared with other Chevy models and years.

1937-38 passenger car water pumps puts the original fan too close to the radiator. Part # 838933 is readily available and also measures 15-3/4".  It can be adapted to earlier pump pulleys by enlarging the holes slightly. The fan sits 1/2 inch lower on the pulley than the original fan providing additional radiator clearance.
