Q & A

What's in the Box

Walker Cobra Series radiators boast a relatively thin, but efficient, high-flow copper core which is ideal for use with mild Small Block engines with stock or low compression ratios. Each radiator is built for a direct fit with heavy gauge steel side brackets and standard mounting holes pre-stamped. Plus, all radiators feature a built-in oil cooler for use with automatic transmissions. They work with original, reproduction, steel or fiberglass grille shells.

  • Dummy filler neck in OEM location - accepts stock type caps & accessories
  • Copper core w/ 1-piece brass tanks
  • Vertical tubes every 1/4" and 17 fins per inch of height
  • Heavy duty 12 Ga. steel side brackets w/ pre-drilled holes
  • Use a 15-18 lb. radiator cap
  • Brass drain cock
  • Simple bolt-in install w/ no modifications to grille or grille shell

Small Block Ford engines can take advantage of the less expensive and more readily available "Chevy" radiators by using a passenger side inlet water pump (such as our 910-15544) and get additional steering box/fuel pump clearance to boot!

1930-31 S SERIES 4-CORE RADIATOR
                        

Don't be fooled into believing you need a thicker core for increased cooling! A thicker core can restrict air flow through itself, decreasing it's own efficiency!

Cobra Walker radiators boast a relatively thin but very effective core with a vertical tube every 1/4" and 17 fins per inch of height.

All Walker radiators are made from the finest materials available;

  • copper cores
  • one-piece deep draw brass tanks
  • heavy duty steel side brackets

They easily withstand working pressures of 18 psi, incorporate an oil cooler for automatic transmissions (Flathead radiators don't have oil cooler) and a brass drain cock for easy service.

Each radiator is built for a specific application with heavy gauge steel side brackets and standard mounting holes pre-stamped. They work with original, reproduction, steel or fiberglass grille shells.

  • Model T and A radiators have a dummy filler neck in the original stock location to accept stock type caps and accessories. Most radiators have the real filler neck on the rear of the upper tank on the passenger side. The upper outlet will be 1-1/2" and positioned in the center or towards the Driver's side (depending on application.)
  • Unless listed as Ford Motor, each radiator's lower outlet will be 1-3/4" and positioned on the (RH) passenger's side. Ford motor applications will have a B prefix in the part number and a 1-3/4" lower outlet on the (LH) driver's side.
  • Small Block Ford engines can take advantage of the less expensive and more readily available "Chevy" radiators by using a passenger side inlet water pump (such as 910-15544) and get additional steering box/fuel pump clearance to boot!
  • Flathead engine applications will have an FH designation and have two upper and two lower outlets.
  • The Cobra Series is fine for mild small block engines with stock or low compression ratios.
  • The Z-Series is a 4-core design for big blocks, 400 cubic inch S/B Chevys, blowers, high compression, flatheads, and other cooling problem cars.
