Walker’s 4 core radiator for the 1917-23 T’s measures 22 ½” tall and 18 7/8” wide. To the outside of the mounting flange on each side is 22 5/16”. Bottom tank is 1 5/8” tall and upper tank is 4” tall. Lower hose outlet for 1 ¾” hose, upper hose outlet 1 ½”, transmission cooler hookup is 1/8” -27 NPT, and the radiator fills on the back side. Dummy neck on top is 2 ¼” tall. Fits most OEM style T shells including Speedway’s fiberglass shell.

You mention dummy filler neck. Hard to tell in the picture. Am wanting to mount this radiator inside the T-Bucket deep grill shell, but don't want to drill the hole in the top of the shell. Is this the radiator that would work? Using on a 383 Stroker.

Speedway part number 820Z4811. They do have a dummy filler neck in them, the picture on our website is a general picture of a walker raidiator. All of the T radiators we sell either have a dummy neck like this one, or a functional centered filler neck.

Red Line 80204 Water Wetter Coolant Additive
(Part #91015709)
                        

Red Line Water Wetter Super Coolant additive is a unique wetting agent which reduces coolant temperatures by as much as 20° F. This is a liquid coolant treatment product which is designed to be added to solutions of antifreeze and water to help improve the heat transfer properties of glycol-based antifreeze. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Improves the ability of coolant to wet heat transfer surfaces by 50%.

  • Reduces or eliminates bubbles that form on hot metal surfaces to reduce coolant temperatures by up to 20°
  • Superior heat transfer properties compared to glycol-based antifreeze
  • Compatible with new or used antifreeze (including DEX-COOL and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems
  • Improves heat transfer and reduces cylinder head temperature
  • Designed for use with all modern aluminum, cast iron, copper, brass and bronze cooling systems
  • Cleans and lubricates water pump seals
  • Reduces cavitation and complexes with hard water to reduce scaling
  • Does not lower cooling system below the thermostatically-controlled temperature
  • 12 fl. oz. bottle treats 12-20 quarts

1917-1923 T-Bucket Aluminum Radiator
(Part #91015600)
                        

These 1917-1923 T-Bucket radiators are built to work without a grille shell and look good doing it! Speedway T-bucket radiators do not use a conventional "pressure" radiator cap, rather they use the decorative "T" caps to seal the neck at the top of the radiator. A hidden pop-off valve (sold separately) is used for pressure control. Gasket # 91112222 is very helpful for sealing the decorative "T" caps.

Features Chevy position outlets, auto transmission cooler, and approx. 1 gallon capacity. These accept "T" radiator caps and accessories, but are not included.
