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.

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.
The upper neck is left of center about 6".
Has a 3.875" upper tank thickness with a 3" core thickness.
Choose from buffed or polished

Red Line Water Wetter is a unique wetting agent which reduces coolant temperatures by as much as 20° F. This is a liquid 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
