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.
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!

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 antifreezeCompatible with new or used antifreeze (including DEX-COOL and long-life versions) to improve the heat transfer of ethylene and propylene glycol systemsImproves heat transfer and reduces cylinder head temperatureDesigned for use with all modern aluminum, cast iron, copper, brass and bronze cooling systemsCleans and lubricates water pump sealsReduces cavitation and complexes with hard water to reduce scalingDoes not lower cooling system below the thermostatically-controlled temperature12 fl. oz. bottle treats 12-20 quartsWater Wetter Tech Info (PDF)Learn more about how cooling systems work with proper coolant mixture and additives by reading our tech article.

Note: The cap for the dummy neck could be number 91122002 or one of the other Model A caps. The pressurized cap at the rear of the upper tank could be as low as a 15lb cap and up to a 32lb cap. Engine you run dictates which cap would be needed. A commonly used cap is our speedway cap number 91015620.
