Upgrade your shark bodied 327 or 350 Corvette cooling system with a 66-late 427 style radiator. This new 24" radiator and fan package is designed to substantially increase cooling capacity while mounting into the original small block core support. Our conversion radiator features pins for the lower mounts just as your Corvette was originally designed. (Factory 327/350 w/o AC 4-spd Corvettes featured an 18" aluminum radiator) Radiator mounts on the top with side brackets that attach to existing holes in your Corvette's radiator support.
Direct Fit radiators are completely manufactured and assembled right here in the United States. Along with that comes the quality that you would expect from a company that takes pride in turning out Corvette radiators. Each Direct Fit Corvette radiator begins life as an aluminum core with two 1" wide cooling tubes. This configuration more than doubles the cooling capacity by increasing the "tube to fin" contact area. This can only be achieved with an aluminum radiator since the aluminum material does not dramatically affect the radiators weight. Tanks are press formed and inlet/outlets are correctly configured for a drop-in installation. Each core is then brazed in a controlled atmosphere furnace; which eliminates the need for epoxy, ensuring leak free, trouble free service for many years to come.
Pre-installed dual electric SPAL fans eliminate the need for the stock fan shroud and engine driven fan. The kit also includes one SP195FRH and one SPFH relay harness.
Note: This is a custom package and modifications are required to complete installation. Cars with AC will require custom lines to the condenser. Custom radiator hoses will be required. Made in USA.
Dewitts aluminum radiators are warrantied to be free from defects in materials and workmanship for as long as you own the Corvette in which it was originally installed. This warranty is extended only to the first retail purchaser of any such radiator. Proof of purchase must be provided in the way of a sale receipt from DRI or an authorized dealer. If the radiator is used in any racing application this warranty is considered null and void.
Radiators used without an adequate proportion of premium quality antifreeze coolant and distilled water are not covered by this warranty. DRI radiators require a correct proportion of quality coolant, which contains aluminum corrosion inhibitors in the formula and distilled water. All Corvette cooling systems must include a radiator pressure cap with the proper pressure rating. Distilled water and premium antifreeze must be used with all Corvette aluminum radiators!
