To make your Corvette driving experience the best, many people are choosing to outfit their early Corvettes with the new LS series engines. Technologically advanced fuel systems, reliability, higher horsepower output, and drivability make this a simple choice for many enthusiasts. The next question is.. How do you keep these motor cool and how much fabrication will be involved to make the conversion? Thankfully the "Direct Fit" line of aluminum radiators has solved much of the problems. Just imagine a high-performance aluminum radiator specifically configured for the LS engine that will drop in to your Corvette's factory radiator support. Problem solved!
The Direct Fit LS conversion radiators feature both the inlet and outlet ports on the passenger side. A steam line connection, 16" SPAL electric fan (because we are going to keep this monster cool!), radiator end tank temperature switch, billet radiator cap, relay and wiring harness is included. This Direct Fit LS Conversion radiator is designed for 1955-1960 Corvettes. Features an original width core and factory style side bracket mounting into the radiator support. Note: This radiator features an internal transmission cooler for Corvettes with an automatic transmission. 4-plate aluminum cooler with 3/8" NPT port threads and Jiffy-Tite quick connect fitting.
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 over replacement 4-row copper radiator. 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, and trouble free service for many years to come. Direct Fit radiators include factory style tanks for a radiator that not only drops-in place but also looks OEM.
Direct Fit radiators are available in your choice of natural, black ice coated or polished aluminum. Black Ice is an OE-style epoxy finish designed to turn an aluminum radiator into a factory look-alike without affecting cooling performance. Specify radiator finish when ordering. Additional costs will be incurred for black ice or polished aluminum. Polished aluminum radiators require an additional 2-3 weeks for delivery.
Dewitts Direct Fit 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 from 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!
