TA Performance offers these high quality, all aluminum, Direct Fit, Fullsize radiators that exceed the efficiency of original radiators, and they look great too!. They feature a vacuum brazed aluminum core with hand formed tanks that are beautifully heli-arc welded for exceptional cooling and reliability. The smooth tanks and top of these radiators give that custom, show car look. These radiators were developed in Phoenix, AZ where air temperatures can exceed 120 degrees and surface temperatures can be 160 degrees or more. We use two large cores as opposed to three or more smaller cores which results in better heat dissipation especially in low air flow situations. As the air passes through the radiator it takes with it heat from each core, on conventional radiators that use several cores the air is heat saturated by the time it reaches the last one or two cores, allowing the hot coolant to continue to circulate, thus raising the base temperature of the cooling system. TA Performance aluminum radiators that use two larger cores allows for a greater amount of heat to be introduced into the air stream without the saturation effect. These radiators are made to be installed directly into your Buick with no additional modification or fabrication. Beware of other aluminum radiators that are considerably less expensive, they are usually small universal type radiators that require additional work to install and are usually inadequate to cool higher horsepower properly. Available with or with out a built in transmission cooler, please specify. Please confirm your radiator size before ordering.
