Do you want cooling improvement and performance? During a test, a Be Cool aluminum radiator was installed in a 1955 Chevy in about an hour and lowered its operating temperature from 220 degrees to 180 degrees F--even with the air conditioning going full-blast. Be Cool custom-fit aluminum radiators are designed to be a direct fit, and they feature 15 percent more cooling capacity than factory 4-core models. What's more, they can be used with all brands of antifreeze and are available in both standard and polished finishes.
