Description

Cold-Case performance aluminum radiators are available and affordable for all. These high-quality, tube-and-fin performance radiators are true OE styles for most applications. Each Cold-Case design distributes fluid more evenly, eliminating hot and cold spots. Also, the massive cores take up the entire width of their tanks, so you get the most efficient cooling possible. The radiators drop-in without modifications needed (on most) and look original. Plus, Cold-Case stands behind its quality and research with a limited lifetime warranty on their products.

All Cold-Case radiators feature:

* Lightweight, efficient aluminum construction
* 100 percent TIG-welded
* Internally welded filler necks offer a clean, factory look
* Two oversized cooling rows for increased capacity
* 1 in. to 1 1/4 in. tubes for higher volume
* Works with factory filler cap
* Includes OEM-style petcock
* 42.7 percent lighter than comparable copper radiators
* 30 percent thicker materials than no-name aluminum radiators
* 60-day COOL guarantee
