Description

Cold Case Night Rider Black Series radiators blend performance with original appearance to give you the best of both worlds. You will be hard pressed to find a difference between an original versus a Cold Case radiator. All Cold Case radiators are 100 percent TIG-welded aluminum to withstand high temperatures and the extreme pressure a performance engine can put on them and feature OEM appearing stamped tanks. Select the Cold Case radiator for your make/model/year vehicle for that perfect restored appearance of stock without sacrificing performance.

Key features of Cold Case Night Rider Black Series radiators:

* 100 percent TIG-welded
* All Aluminum construction with stylish black powdercoat finish
* OE style tanks
* Corrugated fins give more surface area and more thermal transfer
* Pressure tested
* Available for automatic and manual transmissions
* Works with the factory fan shroud (unless noted otherwise)
