Tim’s Garage Episode 10: Saturn Sky Redline /Solstice GXP Howe Radiator Upgrade

In this episode, I obtain and install a WERKSracing Howe Radiator from Performance Autowerks to upgrade the cooling capability in preparation for a little additional horsepower. I detail the modifications needed to install the factory fan assembly and also the minor modifications needed to use the DDMWorks front rail cross-brace. The radiator is a very tight fit and is exceptionally well engineered to accept the factory A/C condenser, factory power steering cooler and the factory LNF airbox assembly. The version I used is for an automatic transmission equipped car. The capacity of the internal transmission cooler looks to be of higher capacity than the factory GM unit within the stock 5/8” thick aluminum and plastic radiator assembly.
