4×4 modifications

Even though we all dream of blasting through the desert at 130-MPH like Robby Gordon, most of our 4×4 adventures take place at a much more reasonable pace. Unfortunately for our engines crawling along a boulder strewn dry river bed or climbing a goat trail through a mountain pass does not always allow enough airflow to keep our engines cool with a belt driven mechanical fan. Belt driven fans are designed to keep your engine cool when traveling down a street or highway not while crushing boulders at 3-MPH and 1,500-RPM. So what can we do to keep our rigs from boiling over this summer? Follow along with us as we install a pair of 11-inch electronic cooling fans along with a programmable fan controller both from SPAL USA.
