How We Choose
During an engine swap, things can pop up that you might not have seen coming, like needing radiators with a drain petcock on the passenger side, a fan shroud for the water pump-driven fan, or the upper hose on the passenger side. While hoses can fix most of that getting the correct width radiator for your core support if you need truck spacing or a budget-minded electric fan for the innovative builder. We picked some of the most popular LS engine swap radiators but we chose not to include electric fans in the list as a deciding factor, you can purchase a fan kit with relays and all the stuff needed to wire up the electric fan setup in the box that best fits your radiator fan needs.

The bottom line is when you are building a custom car or truck you don't want to figure out the size that you need after you have already bought the kind of radiator that you thought would work.
