There are many items to consider in a Porsche LS3 swap, and the next item to consider is the cooling system. With the fuel system sorted out utilizing a nice set of Holley fuel rails and custom lines, we could begin adapting the Porsche LS3 cooling system. Although the routing of the Porsche LS3 cooling system can seem a bit “complex” it is fairly simple and utilizes most of the stock hard pipes.
We opted for the Renegade Hybrids electric coolant pump and front adapter plate to optimize space constraints. The rear-most hard pipes were replaced with flexible hose supplied with the kit to adapt to the stock remaining Porsche system.
