In part 27 of my '76 Mazda RX-5 Cosmo restoration, I focus on the cooling system. It seemed an appropriate thing to do with the hot summer weather. The stock Cosmo rad was leaking, small and hard to obtain so I installed a universal aluminum radiator after modifying it to fit. With the new rad, the oil cooler had to be relocated, the engine water inlets/outlets modified, and a number of other changes had to be made. Once all that was done, it was time to install the dual cooling fans. Now that the cooling system is new, modern and overbuilt, I should have no problems even under the worst conditions. Included in this episode: modifying a universal rad to fit, TIG welding brackets, making oil cooler brackets, MIG welding them in place, modifying thermostat and water pump housing, mounting the oil cooler, trimming and modifying an electric fan shroud to fit the rad, welding mounting fan mounting brackets, wiring up the e-fans, testing the fans.
