The 2 fans in the first scene are in the primary cooling circuit which is used by the transmission heat exchanger, the engine and its lubricating oil heat exchanger and the hydraulic system heat exchanger. The fans are hydraulically operated and we wanted to make sure they would run and not leak or make unusual noises. All of the hoses on all fans have been replaced. The single fan seen last is for cooling the radiators in the turbochargers aftercoolers. There are 36 radiator sections in the cooling hood, 8 of which are for the turbocharger aftercoolers. The original radiator sections were stolen by copper thieves years ago and the units seen in the video are newly manufactured. They will all be replaced.
