Cummins ISC radiator fan

My friend has a 2001 Numar Mountain Air Motor home built on a Spartan chassis. Powered by a 8.3L Cummins ISC, 350 HP Diesel engine. His Radiator Fan is operated by a continuously running hydraulic motor powered by the Power Steering pump.
He says that he saw an advertisement for a kit or retro fit unit that operates the fan thermostatically only when needed, now that he is planning on doing some work on the MH he cant find the information. Is anybody here on irv2 familiar with this?

Hi richardcoxid,
I just asked this question of Cummins and the shop that does my chassis work.. Both said there is no after market kit for the Cummins ISC fan. Go to Welcome to Horton Worldwide and see if they have a kit. Horton is one of the biggest players in this aftermarket.
