    Electric would not be feasible since it would be in water, since electric motors don't work when soaked in water, they mostly die. A pulley mounted fan would be a good choice, by the way what vehicle are we talking about here?

    Viscous is a better choice

    Viscous drive fan can break in high reving situations under water. Thats the only risk. Electric is a big NO though
    Keep a cool head and wear seatbelts!

    @Spectra
    If you ever have the chance to watch vehicles driving through deep muddy terrain, You can reduce your tyre pressure as low as 1,2 bar on 4x4 vehicles, There are several basic rules on fording water. Either disconnect the fan-belt to stop the fan turning, or jam the fan if it has a viscous.

    Hi friends,


    sherwan_88 and Janj thanks for the suggestion. spectra I politely disagree with your opinion becuase I had a landrover defender 80 with Visco fan, I never had problems of stucking up of the fan even in 1 meter deep wadding on rocky terrain. I'm a Pakistani but live in Catalunya province of Spain where stratum is similar with our Potohar region. However, our seasonal channels have rocky beds and sometimes soil & sand (silt?).


    I'm retrofitting an old Stery Pinzgauer 710K with VW 2.0 TDi diesel engine along with matching ZF 6 speed transmission. The engine manufacturer recommends both options i.e. Electric or Visco fan for radiator cooling. In that scenario I sought recommendations on this forum.


    Best Regards.
