    Did all the Detroit 60 engines come with clutch fans I'm looking at a 99 Sterling triaxle that doesn't have a clutch fan unless someone changed it out. Thanks

    Fan clutch is truck manufacturer installed. Not an engine component. So as you already noticed, it depends on the truck, not the engine. If it has a fixed fan, shouldn't be that big of deal to put a clutch in if that is what you want.

    Sure it isn't a viscous fan clutch?

    Ok thanks just thought they came with clutch fans. Think it's a mechanical fan though .Truck runs cool so i guess it doesn't matter.

    Engine fans use horsepower. Horsepower used = fuel used. You don't need it running all of the time. As @spsauerland said it could be a viscous fan clutch. You should find out.

    35-45 HP the fan will use in most application's. Noise , and low mpg will be the results of fixed fan.

    Sorry if I keep asking stupid questions this is all new to me. A viscous fan clutch uses fluid alone and NOT air right? So I can just install an viscous fan clutch instead of trying to trouble shoot why my clutch fan is running all the time.I can buy a used viscous fan clutch for 200.00.:confused:

    In the automotive world they are stand alone items (no external connections). I deal with a lot of bigger Horton viscous clutches and they are triggered electronically. You're better off with air IMO.
