Re: Engine Fan clutch operation Q.

[img]images/graemlins/tongue.gif[/img] There ARE different clutches for different jobs. We bought one for our FS GM 3/4T 350/SM465/Np205/14-Bolt FF and the thing NEVER really shut off, so we took it back and got something a little less aggressive. Those Chev-Lay pickups usually have "fan" on startup, and then it fades away and you don't hear from it again until you are pulling that grade outa Salt Lake in third-under with a gross weight of about 20,000 Lbs.....(yes, we DID split the transfer case for eight speeds forward in two-wheel drive).... THEN you'll hear it as it takes a good-sized bite out of your horsepower cookie. [img]images/graemlins/crazy.gif[/img]
