    I've changed about 4 viscous clutches in the last month....

    When they seize they take the belt and wiring with them.

    I thought when they seize up they just turn with the engine. No.

    Depends. There's a slip ring on there that houses the electric coil to engage the clutch. If that seizes it tears all the wiring to the clutch apart. Those clutches are like $700

    Not yet,checked the relay which is working. Pulled the relay out and installed a jumper wire so we bypassed the computer and got air coming out of the selonoid.We figured out there's a bad wire somewhere between the relay and computer,and also the clutch fan needs to be replaced or rebuilt. Looking for a wiring diagram.
