TESTING

1. Disconnect the negative battery cable.
2. Check to be sure the radiator fan rotates when spun by hand.
3. For 1990–94 vehicles proceed as follows:
   1. Connect 1 end of a jumper wire to terminal 4 of the coolant fan motor connector. Connect the other end of the jumper wire to the negative battery terminal.
   2. Connect 1 end of another jumper wire to terminal 2 of the coolant fan motor connector. Momentarily connect the other end of the jumper wire to the positive battery terminal.
