I f it has the stock clutch fan than all its doing is spinning the fan and the clutch will keep it from spinning the motor.
You want to put a wrench on the main pulley, the bottom one, I believe it is 19mm or a 17mm cant remember.
That will spin the motor, but remember pull the plugs first otherwise you can jump on the wrench and the motor wont budge. On mine with the plugs pulled I can easily turn it with one arm.
