I'm just going to mount my crankfire trigger wheel behind the fan, the problem is that the motor is already installed in the car and I have an extra fan sitting on my workbench with no markings for TDC which I need to know in order to make sure the trigger wheel is mounted properly.
Is there a sure fire method to know where TDC is on the fan without the fan being installed?
I'm pretty sure there are no markings at all on my fan, if there are some, I don't see them
