Replacing my cooling fan - mounted in front of the radiator -- it is held in place with nylon ties. As far as I can tell, these move only one way through the radiator (once they go in, they do not come back out again). Can anyone tell me - best way to remove them is to snap off the heads and pull them through from the inside? Never done this before and would be nice to accomplish without screwing up.
Thanks.
