    Good Aftermarket Fan to replace blown Aux Fan

    Well, my Aux fan went, so I need to place it. I know it will need some modifications to fit in the aux fan casing, but whats a good aftermarket fan to replace it with? Brand? Dimensions? Pull/Push? Will any custom wiring be needed? Etc,

    Thanks in advanced!

    Have you considered the following:

    1) pull out the aux fan completely.

    2) remove the engine fan.

    3) install a spal or other brand puller fan to the back of the radiator.

    4) wire up the spal to come on via the aux fan switch/ac compressor.

    This would be a lot easier than modifying the aux fan casing to accept an aftermarket fan.
