That's good advice dwm71, that should work on most Hondas (ones w/ "normal" size radiators) because whether both fans automatically turn on with A/C or just one to cool the A/C condensers, it will draw air through the radiator and cool it down.
I'm not at all familiar with Legends other than driving a couple, but many Hondas use a thermoswitch to switch the fans on once that "switch" gets to a certain temperature. For all I know it's possible that on Legends, at least those years, went off of a different chip of some sort(maybe taking temp from the temp gauge sender or the ECU temp sensor), rather than running the signal directly from the thermoswitch to the fans :dunno:
