I recently changed out my factory fan for an aftermarket. At the time, I wanted to substitute a push fan for the stock pull, as the space between the radiator and the engine is very tight. Considering the rule, I thought it could be considered illegal, as the fan would move to the front of the radiator instead of behind the radiator, which I considered a "relocation". I was able to find a thin pull fan, so it all worked out.

I still wonder, would moving from a push to a pull, and the subsequent required relocation of the fan (from the back to the front of the radiator) be considered legal?

Thanks,

Will
