Where you are (CA) I would add one, it will only serve to save your pump and your steering unit and has "0" downsides IMO.
Doesn't need to be anything extravagant, even a pipe that goes away from the engine heat then back again is more than enough. My Santa Fe has one that goes up against the lower cross bar in the front engine area, no fins, just a pipe that touches the bar to dissipate the heat.
