The plastic/rubber shield below the radiator is solid & in place....actually have it in front of the sway bar to channel air a little better......I've wondered about the radiator cap - knowing the #'s verus degree factors involved but was worried an increase might be too much - currently the stock 9 bar cap is in place (new).....these pulls are not @ 35MPH/50KPH always mostly below......the cooler for the trans has a fan and is in the upper left hand quadrant of the radiator...I've though about relocating but it puts it close to road debris harm....there is no belly pan.....H2O seems to leave it suseptible to hot soak/heat build up on long hauls & does not recover as quickly as when the coolant is present/// A/C is also not as efficient and gauge runs a little hotter.....the LED's in front of the grill are 4x4 each - much smaller than the previous LED light bar or Daylighters.....looks wise almost too small but work well enough....I'd attach pic's if I could.....think higher value pressure cap ok?
