i'm wondering if the more open grill will make my ambient temperature issues even worse. With the Overland, driving with the plow on over about 25 mph or so, the plow causes a very low pressure area ahead of the grill.It’ll probably fit better. I see reports that winch wiring fits better on the new grille.
Hot engine bay air is drawn FORWARD, heating the ambient temperature sensor and actually causing the engine temp to get into the 220s even when it's 0 degrees outside.
When the ambient outside temp reads 70 to 101 like it often does with the plow mounted driving on the highway, the HVAC shuts off all heat to the cabin - believing you need COOL air and it gets bloody cold inside that thing.
I have found I need to trigger JSCAN to run the engine fan on high speed to offset that low pressure area caused by the plow and actually pull air IN, back into the engine bay and across the radiator.
I'm sort of wondering if the larger grill area will cause more air to leave the engine bay..........
Wiring should be better - large cables go up between grill and bumper to the snow plow to operate the hydraulic motor, lighting and so on. I tuck the connectors back in behind the bumper to keep them out of the weather otherwise.
