If you don't want to get fancy with an AEV Hood (like mine
) or poison spyder louvers (like many others), then you can just use some generic louvers and cut some holes in your hood.
I flushed the coolant system, ensured the radiator was not full of mud, replaced the thermostat to a hi-flow unit (same opening temp as factory) and have the factory fan that's always on (no thermo viscous clutch), and I run at about 88-90C all the time which is actually a little low.
