i did recently replace the vent cover on my hood to a raised scoop type! and it seems like anything could fall in there and burn up. shouldnt these come with some sort of filter protecting from things falling into the vent from outside? also, it smelled like something burning and it hasnt happened since. i have all fan speeds, i have heat and it blows strong. as far as the power steering thing, i havent seen any puddles underneath and no puddles on the inside from the heater core. so kind of a mystery right now. i had my thermostat replaced about 3 weeks ago and went from a 180 to a 195. the thing was sticking, not heating up plus the housing was leaking. so that should be good also!
