Should I expect my engine to overheat? As it is, my thermostat has never gotten above 35-40% of it's travel. I guess since I drive for efficiency, it really wouldn't get that hot. I blocked off about 30% of my grill this morning and took it for a 15 mile spin - no change in the thermostat that I could visually detect.
I am thinking about completely blocking it off, but that means no direct air flow to the radiator what so ever.
My initial thoughts are that if I do this my engine temperature will rise slightly of course. But, that's my aim. I want the engine to warm up faster and stay a little hotter for more fuel efficiency. Plus there should be a bit of an aero advantage. I think that it won't overheat assuming I don't go race it. I think that manufacturers include grills because of liability. They don't know what the end driver will be like, or what he/she will use it for. So, they want to prepare for the worse. But for ME, who never has the engine above 3k rpm, I suspect it won't be an issue. I want to prepare for the winter by doing all that is possible to reduce fuel efficiency decrease.
But I thought I would get other peoples opinions on this as well.
