I think you get to a point in old car ownership where the car's pretty close to the way you want it, and you just tinker with little stuff (If it ain't broke, give me a minute!). Anyway, my '65 Skylark has always heated up a little at idle. I'm running a Champion radiator and a 180* thermostat, and it'll run around 185-190* on the road. When I stop at a light, it'll creep up to 210* if I give it enough time. It's nothing dangerous or really even a problem, but I noticed that my fan blades are mostly inside of the shroud. I included a picture that's about even with the edge of the shroud, just enough of an angle to show you the edge of the fan. Anything I can do about this? It might not even be the right shroud...It's been on the car for the 17 years I've owned it.
