The Admin said some things aren't working yet on this updated version.

If you've tried replacing the thermostat, relacing or flushing the radiator, and still not resolved, most (including myself) found the fan clutch was the solution. I recall VXorado bought an aftermarket one that didn't work out or died soon, so then got an OEM and it solved his problem. I also recall some strongly recommend against flushing radiator as it will flush out things that may be plugging a small hole, and the radiator may start leaking.

You can test your fan clutch by spinning it and seeing if there's resistance, but I can't recall which way it's supposed to be.

We never did figure out what benefit the redesigned fan blade served.

Some have tried adding electric fans, but most have found that didn't work either, even though it seems it should. I recall there's one owner that has had great success with his electric fan, but I think he's the only one, and several others removed them.

One other point, one or two owners found the fan blade was installed backwards...so at least check that.
