The Stovebolt Site Forums The Shop Area Engine Shop Running hot, what's too hot?

It will diesel for a short bit after shut off after running hot. Not all the time, 50% of the time. Does it for about 1 second.

One question that was raised privately, and also above by red58: is fan centered on radiator? Yes, left-to-right. No, top-to-bottom. Top of fan is 2-1/2" below top-most fin on radiator. And bottom of fan is 1/2" or 1" below bottom-most fin on radiator. Looks like I could lower radiator to center it top-to-bottom. I'm not sure how I ended up with fan not centered. In any case, seems off-centered fan wouldn't be an issue at speed, but I see no temp drop at speed.

Will try timing suggestions tomorrow...
