A lot of good thoughts in the posts down below.

I've told many times about listening from the house while someone was out cultivating on our BN back in the day -- you rarely heard the exhaust, all you could hear was the fan. It moves a lot of air. And the result is, as others point out, that you could shut it down after a good workout, and the top of the radiator would be hotter than you'd want to rest your hand on, and the bottom quite cool.

The thermosiphon was very efficient with the high volume fan. It does need to be clean, though, as gene points out. Sounds like someone else did your motor, but both the 113/123 motors I've torn down, there was a lot of caked up sediment, mostly toward the rear of both the head and the water jacket. In one of them it was quite remarkable -- the muck in the water jacket was highest at the back and probably surrounded a third of the #4 sleeve and a quarter of #3. Who knows how thorough a job they did rebuiding your motor. What you might want to try before you refill with an antifreeze mixture is to scrub it out. You could start by opening it up as gene suggests and poking/scraping/blowing out what you can. Then follow that up by refilling with a solution of washing soda and water (two pounds to the 4 gallons or so it will hold) and give it a couple of good hot runs. You can get it to run hotter, as another of the guys suggested, by covering your grille or radiator. Cardboard works, but I usually just start the tractor and let the fan suction hold a tall kitchen trash bag up against the grille. A couple runs like that, especially after scraping and whatnot, will get a lot of the crud loose. Drain and flush with a hose, refill, give her another hot run with plain water, then drain and refill with your antifreeeze mix.

It seems like a lot of trouble, as it sounds to me like your system is working just the way it's supposed to but it might set you more at ease knowing your system's clean.

As far as a gauge, look at the lower, inlet casting on the front of your motor. It may already have a plug in a hole tapped out to take the temp probe. If not, it will have a heavier section that you can tap into for that purpose. In that setup, the gauge mounts over on the right side using a couple (maybe just one) of the bolts securing the governor housing to the crankcase.
