It's still running about 230*. Doesn't seem to boil, but. Made sure the coolant was topped up. Didn't matter.

Have you verified the temp gauge is correct? Sometimes they are a bit off and if it is not boiling perhaps it is not as hot as you think. It is not easy to add a second thermometer to get an identical reference but I wouldn't trust an infrared type for measuring actual water temp in this situation either.

Better I think would be to stick some kind of probe type thermometer in the upper tank as close as possible to the hose opening to measure water returning directly from the engine flowing out of the upper hose. At that location I would think you could get a fairly decent reading. Amazon has several inexpensive type thermometers with the folding probes and a few other oven types with probes on flexible wires.

If it turns out the gauge is correct then maybe check timing and for vacuum leaks along with a good flush and even checking the water distribution tube would be in order.



No, and quite frankly, I have done nothing but identify the issue and top off the coolant. I have yet to take an infrared to it to see what that reads - because it's easy. I wonder if the gauge has pooped out. Maybe.


I do know that the previous owner, the one who rebuilt the engine, installed a 195* t-stat into it and a new aftermarket temp gauge. The stat does need to go since that engine was designed and tuned to run right below the boiling point of ethanol. It's quite possible that changing the t-stat will solve its tiny ailments.


No matter, it can sit until Thanksgiving and I'll haul it back to the Land of Fred and spend some time this winter sorting it out. I think that it may have a coolant leak somewhere, too. And a new (better) gauge may be in the works.


Thanks, as always, for the tips and directions. At the end of the day, this is truly a First World Problem.
