Losing coolant

[David Brady]

I'm surprised that your bus cycles the fan even on the flats. I can

go mile after mile on flat highway, regardless of outside temps, with

the fan off and the engine running cool, and engine temperatures

steady and below 190 deg F. Maybe this accounts for some of

fuel economy differences between the 2-strokers and the S-60.

I don't normally run the fan on manual, but have on the last two
travel segments, most of the time. Why? Because I've been worried about
the coolant loss, and wanting to keep things as cool as possible.



On this trip, which started mid-August, the air conditioning was on the
vast majority of the time until just a couple of weeks ago. That meant
the fan was on. As we've hit cooler weather, the A/C was off a lot.



With fan override on (manual or A/C), out here in the east where
there's no real mountains the coolant runs between 181 and
184.



Witn fan override is off, no matter where I am, it cycles between 189
and 197. Only exception is pulling heavy hills in heat, when probably
the sky is the limit but I hold it at max 200 by gearing down/going
slower as needed.
