I bought an '84 Westy with a GEX rebuild the other day. It's been running
pretty good around town, but when I took it out for a longer cruise I got
the dreaded blinking coolant light.

The temp gauge was just above the LED while on the highway at about 60mph,
then I turned off and headed gradually uphill at 35mph when the LED
eventually started flashing. I stopped awhile to let things 'cool' a bit
(ambient temp was 105) then carried on to my destination.

The fan seems to come on only when I'm running the A/C (I wasn't at the
time). Did the aftermarket unit override the main fan sensor?

What can I do to keep the thing running cool in HOT weather? I've got
another three months of 100+ temps so need to figure something out.
