Subject:      '91 Westy Coolant/Fan
Content-Type: text/plain; format=flowed

It's weird science at Bob's house.
1/ After an entire weekend of driving up steep hills to heat the engine up
enough to get the fan to come on, no luck. The temp gauge stays at the LED
so the engine does not appear to be overheating. Coolant stable in both
tanks. No leaks or coolant loss.
While continuing to "mess" with the idle (it's high-1200-1400) and cleaning
the throttle valve switch and putting everything back together, for some
obtuse reason I turned on the air conditioning dial about halfway. The
engine cooling fan immediately went on! Whenever I turn on the air
conditioning, the engine cooling fan comes on and the temp gauge is still in
the low-LED area. Fan works, so maybe it's the thermoswitch, which I now
have, but not installed. Seem reasonable?
2/ Idle is still high but not as high as prior to cleaning the TVS.
Idle screw on the throttlebody does slow the idle slightly, but is set just
above full "in", or turned right all the way.
Any thoughts? Thanks
Bob Stevens
