[s-cars] Manual Control of afterrun pump and fan

[Sean Douglas]

I did something similar, but instead of a dash switch, I installed a
thermo switch (034 919 369 A)that measures air temperature under the
hood and is set to come on at 85 celcius. I mounted the switch on the
right side of the engine, near the back just above the downpipe. I
removed the wires from the stock coolant temp switch and ran them to the
new switch. Now when I run my car, the after-run pump and fan comes on
about 80% of the time.
