cooling fans for 1992 100

[Elliott Potter]

i'm not sure how it is in the 100, but in the 90 V6 cars there is a big
heatsink (maybe 8" tall and 5" wide, shaped like   \___/  ) mounted on
the front driver's side of the engine bay, accessible from underneath
the car.  There are three big VR's on it, and the top one (again, on the
90) is where the positive wire on each fan plugs in.  There's also a
ground point nearby, just around the front corner for the ground wires
for each fan.
