[s-cars] Radiator fan not blowing

[Fred Munro]

Bill;

With the AC on, the electric fan should run at low speed. If it doesn't,
check the relay and the fan connector down by the intercooler - these are
known to fry with the current the fan pulls. The fan may also have am 80 amp
fusible link in the ground wire - can't recall for sure. If all that is OK,
the resistor pack or the motor may be toast.

The belt-driven main fan just idles until the air coming through the rad
gets hot enough to engage the viscous clutch. If the engine is overheating
and the clutch is not engaged it is likely shot. Changing the clutch is
fairly easy but you'll need a 5 mm pinwrench to hold the pulley and I think
it's a 32 mm open-end wrench to remove the clutch.

Folk's,
So, while taking kidz to famous daves bbq, stuck in traffic, suddenly we
start over heating.
Pull over, let it cool a bit and drive a couple minutes to the restaurant...
no issues.
Eat and let car cool for an hour or so, while I surmise it's something with
the fan since its Aokay when we are moving.
So, we make it home, no issues but I do try to keep moving and leave AC on
thinking that fan will turn.
The main fan however just seems listless and I can stop it with my hand
wearing mechanic glove.
So, might this be the fan motor, fan clutch, fuse (will check) and more
importantly is this a DIY and would the parts be available, like, tomorrow?
IOW, could this be completed for sfest departure Thursday afternoon or... do
I upscond the wifes D2?
