[V8] Cooling/ radiator question

[Kneale Brownson]

Do you know whether the electric auxiliary fan also comes on when the 
coolant temperature rises, Steve?  There is an 80-amp fusible link mounted 
in a little black box on the front of the hydraulic system oil 
reservoir.  Take the cover off and be certain the link is intact.  It can 
"look" ok, but actually have failed.  They seem to fail regularly.  No 
fusible link means the electric fan never runs.
