Subject: radiator fan howling

[Christopher Ritchie]

the intermittent howling coming from my 89 90q has been
narrowed do=3D
wn to the radiator fan.  Is it safe for me to spray some silicon
grease int=3D
o the fan motor to see if this eliminates the problem?


I don't know about silicon grease.  I've used WD40, but that probably is no=
t
right either.

Is this fan fused?  If not, you have a dangerous situation.  A howling fan
means it about to seize.  When it does, if it's not fused, it could start a
fire.  It will certainly burn up the wiring harness.  The radiator fans on
1988 and earlier 5000s were not fused.  The retrofit is to add the fusible
link from 1989s.
