auxilary fan acting up

[Phil Rose]

Robby,
That sounds OK to me--happens especially if the car is in motion (and 
being cooled). But if that very short intermittant running is 
happening on a hot day _while the car is idling_ and the fan shuts 
off --letting the temp climb well above the middle mark, then perhaps 
a problem. Might be a good idea to check the connector to the 
radiator temp sensor--maybe it's become corroded. As I recall, it's 
not easy to reach.

One way to check the fan is by operating the A/C (if it's still 
operational. I use mine rarely 'cause it's lost most of its freon 
over the past 21 years without a recharge!). AFAIR, the A/C should 
cause the fan to operate continuously on high speed.
