ATTN: Cad 500 nuts

My Cad controls its H2O temperature just fine. On the 900 mile trip last
week, mostly in 90+*F temperatures, it stayed between 198*F and 202*F at
least 99% of the time, with occasional excursions as low as 196*F or as
high as 203*F. BUT, the fan clutch stayed engaged about 50% of the time!
Which might indicate that I need more cooling capacity. But the
engagement seemed to have NO correlation with the temperature; in fact, it
almost seemed to be inversely correlated: At times the clutch would engage
with the temperature at 198*F and disengage at 202*F! Thus, the problem is
NOT that the AL radiator is inadequate. Obviously, the engagement
temperature of the clutch is just too close to the engine's normal
operating temperature.

So, yesterday I decided to install one of the bargain standard 455 fan
clutches I bought when they were so cheap on eBay recently. Uh-oh! I
forgot -- the WP bolt pattern is different on the 500! Looks like Alan
gets a couple of free spares.

My question now is, "Who's REAL happy with their Cad500 fan clutch and what
is it?"
