for many turns without ant resistance whatsoever. Same story when I turned it clockwise.
Does it all mean that it is time to change the fan clutch?
Can you guys performe this simple test on your trucks and let us know about results, please?
Thanks a lot!
That's a pretty useless test, if I understand correctly how these things work. Stationary resistance is meaningless because it is a 'centrifugal' clutch and it has to be spinning for the fluid to reach the places where it causes the clutch to engage. I recently changed mine, and I had the old, bad one sitting next to its replacement in front of me. Both were identical in their resistance to turning (some, but not much). Many swear by the magazine test, but I believe that is somewhat hit or miss. The most dramatic difference on the replacement was the return of the roar of full engagement at start-up of a cold engine. If you don't have that, your clutch is dead.
