This may sound odd, but I never recall my original fan spinning at idle and within 2-3min of idle warmup. Does that mean it was already on its last leg when I took off?
The electric cooling fan is enabled when...The electric services when the a/c is on. ...
Indeed that fan does. Begs to wonder why as it doesn’t do too much to help when above 221. Unless the few posters that have high temp issue still see little overcoming a slight incline with an inoperative main fan and presumably a good electric. Which brought me to my solution.
How do you tell the difference between the noise of the electric fan and the oft-reported "roar" of the viscous fan?The times that the electric fan kicked on (the noise was noticeable)
You know by the sound…. Another is to get out and look to learn the difference is my experienceHow do you tell the difference between the noise of the electric fan and the oft-reported "roar" of the viscous fan?
So at 80%, fan clutch sounds like it could be a "Root Cause" here?I would say some ~80% of cooling system issues reported here are due to failed fan clutches. The remainder (not counting leaks) are stuck thermostats, and clogged radiators (internal and external).
Do you know the full throw of the expanding spring? Sounds like 1/8" or so.Just bend the spring outwards about 1/8" with a pair of pliers.
No220F in 100deg. ambient normal?
Approximately. I heated the spring up with a hot air gun. Might be 3/16" max on the unit I have.Sounds like 1/8" or so.
