As I understand it (and wait for better authority) it should spin but stop fairly quickly. I.e., not go round and round and round.

I've never had temp issues tho. So haven't had to 'learn' about much in that department.

 

Also had some concerns about my fan clutch possibly causing higher than "normal" idle temps. Just yesterday read description/operation in both D1/D2 WS Manuals. Stone cold there should be resistance felt and not just spin freely.

......

 

if the fan spins free it is bad, there should be some resistance when you spin it

 

When cold I have lots of resistance. If I give it a good push it won't even continue.

 

Good, you eliminated that.

 

Have you been driving the beast and monitoring temps or just trying to bleed air after short warm up cycles? The bleed procedure in the D2 Manual is quick & dirty and written to get the vehicle in/out of the shop fast. The more old school D1 Manual procedure is done engine running & with cap off and probably gets more air out of the system.

Have you changed the temp sensor/sender? Inexpensive and yours may be slightly off giving the higher reading.

......

 

Regretfully I have not been driving the big silver pig. I'm worried it will overheat at a stoplight, or in the ridiculous mall traffic I go through every day. I did however change the temp sensor on the intake.

I have been letting it idle until the auxiliary fan kicks on, at which point I bring up the revs, watch the temps drop dramatically, then shut it off. If that is a bad idea.. please say so. I did run it for a very short stint without the pressure cap, it seemed to heat up faster? May have been my imagination or paranoia.

 

Quite possible, or maybe the air in the system is heating up faster than the coolant.

This is gonna sound absolutely crazy, but its up to you to try.
We call it burping it. make sure your level is at the cold mark, and beat the hell out of hit. Stay on the throttle. The whole time. When i replaced my radiator, that what i did. temp was erratic after, so the 12 mile ride from the shop to home was full throttle the whole way, and if it wasnt full throttle, it was 2nd gear. Then when i got home, parked the side with the reservoir on a curb and left it overnight. level dropped and temps have been predictable.

But I'm a factory trained greasemonkey....so results may vary.

 

when i had trouble bleeding mine i install my pressure tester.
put a pear of vise grips on the upper heater hose and removed the hose from the heater core, all the air in the system came came right out thru the heater core.
slid the hose on while the coolant was coming out and have never had a problem

 

More than one way to skin a cat.
