Rattle coming from the front of the motor

[UNOMYFLO]

If I remember correctly F5 said the fan mech is not electronic rather it has a heat sensitive bushing in it which when it reaches a certain temp the bushing expands and engages the fan itself causing it to rotate.

The fan mech and snout not the fan should always spin but again when the bushing heats the play goes away the bushing expands and the fan turns with the fan shaft.

Why then do our fans run instantly when the H3 is cold?

Th electronic fan mechs turn on when the sensor reaches temp and tells the computer to turn the fan on...if ours is not like this why does it spin when its 20 outside?


And not to beat a dead horse mine does not do it (the metal rattle sound) when the temps are higher...it was 78 today here in GA and it did not do it last week when it was 32 it was a loud rattle

Makes no sense to me really..
