I replaced my fan clutch because of the roaring.
2006 trailblazer
4/4 I6 67000 miles
Owned since new this is my first fan clutch also replaced water pump and thermostat
Water pump noise and small leak thermostat due to only warming to 165 degrees F.
My question is do I have to do a relearn for my new fan clutch. Fan clutch runs until engine is warmed up. The old fan clutch didn't do that.

No relearn required and it's normal for it to go full blast for a few minutes while the cold silicone redistributes itself. I think it's even in a GM bulletin somewhere.
