I flushed the radiator - cloudy water came out but no chunks

I flushed the block - again, cloudy water but no chunks (this process ran water backward through the thermostat - block - waterpump ... no blockage).

I'm almost ready to give up & take it to the stealership.

I still want to check the rest of the fuses to see if that's why the fan isn't kicking on (just a shot in the dark tho since they kick on with the AC).

Cooling system is supposed to be SIMPLE!!!
