    What temp to set e-fans on clutch fan swap?

    Swapping out the clutch fans on a 2004 Avalanche (Vortec 5.3)

    Wondering what the stock temps are for fan on/off?

    Stock 05 settings are usually 226 and off about 200.
    I usually set them for 215 on and 200 off for fan 1.
    Fan 2 on at 215 and off at 200 but with a 20 second delay to turn on.
    Also set AC temp on at 50* so when the Ac request is sent the fans turn on low.
