remember the radiator needs to be hot for it to work "not just the block"

my fan switch is on the rad DRIVERS side unplug it and jump the wires,the fan should come on"bad switch"
if it dont,pull the pulg off the fan and test it for 12V while jumping the switch wires
if you get power switch is good and fan is bad.
