Unplug the ecm and ground the wire on the ecm harness that goes to the low speed relay trigger see if the fan comes on. This will tell us if all the wiring from the ecm to the relay are good.

Lets go back to the beginning, the car started to overheat: before I changed the intake manifold gaskets, the thermostat, oil, coolant temperature sensor and antifreeze. : Also I turn the car on today checked the lower hose again and half of it was cold again.

Alright well we were trying to figure out why the low speed was inop and only your high speed fan comes on at 230 degrees. Both the upper and lower radiator hoses are supposed toget really hot if there not you dont have coolant flow thru your engine.
