I feel there is a sort somewhere in the fan circuitry, check its fuse unit. Also ensure proper level of engine oil is present in the engine. Actually your car might be overheating because the respective fans are not powering on at the correct time, but you mentioned that these fans are in working condition so it has to on something in this circuit that is preventing completion of this circuit by their respective sensors which you have recently changed...............sodeep

Testimonial: "Thank you very much. It will save a lot of money on a repair if I can do it myself. God bless you."
You are off to a good start by testing the fans. Get a repair manual from your nearest autoparts store. I find them invaluable. Most temperature sensors can be tested with an Ohm meter. Or short the two wires together to trigger fans. If it has only one wire then ground it to the frame/body (negative side of battery). If none of that works (with ignition on / car off) then relay is bad. Also turning on the A/C should make the fans come on. Car does not have to be running, key in on position. This would eliminate bad relays or not.

SOURCE: where is the coolant temp
you have two ECTs on this car on the right side of the block and other close to the water pump. I would suggest replacing both of them while you at it. Good luck
