My engine recently overheated and burst the oil cooler hose. I've since replaced it, but I'm concerned that the reason the engine overheated was because the radiator fan didn't come on like it was supposed to after the coolant reached the threshold temp. I tested the fans and relays and they're all working fine.
I then tested what I think but am not sure is the radiator thermo sensor connector, by disconnecting it from the wiring harness just in front of the air filter, then shorting the harness connector with the key in the ignition all the way clockwise but with the engine off, and the fan didn't come on like it was supposed to.
Either the connector is bad or there's a break in the wiring somewhere, or I tested the wrong connector. Is this it:
I'm referring to the left and center connectors. The left one connects to the wiring harness and the center one to the thermo sensor. Are these the right ones, or is it the one on the right, or a completely different one that can only be gotten to from under the radiator?
Also, does the fusebox on the right side on the engine bay near the battery look ok?
