Now I need info. Today my car overheated after I left big box store I practically live at. :) I had to quickly turn around and head back there after noticing temp gauge reading 3/4 to hot with check gauges light flickering. I knew I needed more coolant and presumed I was low. But when I popped the hood, with the car running, I noticed the fan was not running. I let the engine cool while I went in and got the anti-freeze. Then I did some testing. Ended up going to nearby junk yard and got fan relay switch. While yard attendant was getting the new switch, the engine cooled down and I opened the radiator cap and level was low so I added coolant. Then he came, installed the new used relay, idled the car for a while, and the fan worked. Then I thought to myself, "Silly me. Telling people not to buy parts if you don't need it." I got thinking (too late of course) that MAYBE it was the low coolant level the whole while. That even though the thermostat area of the engine was most likely pretty hot, that probably no coolant was actually touching the temp sending unit inside. And MAYBE the sending unit needs coolant, rather than hot air to be touching it? But then I also reasoned that perhaps the car overheated FIRST because of the bad fan relay?, and sent coolant bubbling into my resevoir (which it did), and then because the level was low now in my radiator, that this is what caused the overheating. So which is it? I could take the new used relay out, if I have to and test again with my old relay. But does anyone else here plain know the answer to my question? I think it is good that everyone knows the answer, anyway, as running low on coolant is something many people encounter, and those sending units are at the high point in the engine, and thus probably all vehicles behave the same way, regarding whether or not coolant touching the sending unit is required, instead of just hot air touching the sending unit. I also could destroy the relay and look inside it, but I don't want to do that in case it is good, and this would give me a spare.
