Low coolant warning and slight overheating - 93SSEi

Low coolant warning and slight overheating - 93SSEi
I have a relatively young, 78K miles, 93SSEi, which I bought recently. The "Low Coolant" warning icon comes on about half the time. A visual check of the radiator and overflow tank shows full coolant levels in both. The only other symptom is that after extened idling, like waiting in a line at the gas station and then shutting down the engine the temperature guage reads a bit high, pointer at about 2 o'clock, and the engine doesn't want to start.
The questions that come to mind are....
1. Where is the coolant level sensor? Is there a way to test whether it'* bad or not?
2. Is the low coolant warning indicating a possible circulation problem?
3. Is the after idling temperature too high or is it that the fuel computer just isn't handling the hot start properly.
If this explanation isn't clear, please email me directly at peterwoodbury@***.net and I can clarify or can call back to explain more fully.
Thanks for this forum. It has already saved me one trip to the locksmith to program my clicker.

:( Sorry to hear about the over heating... I had a simlar problem with my 92 sse... Right before my radator went on me...
2 pieces of advice...
First Check to see if your water pump is working...
Second Flush your coolant system... it could be something as simple as a block in the line some where...
other then that... 1800radiator... Cheap and has what you need with out being Crap...

The low coolant sensor is most likely your culpript, my old Bonneville did that, so i unplugged the sensor, and fixed. The sensor is below the rad cap a few inches and has a small wire harness plugged into it. The car warming up more than normal at idle is normal, but, maybe a coolant flush and thermostat change is in order for you..cant hurt anyways.

Welcome to the club and Merry Christmas! Congratulations of getting a low-mileage '93. That is a special and desirable year for the SSEi.
The low coolant sensor is prone to failure giving false indication of low coolant. As long as you keep an eye on your coolant levels, and temperature gauge, you can safely unplug the thing and stop the false reports (and dinging) on your DIC.
The running hot is another issue. My '92 SSEi rarely goes above 200 F, and that is with the stock (195 F) thermostat. Many here will advise replacing the 195 with a 180 F thermostat. Many miles with the 180 on this site, and no apparent negative effects.
It is possible that your temperature gauge reads a little higher than it should, but I don't recall that problem reported here.
