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.
