Ok, my 91 GT has the Check Coolant light flashing occasionally, then going off. Theres plenty of coolant in the radiator and the resivoiur. Any thoughts?

Have you check the water pump?

When my EB did that, I found that the radiator needed flushing out. It had plenty of coolant, but blockages were stopping it from circulating very well

I thought it may be the water pump, but from what I gather, the water pump dying, or even failing completely, would not trigger the CHECK COOLANT light. Someone PLEASE let me know if I am wrong about this. I thought this light could only be triggered by lack of coolant in the resivoir/radiator. I should flush it, though, and I'll see if it helps any.

There should be a sensor located in the expansion bottle. This signals a low coolant level, nothing more. Some types have a float and magnet type of setup, sometimes the moving parts inside can stick which will occur with the normal surging of coolant on acceleration/deceleration.
