2001 Merc Sable Low Coolant Light

01 Merc Sable with a DOHC 24 valve engine, 97K miles. Low coolant light comes on and coolant is not low. Temp is normal.

dirty sensor cable connection

So where is this connection? I cannot find the sensor for the low coolant. The schematic just shows the low coolant light going to something called General Electric Module. Cant find that either.

i had the same problem on a ford and it was the wire going into the coolant container sensor

look at the bottom of the resivoir (overflow) container. sensor may be there although im not familiar with that modle.

That was my first thought, but there does not appear to be a sensor in the reservoir. No wires going to it at all, and when I reviewed the removal procedure in the Chiltons manual, there was no mention of disconnecting or removing of any kind of a sensor. The schematic shows the low coolant light connected to a unit called a General Electric Module. No mention of where this module is elswhere in the book.

Check for it, the sensor, on the radiator. It should be 3-4 inches down from the top.

( My 2001 Impala needs yet another new one, this will be number 3 for me)

I assume that you have checked the radiator to make sure it is full.

Had the same problem. The sensor is on the bottom of the resevoir. The sensor is a magnetic sensing shaft that responds to a floating magnet in the resevoir. In my case the float was not free to move. I took the resevoir off and flushed it with a hose. I think I could have left the resevoir on and sprayed it with a hose with a nozzle.....that probably would have done the trick. Problem solved, 1.0 hours, no parts to buy.
