Bill,
I thinksomeoneposted a similar probablyrecently. I'm not sure if it was this cadillac forum or not though?

They stated the sensor was in the coolant reservoir, but it turns out the problem was the connector tothe coolant reservoir was broken.

Hopefully the pros will chime in.
What year andmodel do you have?

Jasper,it is a 2000.i checked the reservoir over and under and did not see it,not saying i did not overlook it,but i will look again in the am.thanks for the reply and if anybody else has other views please reply,thanks again in advance,Bill

 

Hate to state the obvious but did you top up the resovoir? I believe a level of anything over an inch below the filler base will trigger the message.

 

FYI. Here's the link to theproblemImentioned.

google search "I found my leak, now i need help"
